  • HYDROGEN SUPPLEMENTS – ACTIVE H2 ULTRA and MEGAHYDRATE

    Fred Liers PhD hydrogen supplements Active H2 Ultra MegahydrateSupplemental hydrogen is fast becoming essential in many people's nutritional supplement regimens. Why? Because hydrogen offers significant health benefits, including excellent antioxidant protection, increased energy, faster recovery, and improved well-being. Who doesn't want those benefits?

    My favorite way to take hydrogen is to make hydrogen-infused water, or what I call a hydrogen "fizzy" drink. Two products I like best are Active H2 Ultra tablets and Megahydrate (available in powder and capsules). Active H2 Ultra provides molecular hydrogen (H2) and Megahydrate provides hydride (H-). Both are great standalone formulas, yet work well together as each provides unique means to quench free radicals effectively.

    MAKE "FIZZY" HYDROGEN-INFUSED WATER WITH ACTIVE H2 ULTRA

    Drinking H2-rich water is an easy and effective method for obtaining hydrogen, according to the Molecular Hydrogen Foundation. Making hydrogen-infused water is simple and convenient, as you can drink it at home or while traveling. Effective hydrogen products HPDI carries include Active H2 Ultra tablets, Megahydrate powder, and Megahydrate capsules.

    My favorite hydrogen drink contains both Active H2 Ultra and Megahydrate. I take these products separately at times, but find it easier to take them together—and gain the benefits of both immediately.

    Active H2 Ultra Megahydrate Active H2 Ultra tablets and Megahydrate powder work together for major antioxidant power.

    INGREDIENTS – HYDROGEN-INFUSED WATER

    • 1 Scoop Megahydrate powder (500 mg) or 1 Megahydrate capsule (600 mg)

    • 1 Tablet of Active H2 Ultra

    • 8–16 Ounces of Purified Water

    DIRECTIONS: Put one scoop of Megahydrate powder (or open one capsule) into your container of water. Let sit for about 30–60 seconds. Drop in one Active H2 Ultra tablet. Allow it to effervesce for one minute or until fully dissolved. Drink immediately. For best assimilation, preferably take on an empty stomach at least 10–15 minutes before food. Wait one hour after eating to drink hydrogen-infused water.

    Note: Do not wait long after effervesce stops to drink the water because hydrogen will escape into the air. Alternatively you can cap the container with a lid, and this will allow the hydrogen to last a while longer.

    Molecular hydrogen is sufficiently small to pass through glass, so use a metal container if you plan to cap it. If you drink immediately, then the type container you use won't matter. I personally prefer a glass mason jar. This allows me to see the tablet dissolve, but also means drinking it immediately.

    I make 1–3 hydrogen fizzy drinks daily, first in the morning and then in the afternoon, but almost never in the evening as it can be energizing. I drink hydrogen water on an empty stomach. I gain a significant energy boost, but also other benefits, including improved athletic performance, faster recovery from exercise, and an overall greater sense of well-being.

    I highly recommend you try hydrogen supplements for yourself, and then consider them for your clients or patients. Our experience is that most people are pleasantly surprised by the results they get from hydrogen supplements, especially if they have a need for exceptional free-radical defense, or stand to benefit from the proven effects of hydrogen (see list below).

    You will want to continue taking hydrogen supplements regularly because the benefits are so significant, especially over time. Let the power of hydrogen starting working for you.

    Active H2 Ultra is a fast-effervescing tablet.

    MOLECULAR HYDROGEN BACKGROUND

    More than 1,000 scientific studies indicate molecular hydrogen offers therapeutic potential in 170 disease models, and every organ of the body, according to the Molecular Hydrogen Institute.

    Hydrogen is an antioxidant. It is also an extremely small molecule that can penetrate even the tiniest cellular compartments. This helps explain how hydrogen works to offer free-radical defense throughout the entire body.

    The medical and scientific literature is clear. Hydrogen's modes of action:

    H2 reduces oxidative stress as a selective antioxidant and by maintaining homeostatic levels of glutathione, superoxide dismutase, catalase, etc.

    H2, like other gaseous signaling molecules (i.e. NO, CO, H2S), appears to have cell signal-modulating activity affording it with anti-inflammatory, anti-obesity, and anti-allergy benefits.

    We include hydrogen supplements in HPDI's system of Foundational Supplements. In fact, hydrogen formulas as just one of six foundational supplements. We consider hydrogen a "secondary" foundational supplement usually to be added to a supplement regimen after the four primary ones: multivitamins, antioxidant & vitamin C formulas, essential fatty acids, and superfoods high in dietary nucleic acids (i.e., Rejuvenate! superfoods).

    THERAPEUTIC USES OF HYDROGEN

    The scientific literature discusses the use of molecular hydrogen for many clinical applications, including:

    • Metabolic Syndrome including diabetes, hyperlipidemia, arteriosclerosis, hypertension, and obesity

    • Ischemia/reperfusion injuries, including cerebral and myocardial infarctions, organ transplants, post-cardiac arrest

    • Neuroprotection, including applications for dementia, Parkinson's disease, depression, and anesthesia

    • Inflammation, including applications for polymicrobial sepsis, rheumatoid arthritis, wound healing, and bowel diseases

    • Mitochondrial diseases

    • Hemodialysis and ventilation

    • Aging, including cognitive decline

    • Exercise, including applications for fatigue, lactic acid, recovery, and oxidative stress related to heavy exercise

    Side effects of cancer therapies, including radiotherapy and chemotherapy

    • Many other benefits

    HOW HYDROGEN WORKS

    According to the Molecular Hydrogen Foundation, there are three ways molecular hydrogen exerts positive health effects:

    1.  Molecular hydrogen easily diffuses into subcellular compartments where it scavenges cytotoxic oxygen radicals, thereby protecting DNA, RNA, and proteins against oxidative stress.

    2.  Molecular hydrogen triggers activation or upregulation of additional antioxidant enzymes (e.g., glutathione, superoxide dismutase, catalase, and others) and/or cytoprotective proteins of the body.

    3.  Molecular hydrogen may be a novel signaling molecule that alters cell signaling, cell metabolism, and gene expression. This may explain its apparent anti-inflammatory, anti-allergic, and anti-apoptotic (or anti-cell death) effects.

    Notably, two of these three mechanisms of action involve antioxidant activity. Hydrogen is one of the best antioxidants for all the reasons discussed, and we believe it acts synergistically with other antioxidants, including Vitamin C, glutathione, and Nrf2 activators (like those in HPDI's Ultimate Protector).

    MEGAHYDRATE MAKES MOLECULAR HYDROGEN BETTER

    Why add Megahydrate to your hydrogen-infused water? Because Megahydrate provides hydride, the negative anion of hydrogen, or H-. Thus, a tiny scoop of Megahydrate provides vast quantities of electrons available to quench free radicals. Unlike molecular hydrogen, which dissipates quickly into the air, and therefore must be consumed immediately, hydride rich water (about -700 ORP!) may last for three weeks in an active state. That is a good reason to take Megahydrate by itself whether or not you already use it with molecular hydrogen in your hydrogen "fizzy" drink (see recipe above).

    Megahydrate Active H2 Ultra Megahydrate (powder or capsule) provides hydride (H-) for free radical defense.

    The interesting thing about H- is that after it gives up its electron, it becomes simply "H" or atomic hydrogen. It then looks to pair up with another "H" to become H2, which is molecular hydrogen. In this way, Megahydrate not only gives you large quantities of stable H- and potent antioxidant capabilities, but also then creates molecular hydrogen in your body. This means it becomes a different kind of antioxidant, H2, which is therapeutic in itself.

    By adding Megahydrate to your hydrogen-infused water (as described above), you create a unique "double whammy" drink in which you maximize the powers of hydrogen (H2 and H-) to create and maintain good health.

    Note: Megahydrate powder is more cost effective than Megahydrate capsules, which must be opened into the fizzy drink. However, Megahydrate capsules are convenient for traveling and are easy to take by themselves. I keep both available, so I can use either one depending on my daily needs.

    DRINKING HYDROGEN-INFUSED WATER

    Drinking H2-rich water is an easy, effective method for obtaining hydrogen according to the Molecular Hydrogen Foundation. Drinking hydrogen-infused water is convenient as you can drink it at home or while traveling. Effective hydrogen products HPDI carries include Active H2 Ultra tabletsMegahydrate capsules, and Megahydrate powder.

    As noted, I make 1–3 hydrogen drinks daily using Megahydrate and Active H2 Ultra. I drink them on an empty stomach. I enjoy a significant energy boost, which helps power me through my day. I gain other benefits, including improved athletic performance, noticeably faster recovery from exercise, and an overall greater sense of well-being.

    The nice thing about hydrogen supplements is how flexibly you can use them. While I typically prefer to make hydrogen-infused "fizzy" drinks in water, I will often sip Megahydrate-infused water by itself during the day or even in the evening (as it is less energizing than molecular hydrogen).

    Megahydrate does not immediately lose its potency in water, so it can be casually sipped. Also, if you're traveling or on-the-go, you can simply swallow a Megahydrate capsule by itself. Finally, you can carry Active H2 Ultra tablets with you wherever you go, and add them to water whenever convenient for you.

    Megahydrate Active H2 Ultra Megahydrate and Active H2 Ultra create an ultra-healthy hydrogen 'fizzy' drink.

    TRY HYDROGEN!

    Try hydrogen supplements for yourself. Then consider recommending them to client, patients, friends, and family. Most people welcome the results from hydrogen. This is especially true if they need exceptional free-radical defense — and who doesn't? We can all stand to benefit from the proven health benefits hydrogen uniquely provides.

    After you try hydrogen, you will want to continue taking it. Hydrogen-infused "fizzy" water can become your go-to drink. Remember, hydrogen works best when taken consistently and daily!

  • RESTORE GUT HEALTH FORMULA + VIDEO

    Fred Liers PhD restore liquid mineral supplement gut healthHeard of RESTORE liquid mineral supplement? If not, you're about to discover something important for gut health.

    RESTORE™ is formulated to help restore gut health. It works by strengthening the integrity of tight junctions in your intestinal wall.

    Maintaining tight junctions is important because they protect your body from substances entering the blood stream. Restore also supports the communications systems of the bacteria in your microbiome.

    Tight junctions are natural barriers protecting the lining of your gut barrier, organs such as kidneys and heart, and the blood-brain barrier thereby keeping out unwanted substances. Even as we take in nutrients from the GI tract, the function of tight junctions is maintaining the integrity of the gut wall and other barriers that protect the body.

    These days, our gut membrane has a tough job keeping out unwanted substances. Because tight junctions are weakened by many things, including highly processed foods, especially those containing gluten and gliadin, the herbicide glyphosate (the primary ingredient in RoundUp weedkiller), and other exposures like electromagnetic fields (EMF) from digital devices and Wi-Fi networks.

    As a result of weakened tight junctions, undesirable substances from food proteins, harmful chemicals and other toxins can slip though into our bloodstream. This can lead to a powerful immune response that can weaken immunity and cause significant inflammation. Foreign substances in the bloodstream can also result in extreme food allergies and food sensitivities to various toxins entering the body.

    We live in an age in which our microbiome health is under assault.  Studies show our ancient ancestors had 20,000–30,000 different strains of beneficial bacteria in their GI tracts. Many people today have just 5,000 or less. Why is that?

    There are many reasons for low microbiome diversity. These reasons include antiobiotic use (both from pharmaceuticals and foods), glyphosate (which essentially acts like an antibiotic), processed foods (especially those containing gluten and gliadin), and systemic degradation of the gut environment rendering it less hospitable for maintaining health populations of gut flora.

    These impacts are significant because diversity in your microbiome not only supports gut health, but also appropriate  brain health, immune system health, and overall vitality. Restore acts as a "microbiome fertilizer" helping establish and maintain healthy microbiota.

    In fact, Restore contains important "redox" molecules produced millions of years ago by existing soil bacteria. These molecules are an important part of communications systems within the body between gut bacteria and with the body's mitochondria. These communication systems play an important role in establishing proper homeostasis throughout the body.

    REASONS TO USE RESTORE™

    There are important reasons to try Restore—whether or not you experience significant gut health issues. These reasons include:

    • Maintaining strong tight junctions for mega membrane health, and helping the body restore tight junction integrity

    • Creating an environment in which beneficial bacteria can thrive

    • Boosting microbiome diversity

    • Healing the gut

    • Mitigating the adverse effects substances like antibiotics, gluten/gliadin, glyphosate, and GMOs on microbiome health

    • Supporting immune system function

    • Protecting integrity of blood-brain barrier

    Other benefits include support for respiratory wellness, enhancing mental clarity, and promoting proper homeostasis throughout the body.

    For all these reasons and more, you should consider taking Restore. You can start by taking one teaspoon or less daily, and gradually increasing your dose to one tablespoon or more.Restore for gut health liquid supplement

    I have taken Restore daily for more than two years, and benefit greatly from it. The most noticeable effects are a complete cessation of spring allergies (after two decades of worsening symptoms), greater clarity of thinking, and improved overall well being. I have seen other people get good results with a variety of conditions from dysbiosis to gluten/gliadin sensitivity.

    MORE ABOUT RESTORE™

    You can learn more about Restore on our website. Also, the Restore website offers in-depth information and videos. Here is how the Restore website and Dr. Zach Bush describe the formula:

    Restore is a dietary supplement supplying first line defense against daily exposure to environmental and food-borne factors. It helps create an optimal environment or ecology in the gut membrane for beneficial or "good" bacteria to flourish. Beneficial gut flora protect your immune system and maintain health. Restore is a scientifically proven soil-derived mineral supplement designed to support protection of the intestinal walls.

    Restore protects the entire gastrointestinal (GI) tract against agricultural herbicides, antibiotics, GMOs, gluten, and food-borne toxins. It helps create an environment in which 20,000–30,000 different strains of beneficial gut bacteria can thrive. This is a far different mode of action from probiotics, most of which contain just 3–30 strains of beneficial bacteria.

    Restore helps create a strong immune system along with proper gut function. Microbiome balance and tight junction integrity are known to constitute a significant part of the immune system. They directly affect DNA transcription of cells to promote optimal health and prevent a leaky gut syndrome, thereby improving gut intelligence.

    Seventy percent (70%) of our immune system is found in our gut. We need tens of thousands different strains of good gut bacteria to support a healthy immune system. Clinical experience, in addition to cell culture studies, support the theory that Restore’s proprietary formula creates the optimal environment in the gut to create a tight junction barrier and maintain our health and wellness.

    Restore is a daily liquid supplement designed to support the protection of the entire gastrointestinal (GI) tract against agricultural herbicides, antibiotics, GMOs, gluten and food-borne toxins by helping to create an environment where between 20,000-30,000 different strains of good gut bacteria thrive. Most probiotics on the market contain fewer than 24 different strains of good gut bacteria.

    TRY RESTORE™

    Restore is ideal for individuals suffering from gut health issues. Yet, it is also excellent for supporting and maintaining gut health generally. That is the reason we at HPDI consider Restore important enough to designate as a foundational supplement, one of the top six supplements you need for good health.

    Given the safety and effectiveness of Restore, there is broad applicability for its use. This is especially true because gut and microbiome health are under constant assault. These assaults range from multiple environmental and lifestyle factors—including poor diets high in processed foods, antibiotics in pharmaceuticals and animal foods—to massive glyphosate (herbicide) contamination of foods, soils, air, and water.

    Let Restore be your first line of defense against assaults on your gut health, tight junctions, microbiome diversity, and immune function. As it says on the bottle, "Complete well-being begins in the gut."

  • PRO-C ANTIOXIDANT FORMULA UPDATE + VIDEO

    Dr. Hank Liers, PhD pro-c™ pro-c super antioxidant formulaFred Liers PhD pro-c antioxidant vitamin c nrf2 formulaLooking for an advanced antioxidant formula? Already using or recommending vitamin C? Curious about cellular Nrf2 activation? Look no further than PRO-C™.

    PRO-C™ is among the most effective antioxidant formulas available. It is an HPDI foundational supplement that works most effectively when used with multivitamins, essential fats, and superfoods. However, it is also an excellent standalone formula that can rapidly provide the body with extremely high protection from free radicals.

    We ourselves have taken PRO-C daily for many years with excellent results. Our personal experience together with detailed feedback from health professionals and end-users affirms the effectiveness of PRO-C as a super-antioxidant–vitamin C-Nrf2 activator formula.

    PRO-C provides 500 mg of buffered vitamin C per capsule (buffered with calcium, magnesium, and zinc) along with grape extract (seed, skin, pulp) and green tea extract (95% polyphenols). In addition, we include a special combination of the "network antioxidants" l-glutathione (reduced), n-acetyl-l-cysteine (NAC), r-lipoic acid, and selenium. Vitamin B2 and Vitamin B6 in coenzyme forms support the enzymatic effectiveness of the "network antioxidants." The formula works so well because this combination of ingredients leverages the antioxidant power of vitamin C, grape extract, green tea extract, and the other nutrients to act synergistically in order to maximize effectiveness.

    FORMULATION HISTORY AND THE SCIENCE BEHIND PRO-C™

    What you may not know is the history of the development PRO-C and the scientific knowledge on which Dr. Hank Liers based his formulation of it.

    Dr. Hank formulated his first product in 1989. It was a potent antioxidant formula he called PYC-C™ (sounds like "pixie"). PYC-C consisted of a combination of buffered Vitamin C (including magnesium, calcium, and zinc ascorbates) and pycnogenols from pine bark.

    Much of the scientific research data Dr. Hank collected during the development of PYC-C regarding oligomeric proanthocyanidins (OPC) he later incorporated into an article (currently published on this blog) titled "Review of Scientific Research on Oligomeric Proanthocyanidins (OPC)" (rev. 2017)

    By 1997 Dr. Hank had gathered a great deal of new scientific information regarding green tea catechins and the nutrients termed "network antioxidants" by Dr. Lester Packer, director of Packer Lab at University of California, Berkeley. Beyond this information, Dr. Hank studied additional research regarding how various nutrients worked together synergistically. At that point, he was ready to formulate the new, improved PRO-C™ super antioxidant formula.

    PRO-C combines the ingredients of PYC-C (now known as OPC-C™) and uses grape pulp, skin, and seed extract with green tea extract (with high polyphenols >95% and EpiGalloCatechinGalate (EGCG) >45%), n-acetyl-l-cysteine (NAC), reduced glutathione (GSH), R-lipoic acid, selenium, and coenzyme Vitamins B2 and B6.

    PRO-C super antioxidant formula 180 cap 90 cap

    HPDI launched PRO-C™ in late 1997. It rapidly became one of our best-selling products. Our customers raved about how effective it was for them if they felt like they were "coming down with something" (like a cold, flu, virus, infection, etc.). Greater skin elasticity greatly helped pregnant women avoid stretch marks and episiotomies. Today, we highly recommend its use together with our other Foundational Supplements to ensure optimal health and anti-aging effects.

    THE PRO-C™ SUPER ANTIOXIDANT FORMULA

    PRO-C™ super antioxidant formula is extremely synergistic, especially in so far as it increases the body's ability to quench free radicals in its aqueous (i.e., water-based) compartments. Because antioxidants may become free radicals themselves after they have done their job, the body has developed an elaborate system for recovery of oxidized antioxidants.

    Dr. Lester Packer was the primary researcher investigating the synergistic character of antioxidants. He made this statement in his interview with Dr. Richard Passwater after publication of Packer's The Antioxidant Miracle (1999):

    [The major theme of] The Antioxidant Miracle is that antioxidants work in a coordinated manner. They interact with one another, and this interaction, which we like to call the antioxidant network, is very important to the overall antioxidant defense that we possess. The key members of the antioxidant network are vitamin E and vitamin C, but there are other participants in this network. These are thiol antioxidants, antioxidants that contain sulfur groups in the body. Glutathione perhaps is the best known of these, but there are other sulfur-containing antioxidants that also are very important."

    Dr. Packer continues:

    "This whole antioxidant network works like an orchestra depending on individuals who have, of course, different complements of antioxidants depending upon their nutritional regimens and the individuality of their own body metabolisms. The idea behind having a network of antioxidants is that if one antioxidant happens to be deficient the others can compensate and still keep the antioxidant defense system strong."

    The following diagram shows some of the relationships in the antioxidant network and how they support each other.

    Lester Packer antioxidant network diagram                                                Figure 1 – Dr. Packer's Antioxidant Network

    We see, for example, reduced glutathione (GSH) has the ability to reduce oxidized Vitamin C back to its unoxidized state. Vitamin C reduces oxidized Vitamin E back to its unoxidized state, and both reduces glutathione and spares it for other important functions, including detoxification and immune enhancement.

    Many polyphenols (e.g., oligomeric proanthocyanidins (OPCs), anthocyanidins and catechins) found in red grape and green tea extracts spare Vitamin C and glutathione in the body, as well as operate as powerful antioxidants, anti-inflammatories, and connective tissue strengtheners.

    grapes grape extract antioxidant Grapes provide antioxidant nutrients such as polyphenols, OPCs, anthocyans, and resveratrol.

    R-Lipoic Acid (see abstracts below) operates as an antioxidant both in its oxidized and reduced states, reduces the oxidized forms of both Vitamin E and Vitamin C, and and has been shown to enhance glutathione levels. Because several of these substances are able to protect Vitamin E contained in cell membranes, this combination also has a significant beneficial effect on the fat soluble antioxidant status of the body!

    The nutrients in PRO-C have been carefully selected and balanced to provide optimal effects, especially as related to free radical protection, detoxification, immune system enhancement, connective tissue strengthening, and reduction of inflammation. PRO-C therefore provides outstanding nutritional support in a wide variety of conditions of poor health, as well as acts to support and maintain a state of health and well-being.

    It the last several years the research results on Nrf2 activators have become well known and products developed that take advantage of these nutrients. For details see our blog article Natural Phytochemical Nrf2 Activators for Chemoprevention. Researchers have been studying specifically how enzyme-activating substances such as OPCs and anthocyans activate a transcription factor known as Nrf2 that causes the body to endogenously produce higher levels of a wide variety of protective enzymes including superoxide dismutase (SOD), catalase, and glutathione peroxidase.

    Although we did not know about Nrf2 activators in 1997 when we formulated PRO-C, we have subsequently learned that four of the ingredients in the formula have powerful Nrf2 activity. These include grape seed extract, green tea extract, NAC, and r-lipoic acid. With this knowledge, we now understand that PRO-C provides both powerful external antioxidants (with extremely high ORAC5.0 values) that support redox cycles within the body, but also provides ingredients that allow the body to endogenously produce powerful protective enzymes for even greater free-radical protection and health.

    PRO-C™ ANTIOXIDANT FORMULA INGREDIENTS

    PRO-C contains buffered vitamin C (in the form of powdered calcium, magnesium, and zinc ascorbates), high-potency grape extract (from grape pulp, skins, and seeds), green tea extract (with>95% polyphenols and >45% EGCG), reduced glutathione, N-Acetyl-L-Cysteine (NAC), R-lipoic acid, coenzyme forms of vitamin B2 (R5P) and vitamin B6 (P5P), and selenium.

    Below we will discuss each ingredient and show some of the research that confirms its effectiveness.

    VITAMIN C

    Vitamin C typically is called l-ascorbic acid or ascorbate and is an essential nutrient for humans and other animal species. The term "vitamin C" refers to a number of vitamins that have vitamin C activity in animals, including ascorbic acid and its salts (e.g., magnesium ascorbate, calcium ascorbate, sodium ascorbate, etc.), and some oxidized forms such as dehydroascorbate and semidehydroascorbate.

    Vitamin C is known to perform many critical functions within the body involving detoxification, tissue building, immune enhancement, pain control, and controlling or killing pathogenic organisms. It is also known to be helpful for wound and bone healing, healthy skin and eyes, fighting infections, stress control, toxic exposure, and repairing damaged tissue of all types. For much more information on the many benefits of Vitamin C see our blog article Vitamin C – An Amazing Nutrient.

    Below are two abstracts that show some of the beneficial effects of Vitamin C when used with other network antioxidants:

    ABSTRACT 1:
    Exhaustive physical exercise causes oxidation of glutathione status in blood: prevention by antioxidant administration.
    Sastre J,   Asensi M,   Gasco E,   Pallardo FV,   Ferrero JA,   Furukawa T,     Vina J
    In: Am J Physiol (1992 Nov) 263(5 Pt 2):R992-5

    We have studied the effect of exhaustive concentric physical exercise on glutathione redox status and the possible relationship between blood glutathione oxidation and blood lactate and pyruvate levels. Levels of oxidized glutathione (GSSG) in blood increase after exhaustive concentric physical exercise in trained humans. GSSG levels were 72% higher immediately after exercise than at rest. They returned to normal values 1 h after exercise. Blood reduced glutathione (GSH) levels did not change significantly after the exercise. We have found a linear relationship between GSSG-to-GSH and lactate-to-pyruvate ratios in human blood before, during, and after exhaustive exercise. In rats, physical exercise also caused an increase in blood GSSG levels that were 200% higher after physical exercise than at rest. GSH levels did not change significantly. Thus, both in rats and humans, exhaustive physical exercise causes a change in glutathione redox status in blood. We have also found that antioxidant administration, i.e., oral vitamin C, N-acetyl-L- cysteine, or glutathione, is effective in preventing oxidation of the blood glutathione pool after physical exercise in rats.

    ABSTRACT 2:
    The effect of glutathione and vitamins A, C, and E on acute skin flap survival.

    Hayden RE,   Paniello RC,   Yeung CS,   Bello SL,   Dawson SM
    In: Laryngoscope (1987 Oct) 97(10):1176-9

    Vitamins A, C, and E act as antioxidants and as free radical scavengers in biological systems. Glutathione is involved in several reactions in vitamin metabolism and also plays an important role in cell membrane protection against lipid peroxidation by free radicals. We sought to use these natural defense mechanisms against oxygen free radicals formed during reperfusion of ischemic skin flaps. An acute axial random skin flap model was utilized in the rat. Vitamins or glutathione were administered by oral gastric tube or intravenously in the perioperative period, and survival of the flap was measured at 1 week. Glutathione, beta-carotene, ascorbic acid and alpha-D- tocopherol showed mean flap survival of 84% to 89%, each of which was significantly improved over saline controls (67% p less than .0005). The mechanisms and biochemistry of these vitamins, and their interactions with other vitamins and with glutathione, are discussed, along with clinical implications of free radical scavenging and skin flap survival.

    GRAPE EXTRACT

    Grape extract (seeds, skin, pulp) contain highly bioavailable bioflavonoid complexes that in research studies have been shown to have powerful antioxidant capability. The Oligomeric Proanthocyanidins (OPCs) in grape seed extract are able to strengthen collagen fibers in aging or damaged connective tissue and can act as a preventative against connective tissue degradation.

    Some research indicates that anthocyans, which are found in extracts of grape skin and stems (but not in grape seed extract), can reduce oxidized glutathione while at the same time become reduced themselves. In addition, extracts of grape skin and stems (but not those of grape seed extract) contain a material called trans-resveratrol that has been shown to have chemopreventive effects.

    Below we have provided some of the abstracts that are included in our broad list of relevant abstracts for PRO-C.

    ABSTRACT 3:
    Protective effects of grape seed proanthocyanidins and selected antioxidants against TPA-induced hepatic and brain lipid peroxidation and DNA fragmentation, and peritoneal macrophage activation in mice.
    Bagchi D,   Garg A,   Krohn RL,   Bagchi M,   Bagchi DJ,   Balmoori J,     Stohs SJ
    In: Gen Pharmacol (1998 May) 30(5):771-6

    1. The comparative protective abilities of a grape seed proanthocyanidin extract (GSPE) (25-100 mg/kg), vitamin C (100 mg/kg), vitamin E succinate (VES) (100 mg/kg) and beta-carotene (50 mg/kg) on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced lipid peroxidation and DNA fragmentation in the hepatic and brain tissues, as well as production of reactive oxygen species by peritoneal macrophages, were assessed. 2. Treatment of mice with GSPE (100 mg/kg), vitamin C, VES and beta-carotene decreased TPA-induced production of reactive oxygen species, as evidenced by decreases in the chemiluminescence response in peritoneal macrophages by approximately 70%, 18%, 47% and 16%, respectively, and cytochrome c reduction by approximately 65%, 15%, 37% and 19%, respectively, compared with controls. 3. GSPE, vitamin C, VES and beta-carotene decreased TPA-induced DNA fragmentation by approximately 47%, 10%, 30% and 11%, respectively, in the hepatic tissues, and 50%, 14%, 31% and 11%, respectively, in the brain tissues, at the doses that were used. Similar results were observed with respect to lipid peroxidation in hepatic mitochondria and microsomes and in brain homogenates. 4. GSPE exhibited a dose-dependent inhibition of TPA- induced lipid peroxidation and DNA fragmentation in liver and brain, as well as a dose-dependent inhibition of TPA-induced reactive oxygen species production in peritoneal macrophages. 5. GSPE and other antioxidants provided significant protection against TPA-induced oxidative damage, with GSPE providing better protection than did other antioxidants at the doses that were employed.

    ABSTRACT 4:
    Clinical and capillaroscopic evaluation of chronic uncomplicated venous insufficiency with procyanidins extracted from vitis vinifera
    Costantini A,   De Bernardi T,   Gotti A
    In: Minerva Cardioangiol (1999 Jan-Feb) 47(1-2):39-46

    BACKGROUND: The pharmacological treatment of non-complicated chronic venous insufficiency is a current and well-debated topic. The introduction of new products with action on the venous system, improved knowledge on the physiopathology of venous insufficiency and the possibility provided by new analytical instruments, have given new impulse to the consolidation of the clinical value of phlebotonics in this indication. METHODS: In light of this, 24 patients with non-complicated chronic venous insufficiency were treated with oral administration of Oligomeric Proanthocyanidins (Pycnogenols-OPC) 100 mg/day. To evaluate the therapeutic efficacy of the treatment, an instrumental evaluation by optical probe capillaroscope was employed in addition to the traditional subjective clinical parameters: swelling, itching, heaviness and pain. The videocapillaroscope examination was performed at the lower third of the leg and the first toe. Edema in the capillaroscopic field, the number of observable capillaries and the capillary dilatation were the parameter chosen to evaluate the efficacy of treatment. All patients completed the study with no reports of adverse events during the period of observation. RESULTS: The results obtained show a positive clinical response (improved or absent symptoms) in over 80% of patients, with significant improvement of symptoms already evident after the first 10 days of treatment. The mechanism of action of the OPCs explains the rapid reduction of the swelling of the lower limbs and correlated with this are the other evaluable symptoms: heaviness and itching. Particularly striking results were observed for itching and pain which completely disappeared during the course of therapy in 80% and 53% of the patients respectively. Noteworthy is the good correlation between the clinical and instrumental data, with improvement in a total of 70% of patients. CONCLUSIONS: The results obtained in the course of this clinical experience, with evident improvement already during the first weeks of treatment, the absence of adverse events added to the benefit of a once-a-day administration, justify the use of OPC in the treatment of non-complicated chronic venous insufficiency.

    Nuclear factor erythroid 2-related factor 2 (Nrf2) is an important transcription factor that regulates antioxidant response element (ARE)-driven phase II detoxification enzymes. In this study, induction of phase II enzymes via Nrf2/ARE activation in the cytoprotective effect of crude polyphenol extract (CPE), oligomeric procyanidin fraction (OPF), and polymeric procyanidin fraction (PPF) from defatted grape seeds in HepG2 cells was evaluated. Among these treatments, the treatment with PPF significantly increased Nrf2 protein expression in the nuclear fraction. Treating the samples increased heme oxygenase-1 (HO-1) and NAD(P)H:quinone oxidoreductase 1 (NQO1) protein expression in a dose-dependent manner, and PPF significantly increased the levels of phase II enzymes. Cellular generation of reactive oxygen species (ROS) were effectively reduced by PPF. These results suggest that pretreatment with PPF shows a cytoprotective effect by inhibiting ROS production and inducing HO-1 and NQO1 expression via Nrf2 activation in HepG2 cells.

    GREEN TEA EXTRACT

    Green tea extract is obtained from the unfermented leaves of Camellia sinensis for which numerous biological activities have been reported including: antimutagenic, antibacterial, hypocholesterolemic, antioxidant, and protective against tumorigenesis. Below we have selected a few of the many abstracts we have on file showing the benefit of green tea extract.

    Enhancement of antioxidant and phase II enzymes by oral feeding of green tea polyphenols in drinking water to SKH-1 hairless mice: possible role in cancer chemoprevention.
    Khan SG,   Katiyar SK,   Agarwal R,   Mukhtar H
    In: Cancer Res (1992 Jul 15) 52(14):4050-2

    Following the oral feeding of a polyphenolic fraction isolated from green tea (GTP) in drinking water, an increase in the activities of antioxidant and phase II enzymes in skin, small bowel, liver, and lung of female SKH-1 hairless mice was observed. GTP feeding (0.2%, w/v) to mice for 30 days significantly increased the activities of glutathione peroxidase, catalase, and quinone reductase in small bowel, liver, and lungs, and glutathione S-transferase in small bowel and liver. GTP feeding to mice also resulted in considerable enhancement of glutathione reductase activity in liver. In general, the increase in antioxidant and phase II enzyme activities was more pronounced in lung and small bowel as compared to liver and skin. The significance of these results can be implicated in relation to the cancer chemopreventive effects of GTP against the induction of tumors in various target organs.

    INHIBITORY EFFECT OF SIX GREEN TEA CATECHINS AND CAFFEINE ON THE GROWTH OF FOUR SELECTED HUMAN TUMOR CELL LINES.
    In: Anticancer Drugs (1996 Jun) 7(4):461-8
    Institutional address: Department of Pharmacology and Toxicology College of Pharmacy University of Arizona Tucson 85721 USA.

    Green tea is an aqueous infusion of dried unfermented leaves of Camellia sinensis (family Theaceae) from which numerous biological activities have been reported including antimutagenic, antibacterial, hypocholesterolemic, antioxidant, antitumor and cancer preventive activities. From the aqueous-alcoholic extract of green tea leaves, six compounds (+)-gallocatechin (GC), (-)-epicatechin (EC), (-)- epigallocatechin (EGC), (-)-epicatechin gallate (ECG), (-)- epigallocatechin gallate (EGCG) and caffeine, were isolated and purified. Together with (+)-catechin, these compounds were tested against each of four human tumor cells lines (MCF-7 breast carcinoma, HT-29 colon carcinoma, A-427 lung carcinoma and UACC-375 melanoma). The three most potent green tea components against all four tumor cell lines were EGCG, GC and EGC. EGCG was the most potent of the seven green tea components against three out of the four cell lines (i.e. MCF-7 breast cancer, HT-29 colon cancer and UACC-375 melanoma). On the basis of these extensive in vitro studies, it would be of considerable interest to evaluate all three of these components in comparative preclinical in vivo animal tumor model systems before final decisions are made concerning which of these potential chemopreventive drugs should be taken into broad clinical trials.

    GLUTATHIONE AND N-ACETYL-L-CYSTEINE (NAC)

    Glutathione and NAC (a major precursor of glutathione) both provide important protection against toxins and free radicals, and can strengthen the immune system. Glutathione is considered to be one of the most important protective substances in the human body with almost 60% of liver detoxification accounted for by this key substance. In addition, glutathione is one of the most potent anti-viral substances known.

    Some research has indicated that glutathione may not be able to enter easily into certain types of cells, but NAC is able to enter these cells and be converted into glutathione once inside the cell. Thus, the combination of glutathione and NAC appear to be more potent than either alone.

    Below we provide some of the key abstracts we have on file regarding glutathione and NAC

    GSH rescue by N-acetylcysteine.
    Ruffmann R Wendel A
    In: Klin Wochenschr (1991 Nov 15) 69(18):857-62

    Reduced glutathione (GSH) is the main intracellular low molecular weight thiol. GSH acts as a nucleophilic scavenger and as an enzyme-catalyzed antioxidant in the event of electrophilic/oxidative tissue injury. Therefore, GSH has a major role as a protector of biological structures and functions. GSH depletion has been recognized as a hazardous condition during paracetamol intoxication. Conversely, GSH rescue, meaning recovery of the protective potential of GSH by early administration of N-acetylcysteine (NAC), has been found to be life-saving. Lack of GSH and electrophilic/oxidative injury have been identified among the causes of the adult respiratory distress syndrome (ARDS), idiopathic pulmonary fibrosis (IPF), and the acquired immunodeficiency syndrome (AIDS). Experimental and early clinical data (in ARDS) point to the role of NAC in the treatment of these conditions. Recently, orally given NAC has been shown to enhance the levels of GSH in the liver, in plasma, and notably in the bronchoalveolar lavage fluid. Rescue of GSH through NAC needs to be appreciated as an independent treatment modality for an array of different disease, all of which have one feature in common: pathogenetically relevant loss of GSH.

    Cysteine and glutathione concentrations in plasma and bronchoalveolar lavage fluid after treatment with N-acetylcysteine.
    Bridgeman MM Marsden M MacNee W Flenley DC Ryle AP
    In: Thorax (1991 Jan) 46(1):39-42

    N-acetylcysteine (600 mg/day) was given to patients by mouth for five days before bronchoscopy and bronchoalveolar lavage to determine whether N-acetylcysteine could increase the concentrations of the antioxidant reduced glutathione in plasma and bronchoalveolar lavage fluid. Bronchoalveolar lavage was performed 1-3 hours (group 2, n = 9) and 16-20 hours (group 3, n = 10) after the last dose of N-acetylcysteine and the values were compared with those in a control group receiving no N-acetylcysteine (group 1, n = 8). N-Acetylcysteine was not detected in plasma or lavage fluid. Plasma concentrations of cysteine, the main metabolite of N-acetylcysteine and a precursor of reduced glutathione, were greater in the groups receiving treatment (groups 2 and 3) than in group 1. Cysteine concentrations in lavage fluid were similar in the three groups. Concentrations of reduced glutathione were greater in both plasma and lavage fluid in group 2 than in group 1. These data suggest that N-acetylcysteine given by mouth is rapidly deacetylated to cysteine, with resulting increases in the concentrations of cysteine in plasma and of reduced glutathione in plasma and the airways, which thus temporarily increase the antioxidant capacity of the lung.

    R-LIPOIC ACID / ALPHA-LIPOIC ACID

    R-Lipoic Acid is normally made at low levels in the human body, where it functions primarily as an important metabolic nutrient in the conversion of pyruvic acid into acetyl coenzyme A. As such, it plays a crucial role in the metabolism of both fats and carbohydrates into energy. In addition, r-lipoic acid functions as an extremely powerful antioxidant capable of trapping many different types of free radicals in the body.

    Because it is both water and fat soluble, lipoic acid is able to operate in a broader range of body tissues than most other antioxidants. Its small size allows lipoic acid to enter areas of the body not easily accessible to many other substances; this allows lipoic acid, for example, to enter the cell nucleus and prevent free-radical damage to DNA.

    Because it is such a powerful antioxidant and can easily function as such in both a reduced and oxidized state, lipoic acid is able to protect other important antioxidants such as glutathione, Vitamin E, and Vitamin C. R-lipoic acid is also able to chelate heavy metals such as lead, cadmium, mercury, free iron, and free copper out of the body.

    Below we provide relevant scientific abstracts from our database regarding R-Lipoic acid.

    Alpha-Lipoic acid as a biological antioxidant.
    Packer L   Witt EH   Tritschler HJ
    In: Free Radic Biol Med (1995 Aug) 19(2):227-50

    alpha-Lipoic acid, which plays an essential role in mitochondrial dehydrogenase reactions, has recently gained considerable attention as an antioxidant. Lipoate, or its reduced form, dihydrolipoate, reacts with reactive oxygen species such as superoxide radicals, hydroxyl radicals, hypochlorous acid, peroxyl radicals, and singlet oxygen. It also protects membranes by interacting with vitamin C and glutathione, which may in turn recycle vitamin E. In addition to its antioxidant activities, dihydrolipoate may exert prooxidant actions through reduction of iron. alpha-Lipoic acid administration has been shown to be beneficial in a number of oxidative stress models such as ischemia-reperfusion injury, diabetes (both alpha-lipoic acid and dihydrolipoic acid exhibit hydrophobic binding to proteins such as albumin, which can prevent glycation reactions), cataract formation, HIV activation, neurodegeneration, and radiation injury. Furthermore, lipoate can function as a redox regulator of proteins such as myoglobin, prolactin, thioredoxin and NF-kappa B transcription factor. We review the properties of lipoate in terms of (1) reactions with reactive oxygen species; (2) interactions with other antioxidants; (3) beneficial effects in oxidative stress models or clinical conditions.

    ABSTRACT 11:
    Regeneration of glutathione by α-lipoic acid via Nrf2/ARE signaling pathway alleviates cadmium-induced HepG2 cell toxicity.
    Zhang J, Zhou X, Wu W, Wang J, Xie H, Wu Z.
    In: Environ Toxicol Pharmacol. 2017 Apr;51:30-37. doi: 10.1016/j.etap.2017.02.022. Epub 2017 Feb 27.

    Alpha-lipoic acid (α-LA) is an important antioxidant that is capable of regenerating other antioxidants, such as glutathione (GSH). However, the underlying molecular mechanism by which α-LA regenerates GSH remains poorly understood. The current study aimed to investigate whether α-LA regenerates GSH by activation of Nrf2 to alleviate cadmium-induced cytotoxicity in HepG2 cells. In the present study, we found that cadmium induced cell death by depletion of GSH through inactivation of Nrf2. Addition of α-LA to cadmium-treated cells reactivated Nrf2 and regenerated GSH through elevating the Nrf2-downstream genes γ-glutamate-cysteine ligase (γ-GCL) and GR, both of which are key enzymes for GSH synthesis. However, blocking Nrf2 with brusatol in the cells co-treated with α-LA and cadmium reduced the mRNA and the protein levels of γ-GCL and GR, thus suppressed GSH regeneration by α-LA. Our results indicated that α-LA activated Nrf2 signaling pathway, which upregulated the transcription of the enzymes for GSH synthesis and therefore GSH contents to alleviate cadmium-induced cytotoxicity in HepG2 cells.

    SELENIUM

    Selenium has been shown by clinical research to be a key mineral in the body's defenses against free radicals and has been shown to be a major factor in reducing the symptoms of HIV infections and in the prevention of tumors. Selenium is used in conjunction with glutathione to form the powerful enzyme glutathione peroxidase that is responsible for detoxification of peroxides formed during the process of aerobic metabolism in humans and other animals.

    ABSTRACT 12
    Serum selenium concentrations in rheumatoid arthritis.
    In: Ann Rheum Dis (1991 Jun) 50(6):376-8

    O'Dell JR,   Lemley-Gillespie S,   Palmer WR,   Weaver AL,   Moore GF,     Klassen LW

    Selenium is a trace element and an essential part of the enzyme glutathione peroxidase, which protects cells from oxidative damage. Selenium has been shown to have antiproliferative, anti-inflammatory, antiviral, and immune altering effects. Serum selenium concentrations in 101 patients with seropositive rheumatoid arthritis were found to be significantly lower than those in 29 normal, healthy controls (mean (SD) 148 (42) v 160 (25) micrograms/l) and also lower than those in eight patients with fibrositis (148 (42) v 166 (25) micrograms/l). It is speculated that serum selenium concentrations may modulate the effect of viral or other infections in subjects with the appropriate genetic background and in this way enhance the development or progression of rheumatoid arthritis.

    ABSTRACT 13
    Studies on selenium in top athletes.
    Dragan I,   Ploesteanu E,   Cristea E,   Mohora M,   Dinu V,   Troescu VS
    In: Physiologie (1988 Oct-Dec) 25(4):187-90

    The authors performed a controlled trial in 18 top athletes (9 weight lifters and 9 rowers, girls) in order to make evident some chronic and acute effects (antioxidant) of selenium. Nonprotein--SH (essential glutathione), lipid peroxides (MDA-malondialdehyde), glucose-6-phosphate dehydrogenases (G-6-PDH) and fructose-1,6- diphosphate aldolase in serum, have been recorded initially on basal conditions, after 3 weeks of treatment (100 micrograms/day selenium or placebo) and again after 3 weeks of treatment, also on basal conditions, when crossing over the groups (between a free interval of 10 days). In another trial we registered these parameters on basal conditions and after two hours of hard training accompanied by a per oral administration of 150 micrograms selenium (respectively placebo). The results show significant changes under selenium treatment of the peroxides, G-6-PDH and light changes, not significant of the nonprotein--SH, changes which could suggest an antioxidant effect of this element.

    VITAMINS B2 and B6 IN COENZYME FORMS

    Vitamin B2 as coenzyme riboflavin-5-phosphate is a key vitamin that supports the regeneration of glutathione (via glutathione reductase).  Vitamin B6 as coenzyme pyridoxal-5-phosphate is a key vitamin that supports the ability of glutathione to combine with toxic substances (via glutathione transferase) in the process of eliminating them from the body. They are especially effective in their coenzyme forms which allows them to be directly utilized by the body starting in the intestinal tract.

    MAGNESIUM, CALCIUM, AND ZINC

    Magnesium, zinc, and calcium synergistically work with (and enhance the effects of) the other ingredients in PRO-C. Minerals are especially needed as active components of enzymes that drive metabolic activity. For example, magnesium is required in the functioning of more than 325 types of enzymes.

  • QUICKSILVER LIPOSOMAL FORMULAS - NEW PRODUCTS!

    Fred Liers PhD quicksilver liposomal formulasOne of the most significant developments for nutrient uptake and assimilation is the advent of liposomal delivery systems. Once in the range of 300–5,000 nanometers, the latest liposomes are now just 20–100 nanometers (nm)!

    The significance of these small liposomes—tiny bilayer lipid structures—is that there is a major increase in the amount of nutrient delivery to cells. That is, small liposomes show significantly greater efficiency at intracellular delivery of encapsulated compounds.

    quicksilver liposomal formulas

    Liposomal delivery systems have evolved rapidly and now offer major advantages over nutritional supplements delivered by standard means—like capsules, tablets, powders, and liquids (e.g., tinctures).

    Liposomal delivery systems first utilized multi-lamellar vesicles (MLV) ranging ins size from 300–5,000 nanometers. Later, "large" unilamellar vesicles (LUV) (100–300 nanometers) were developed. Products containing LUVs are more effectively assimilated than MLVs.

    As noted, lipsomal technologies have shrunk liposome sizes to 20–100 nanometers (nm), the category size for small unilamellar vesicles (SUV). This means the body can far more easily assimilate nutrients delivered liposomally when the particle sizes are up to 10 times smaller than already effective liposome sizes.

    Small liposomes (SUV) have a long circulation half-life and better cellular accumulation. Small lipid particles have the fastest uptake kinetics and can participate in paracellular (between cells) transport. The nutritional liposome industry is rapidly moving toward the use of small liposomes.

    Key Point: Small liposomes (SUV) are significantly more efficient at intracellular delivery of encapsulated compounds. In a recent study with carefully sized liposomes, cellular uptake increased nine-fold as liposome size was decreased from 236 nm to 97 nm and was 34 fold higher at 64 nm.

    Nutrients that can be delivered liposomally range from vitamin C and glutathione to many types of adaptogenic and medicinal herbs.

    Benefits of Liposomal Delivery

    • Rapid update, assimilation, and movement into cells
    • Oral intake bypasses digestive system—nutrients go directly into body
    • High levels of nutrients assimilated
    • Reduced dosages and less "wasted" product
    • Nutrients penetrate smallest compartments in the body
    • Nutrients circulate widely
    • Precise intra-oral delivery
    • Simple manual pump from glass bottle
    • Easy water dispersability when desired
    • Good tasting!

    Liposomal delivery systems are the future of nutritional supplements given all the advantages they confer. HPDI recognizes the value of liposomal products, and now offers the best formulas available—from Quicksilver Scientific, Inc.—to resellers.

    QUICKSILVER LIPOSOMAL FORMULAS

    HPDI offers four liposomal formulas from Quicksilver Scientific, the leader in nanoliposomal delivery systems. Each formula offers unparalleled uptake and assimilation—and good taste!—via intra-oral delivery. These products include:

    Quicksilver liposomal formulas HPDI offers four liposomal formulas from Quicksilver Scientific.

    Liposomal Vitamin C with R-Lipoic Acid (mean size 50–100nm): Quicksilver Scientific’s Etheric Delivery™ system for Liposomal Vitamin C (with R-Lipoic Acid) is the most absorbable form of professional-grade Vitamin C. Vitamin C is essential to any detoxification program because it feeds the system that eliminates toxins. It is also very effective in removing lead and other heavy metals from our system and fighting off the free radicals that form in the liver during the first phase of detoxification.

    R-Lipoic Acid (as sodium R-Lipoate) has an exceptionally well-documented ability to upregulate the glutathione system via the Nrf2 nuclear transcription pathway. This combination of liposomal vitamin C and R-Lipoate in a nanoliposomal delivery system potently harnesses the potential of Vitamin C to the power of a fully functioning glutathione system.

    The absorption of conventional oral Vitamin C diminishes rapidly as the dose increases (e.g., about 19% for 1000 mg oral vitamin C). Nanosphere delivery greatly increases absorption and for some compounds can provide higher intracellular delivery than an IV administration.

    Quicksilver Vitamin C Quicksilver Liposomal Vitamin C with R-Lipoic Acid

    Suggested Usage: General use for antioxidant and detoxification function, take eight pumps per day (1,000 mg of Vitamin C and 50 mg of R-Lipoate). For advanced intermittent use, use up to 50 pumps per day (6,250 mg Vitamin C and 312.5 mg R-Lipoate) or more, in divided doses throughout the day. For detoxification protocols, especially with metal toxicities, build dosage gradually, starting from low doses, as they are tolerated. If strong detoxification reactions are observed, back off dosage. Children should start at approximately 1/4 of adult (two pumps per day) dosage and work up. For topical application, one pump can cover the face for a daily treatment, or use several pumps as a mask and leave on for 10–15 minutes; skin can be re-wetted and left for another 10 minutes before rinsing off excess.

    Liposomal Glutathione: Quicksilver’s Phospholipid Encapsulation Etheric Delivery system protects glutathione from digestive enzymes that otherwise inhibit absorption of oral glutathione supplementation. In cell cultures, liposomal products have demonstrated over 100 times more efficiency for intracellular delivery than IV-based liposomal glutathione.

    Quicksilver's Liposomal Glutathione comes with a precision pump to accurately deliver 50 mg of reduced glutathione and 68 mg of injectable-grade essential phospholipids (derived from sunflower oil) per pump. The patent-pending process, plus a natural lemon flavoring, allows this product to be taken intra-orally for maximum absorption without the foul sulfur taste typical of liposomal glutathione products. The formula can be taken every 3–4 hours for even delivery throughout the day. One bottle delivers 100, 0.5 ml doses.

    Quicksilver Liposomal Glutathione Quicksilver Liposomal Glutathione with Lemon Mint

    Suggested Usage: For general antioxidant and detoxification protection, use eight pumps per day (400 mg glutathione). For advanced protection, use up to 20 per day (1,000 mg glutathione) or more, in divided doses throughout the day. For large doses, take two pumps at a time to allow for maximum oral absorption, and hold at least 30 seconds before swallowing. Children should start at approximately 1/4 of adult (two pumps per day) dosage and work up.

    Liposomal Colorado Hemp Oil: This product uses non-THC (<0.3%) cannabidiol (CBD) from all-natural Colorado Hemp Oil. CBD is the non-psychoactive part of the industrial hemp plant. Quicksilver Scientific’s liposomal delivery of Nanoemulsified Colorado Hemp Oil far outpaces tinctures and is faster, stronger and more effective. Cannabidiol interacts with our body’s naturally occurring cannabinoid receptors to aid with pain relief and enhanced feelings of well being. The advanced technology behind this groundbreaking liquid delivery method makes for precise dosing and immediate effect.

    Because of the known interaction of CBD with these cannabidiol receptors, much new research has focused on CBD’s receptor-mediated neuro-protective, antiemetic, and analgesic properties, and of its effect on mood and other aspects of mental health.

    New research on gene transcription modulation offers an even deeper look into the biochemical mechanisms at work when ingesting CBD. Research in this vein has shown more than 1,000 genes that are differentially upregulated by CBD (a more than ten-fold increase than those affected by THC). In general, the effects increased cell stress responses—including antioxidant-defense and detoxification genes (mainly via EhRE/ARE-Nrf2 induction)—and downregulated many inflammation-mediating genes. These effects combined with CBDs NMDA-receptor-stabilizing effects, show great promise for its use in calming the neuro-inflammatory responses accompanying neurotoxic and chronic illness states.

    Quicksilver Nanoemulsified Colorado Hemp Oil Nanoemulsified Colorado Hemp Oil

    Suggested Use: Take 1–4 pumps by mouth, holding for 30 seconds before swallowing. Repeat if needed. Four pumps contain 30 mg of Hemp Extract (aerial parts) and 12 mg of Phytocannabinoid Diols. There are 25 four-pump servings per container. Best taken on an empty stomach 10 minutes before meals. May be stirred into a small amount of water. Once opened, use within 60 days. Store at room temperature and away from light.

    Liposomal NanoMojo (adaptogenic blend): Dr. Christopher Shade, PhD of Quicksilver Scientific, collaborated with master herbalist Dan Moriarty of Sun Horse Energy to create NanoMojo, a groundbreaking functional medicine product. By combining Moriarty’s unique adaptogenic formulation with Dr. Shade's state-of-the-art liposomal encapsulation, they’ve overcome the limitations of poor oral adsorption and made the phytochemicals quickly available at the cellular level. This new innovative blend of adaptogens from around the world is maximized for effectiveness.

    Adaptogens are non-toxic phytochemicals that help the body achieve homeostatic balance under adverse conditions that would typically be associated with sympathetic (fight or flight) reactions. They help regulate natural harmony, adrenal balance, and stress accommodation (resistance to stress). In fact, adaptogenic herbs have been used in Ayurvedic medicine for more than 4,000 years and Chinese medicine for nearly 3,000 years to increase energy (chi) and concentration.

    Scientific literature reports that adaptogenic herbs play significant roles in decreasing markers of stress-activated protein kinases, cortisol, and nitric oxide. These markers indicate a lowered level of systemic stress and inflammation and decreased symptoms of an over-taxed adrenal system.

    NanoMojo contains the following adaptogenic herbs: Açaí, Lyceum (Goji) fruit, Gynostemma (Jiaogulan) (aerial parts), American Ginseng (root), Siberian Ginseng (root), Schisandra (fruit), Licorice (root), Rhodiola (root), Astragalus (root), Reishi (fruiting body), Catuaba (bark), Stinging Nettle (aerial parts), Saw Palmetto (fruit), Guarana (seed), Ashwagandha (root), Tribulus (aerial parts), Epimedium (aerial parts), Yohimbe (bark), and Organic Maple (sap) syrup.

    NanoMojo helps your body adapt to the various conditions that cause stress, something most of us experience daily. This liposomal formulation is the culmination of more than eight years of research and development. Not only is it effective, but it also tastes very good.

  • HOMOCYSTEINE GENETICS – COENZYME B VITAMINS

    Dr. Hank Liers, PhD homocysteine coenzyme B vitaminsWe previously published an article titled FOLATE INGREDIENTS – FOLINIC ACID & 5-MTHF in which we discuss how coenzyme folate vitamins are far superior to the synthetic folic acid form. In today's article, I take a more in-depth look at how homocysteine is formed from methionine, how genetics affects the metabolic pathways, and how B vitamins are used in metabolic pathways.

    One way to look at the metabolic pathways of methionine (an essential amino acid) is that it provides a way for the body to convert this sulfur containing amino acid either to cysteine and its key by-products glutathione, taurine, and sulfates or allows remethylation back to methionine to occur using either the Folate Cycle or the Trimethyl glycine (betaine) pathways.

    Figure 1 shows these metabolic pathways including the vitamins required at each step including vitamin B6 (as P-5-P), methylcobalamin, and 5-methyltetrahydrofolate (5-MTHF). In addition, it shows the key enzymes produced by the body at each step. These enzymes include CBS (cystathione beta synthase), BHMT (betaine homocysteine methyltransferase), MS (methionine synthase), and MTHFR (methylene tetrahydrofolate reductase).

    HEALTH ISSUES ASSOCIATED WITH HIGH HOMOCYSTEINE LEVELS

    It is highly important that the various metabolic pathways function correctly to keep homocysteine at healthy levels (6–8 µmol/L). Unfortunately, high levels of homocysteine in the body (10–20 µmol/L) are a factor in a wide range of health issues, including:

    • Greater risk for heart problems, including coronary artery disease, heart attacks, stroke, high blood pressure, congestive heart failure, and abnormal cholesterol levels. This is due to increased inflammation, sometimes due to blood clotting spontaneously, and because of blockages of the major arteries.
    • Mental abnormalities such as depression, anxiety, bipolar disorder, and other mental problems are more common among people with high homocysteine
    • Migraines and headaches in a significant percentage of the population
    • In those who suffer from high homocysteine due to having nutritional deficiencies anemia, aches and pains, hearing loss, age-related macular degeneration (ARMD), slowed development, and birth defects might also be possible
    • Greater risk for dementia, Alzheimer’s disease, brain atrophy, and other cognitive problems
    • In children, skeletal and developmental abnormalities including having a curved spine or protruding chest and rib cage. Some patients appear very tall and thin, and some might also have very long, thin “spider-like” toes and fingers.
    • Behavioral problems, including ADHD, autism and other learning disabilities

    ROLE OF GENETICS IN HOMOCYSTEINE METABOLISM

    Ten or more years ago, questions of how genetics enters into homocysteine metabolism were unlikely to be asked. However, in recent years DNA testing has advanced and is now available to everyone (for example, see my article about Bodysync's genetic test, GET STARTED – NUTRIGENOMIC TESTING.

    You may have heard a great deal about MTHFR (methylene tetrahydrofolate reductase). This gene is involved in folate metabolism and has a central role in methylation processes like repair of and building new DNA in dividing cells.

    In the remethylation pathway for conversion of homocysteine to methionine, MTHFR plays a key role in converting folate into 5-MTHF which is needed along with B12 as methylcobalamin in order for the conversion to take place. Genetic variations in MTHFR have been studied in depth. Of the many variations studies the most significant ones appear to be variations of C677C such as C677T (referred to as heterozygous) or T677T (referred to as homozygous). The heterozygous variant appears in about 30–50% of the population and causes somewhat less efficiency in the conversion of folic acid to 5-MTHF. However, the homozygous variation occurs in about 10% of the population and can have serious effects due to converting little homocysteine back to methionine.

    Another variation in MTHFR is called A1298A. These variations are A1298C and C1298C and will have similar effects to the C677C variations. It was interesting to me when I recently analyzed my Bodysync genetic test results showing I carry the variation A1298C (heterozygous), which indicates I may not be effectively converting homocysteine back to methionine.

    Additionally, my Bodysync genetic test results also indicate that I have heterozygous variations in the CBS enzyme shown in Figure 1, as well as heterozygous variations in MTR and MTRR enzymes, which are involved with B12 levels in the  remethylation pathway. These results indicate that I need to take higher levels of methylcobalamin and 5-MTHF.

    IMPORTANCE OF COENZYME FORMS AND PROPER AMOUNTS OF B VITAMINS

    Many of the B vitamins on the market today unfortunately are in synthetic form. The body can only use the natural coenzyme forms effectively. For example, the body needs vitamin B6 in the form of P-5-P (pyridoxal-5-phosphate), folate in the form of L-5-MTHF, and B12 in the form of methylcobalamin for proper metabolism of methionine. In some cases the body can use the synthetic forms of pyridoxine HCl, folic acid, and cyanocobalamin but pays a cost (e.g., in time and energy) by having to convert synthetic forms to coenzyme forms.

    Add to the prevalence of synthetic B vitamins, the fact that genetic deficiencies are more common than previously assumed, and it becomes clear that the coenzyme forms of B vitamins in the proper amounts are extremely important.

    Fortunately, I have always believed it best to include as many coenzyme forms as possible in the nutritional supplements I formulate (over the past 27 years). For example, all HPDI multivitamins include coenzymes of B1, B2, B6, B12, and folate (as 5-MTHF and folinic acid). This is uncommon in most multivitamin formulas on the market. For this reason our supplements are ideally suited to the prevention or resolution of most genetic problems regarding homocysteine.

    In addition, I have always chosen to include higher amounts than most multivitamins on the market. We also make available 5-MTHF one milligram (1 mg) capsules and methylcobalamin five milligram (5 mg) sublingual tablets. When genetic variations are in play as discussed above, then providing relatively higher amounts of coenzyme B vitamins that support important requirements in the body seems necessary.

    Interestingly, several other nutrients are involved in the pathways involving methionine and homocysteine. These include zinc, magnesium, and Vitamin B2. Our multivitamin formulas and magnesium formulas, especially Myo-Mag with its coenzyme B1, B2, and B6, are recommended to support these nutrient needs. Finally, it has been found that N-Acetyl-L-Cysteine (NAC) can significantly lower homocysteine (by up to 50%), most likely because its gives the body an excellent source of cysteine without have to use methionine.

    SUMMARY

    In this article, I have shown the value of the use of genetic testing and high-quality coenzyme B vitamins in resolving health issues associated with high values of homocysteine in the body.

  • RECENT ADVANCES IN LIPOSOME TECHNOLOGY

    Dr. Hank Liers, PhD liposomes liposomal nutrientsHealth Products Distributors, Inc. recently decided to augment the variety of liposomal products we carry based upon the significant advancements of the technology during the last few years.

    Among the benefits of using liposomes are that significantly higher levels of certain nutrients can be delivered directly to the cells where they are needed. In this article, I will discuss some of the recent scientific advances and new products associated with these advances.

    Types of Liposomes Figure 1 - liposomal types

    SMALLER IS SIGNIFICANTLY BETTER

    In December 2015, I wrote a blog article on liposomes to introduce the liposomal products we began selling at that time. Unfortunately, the particle size of these original products are on the order of 500 nanometers (nm), and as such are not nearly as well absorbed as the much smaller liposomes that have recently been developed by Quicksilver Scientific.

    Figure 1 gives an overview of current liposome types. These include multi-lamellar vesicles (MLV) that range in size from 300–5,000 nm and have more than one bilayer.

    Large unilamellar vesicles (LUV) range in size from 100–300 nm. They have a single bilayer and a high trapped volume, but have lower thermodynamic stability and decreased uptake.

    Small unilamellar vesicles (SUV) range in size from 20–100 nm. SUV have a long circulation half-life and better cellular accumulation. Small lipid particles have the fastest uptake kinetics and can participate in paracellular (between cells) transport. The nutritional liposome industry is moving toward the use of SUV.

    Small liposomes (SUV) are drastically more efficient at intracellular delivery of encapsulated compounds. In a recent study with carefully sized liposomes, cellular uptake increased nine-fold as liposome size was decreased from 236 nm to 97 nm and was 34 fold higher at 64 nm (see Figure 2). This figure shows flow cytometry results (a measure of cellular uptake) for Caco-2 cells incubated with liposomes containing Dil-C18 at 15 min and 60 min intervals.

    HPDI CARRIES NEW LIPOSOMAL PRODUCTS

    Our new liposomal product supplier currently is providing a wide range of products that have stable liposomes of about 50 nm. These products are bottled in such a way that they are taken by pumping (or squirting) the contents directly into your mouth (i.e., oral administration). This is an extremely clean method of dosing in which a few pumps of liposomal liquid can be rapidly taken or administered with no need for placing the product into separate glass of water or squeezing packets.

    Because of the very small size much of the ingredients are absorbed through mucus membranes and into the system and cells extremely quickly (within seconds/minutes). In addition to the ingredients within the liposome, one gets significant amounts of phosphytidal choline into the cell membranes with a very beneficial effect on membrane function.

    We are currently carrying the following Quicksilver Scientific liposomal products:

    1. Vitamin C with R-Lipoic Acid
    2. Glutathione
    3. Colorado Hemp Oil
    4. NanoMojo - a unique combination of 19 adaptogenic herbs

    Quicksilver Liposomes

    We highly encourage that you use the products because of the huge benefits they provide. We use them ourselves every day.
