VITAMIN D3 PLUS – CRITICAL UPDATE

Dr. Hank Liers, PhD vitamin d3 plusFred Liers PhD vitamin d3 plusThe scientific evidence for Vitamin D3 continues piling up. It is abundantly clear a large percentage of the global population is deficient in Vitamin D3, and that supplements can make a huge difference for people to avoid and prevent deficiency of this critical nutrient.

During a period when people are self-isolating and mostly indoors—and there is an immediate coronavirus threat—it is time to act on the science supporting Vitamin D3.

It is now well known that Vitamin D plays critical roles in fighting viruses and building immunity. Many doctors now routinely advise patients to take high doses of Vitamin D3, especially in the winter when both Vitamin D levels and sun exposure are lowest.

“I have found the value of bolstering immune function with Vitamin D to be incredibly powerful.” – Dr. Jeffery Rutersbusch

William Grant, PhD, says: “Coronaviruses cause pneumonia as does influenza. A study of the case-fatality rate from the 1918-1919 influenza pandemic in the United States showed that most deaths were due to pneumonia. The SARS-coronavirus and the current China coronavirus were both most common in winter, when vitamin D status is lowest.” [1–5]

VITAMIN D3 PLUS

VITAMIN D3 PLUS is HPDI’s complete vitamin D3 formula. It was designed by Hank Liers, PhD to not only provide Vitamin D3, but also Vitamin K2 and Vitamin A both of which support the body’s uptake and use of Vitamin D3.

We have covered Vitamin D3 in previous posts such as Vitamin D3 Superstar! and Vitamin D3 for Health, and various other articles. In fact, Dr. Hank formulated Vitamin D3 PLUS 10 years ago, and it has become one of our best-selling products. As the general understanding that Vitamin D3 is critical for health increased, more people are taking action to supplement their diet with supplements like Vitamin D3 PLUS.

VITAMIN D3 PLUS is designed as an advanced Vitamin D formula providing high-dose Vitamin D3. Vitamin D3 is the natural form of Vitamin D produced in the body from sunlight and is the form best used for therapeutic purposes.

One softgel capsule of Vitamin D3 Plus provides 125 mcg (5,000 IU) of Vitamin D3 derived from highly purified and molecularly distilled fish liver oils. In addition, the product contains 300 mcg (1,000 IU) of Vitamin A also derived from highly purified and molecularly distilled fish liver oils and 10 mcg of Vitamin K2 from menaquinone-7.

Vitamin D3 Plus supplement

Vitamin D3 Plus includes synergistic nutrients known to enhance absorption and use of Vitamin D3 in the body. These nutrients include Vitamin K2 (menaquinone-7) (10 mcg), which which works together with Vitamin D to help boost bone density, improve cardiovascular health, and boost immunity.

Vitamin D3 Plus also provides 300 mcg (1,000 IU) of Vitamin A, a nutrient known to work powerfully with Vitamin D to help create optimal health. As dosages of Vitamin D increase, ideally your dosage of Vitamin A also will increase, and vice versa. The formula also includes natural Vitamin E as an antioxidant.

IMPORTANT VITAMIN D FACTS

  • In a world of sun avoidance, sun blocks, working indoors, latitudinal effects, etc., nearly the entire population suffers in multiple ways from Vitamin D3 deficiency
  • Human beings optimally produce 10,000–20,000 IU of Vitamin D3 (cholecalciferol) when exposed to full sunlight on a significant portion of skin for about 30 minutes
  • The body starts to gain the full benefits of Vitamin D3 only after it produces (or intakes orally) about 5,000 IU Daily
  • Vitamin D3 is a prehormone with powerful effects and with few exceptions cannot be obtained in sufficient amounts from diet

VITAMIN D3 PLUS FORMULATED FOR OPTIMAL HEALTH

Vitamin D3 is a fat-soluble vitamin increasingly known as a nutrient essential for health and well-being. Recent studies show that almost all body systems benefit from adequate Vitamin D intake/production. Therefore, it is important that the body receive optimal amounts in order to build the best health. In fact, recent studies indicate that 5,000 IU of Vitamin D3 is an ideal amount for daily intake. What is notable about this amount is that the body does not gain the full benefits from Vitamin D until it reaches this “threshold” level of about 5,000 IU. While the body stores Vitamin D, it must first be given an adequate supply.

Because Vitamin D3 is important for all body systems, the benefits of adequate Vitamin D are numerous. Adequate Vitamin D not only helps to ensure good health, but also supports the body in preventing and combating a wide range of conditions. When taken in adequate dosages (one or two 5,000 IU capsules daily), Vitamin D3 can provide the following benefits: 1) stronger bones, 2) enhanced immunity, 3) protection from autoimmune diseases, 4) improved blood sugar control, 5) normalized blood pressure, 6) prevention of tumors, 7) protection against flu, 8) better balance, 9) prevention of autism, 10) improved mood, 11) reduction of chronic pain, 12) improved dental health, 13) improved muscle strength, 14) prevention of birth defects, 15) improved prostate health, 16) better bowel health, 17) supports individuals with Multiple Sclerosis, 18) reduced symptoms of PMS, and 19) many other benefits.

The oils in Vitamin D3 Plus are emulsified by the addition of a non-GMO sunflower lecithin that ensures excellent uptake by the body. Vitamin E as tocopherols and tocotrienols derived from Oryza rice bran oil are included to protect against oxidation in the product and in the body. In addition, the rice bran oil is used to enhance the absorption of the fat-soluble Vitamin D and Vitamin A.

Vitamin D3 Plus may be taken with Hank & Brian’s Essential Fats Plus E. This combination is an ideal way to obtain essential fatty acids, Vitamin D, Vitamin A, Vitamin E, and Vitamin K2. Taking other Foundational Supplements provides additional benefits.

VITAMIN D DEFICIENCY IS EPIDEMIC WORLDWIDE

Vitamin D deficiency currently is a worldwide epidemic with more than one billion people at risk for diseases associated with low Vitamin D status. Vitamin D is proven safe and effective for a wide range of health conditions (see above and below). There are various reasons for this epidemic, including a significant portion of the world’s population living in northerly latitudes (where sunlight is inadequate during many months of the year), sun avoidance, time spent indoors, etc.

VITAMIN D3 MORE EFFECTIVE THAN D2

Vitamin D3 Plus provides only the Vitamin D3 form of Vitamin D. We avoid the use of Vitamin D2. Vitamin D2 has greater potential for toxicity, poorer absorption, and reduced effectiveness. Vitamin D3 is the preferred form of Vitamin D…and the form that gives you the best health.


VITAMIN D3 PLUS FROM HIGHLY PURIFIED FISH LIVER OIL

Vitamin D3 Plus provides Vitamin D3 from purified fish (cod) liver oil. Our formula comes in a softgel (instead of a standard capsule) for greater purity. In a softgel, the oil does not contain other ingredients (like cornstarch) commonly used to microencapsulate Vitamin D oil into powders used in capsule forms. The softgel form allows us to avoid using undesirable fillers and excipients. This means you avoid undesirable additives.

VITAMIN D3 PLUS OFFERS SUPERIOR ABSORPTION

Vitamin D3 PLUS includes non-GMO sunflower lecithin to act as an emulsifier of Vitamin D thereby ensuring effective absorption. In addition, the use of rice bran oil further supports absorption of fat-soluble Vitamin D. Optimizing absorption of Vitamin D is critical especially in cases of Crohn’s disease, Celiac disease (gluten intolerance), and irritable bowel syndrome. In these conditions, individuals often suffer from osteoporosis, kidney disease, etc. Better absorption means greater effectiveness.

NATURAL FORMS OF VITAMIN E PREVENT OXIDATION

Vitamin D3 PLUS includes Orzya rice bran oil because the fish liver oils in the formula are susceptible to oxidation. Oryza rice bran oil provides significant amounts of Vitamin E in the form of mixed tocotrienols and tocopherols, which are powerful antioxidants. These forms of Vitamin protect the product and keep Vitamin D3 Plus fresh, and act as powerful antioxidants in the body.

VITAMIN D3 PLUS INCLUDES VITAMIN A

Vitamin D3 Plus includes 300 mcg (1,000 IU) of Vitamin A along with Vitamin D3. We include Vitamin A because it is known that Vitamin A and Vitamin D act synergistically. Normal bone remodeling requires both Vitamin A and Vitamin D. In addition, when Vitamin D levels are inadequate, high dose Vitamin A may cause bone loss. However, no observed bone loss occurs when there are adequate levels of Vitamin D (more than 2,000 IU daily). Chris Masterjohn discusses the topic in his seminal article “Vitamin A on Trial: Does Vitamin A Cause Osteoporosis?” (see Weston A. Price Foundation website). Masterjohn states that Vitamin A taken in conjunction with Vitamin D is required for proper bone remodeling in the body. Vitamin A and Vitamin D not only act synergistically in the body, but also when taken together ensure protection from the effects of taking either one alone in high doses.

VITAMIN K2 REQUIRED FOR VITAMIN D FUNCTION

Vitamin D3 Plus includes 10 mcg of Vitamin K2 (the menaquinone-7 or MK-7 form) per softgel in our formula. Vitamin K2 (especially as MK-7) is necessary for the proper activation of bone matrix proteins by conferring on them the physical ability to bind calcium (i.e., to build strong bones). Research also shows that Vitamin K2 can help remove calcium from soft tissues in the body and instead put the calcium into bony structures (i.e., where it serves to build a strong skeletal system). Vitamin D3 Plus can help put the health-building powers of Vitamin K2 (as menaquinone-7) to work for optimal health.

Chris Masterjohn elegantly discusses the role of Vitamin K2 in bone formation in his groundbreaking article “On the Trail of the Elusive X-Factor: A Sixty-Two-Year-Old Mystery Finally Solved” (see Weston A. Price Foundation website). Because Vitamin K2 is needed to facilitate the function of Vitamin D in proper bone formation (including tooth structure), Masterjohn states that Vitamin D toxicity is most likely a case of Vitamin K2 deficiency. It is clear that adequate Vitamin K2 both protects against Vitamin D toxicity and supports the effective use of Vitamin D in the body.

In Health Benefits of Vitamin K-2: A Revolutionary Natural Treatment for Heart Disease and Bone Loss (2006), Larry Howard and Anthony Payne, PhD, assert that as little as 6 mcg (micrograms) of Vitamin K2 (as MK-7) can be beneficial. The half-life of Vitamin K2 (as MK-7) is about three days in the body. This means that as few as 6 mcg of Vitamin K2 is beneficial because the levels increase by a factor of three when its taken regularly.

It is notable that Vitamin K2 is found naturally in fermented foods, including some cheeses, sauerkraut, natto (i.e., a traditional Japanese dish of fermented soybeans), and in dairy products, eggs, and certain meats. However, the vast majority of individuals in the world do not receive adequate amounts of Vitamin K2 from their diets. Now anyone can gain the important benefits of Vitamin K2 along with the benefits of Vitamin D and Vitamin A by taking Vitamin D3 Plus.

Vitamin D is known as the sunshine vitamin.

VITAMIN D3 PLUS
NUTRITIONAL CONSIDERATIONS
AND APPLICATIONS

Vitamin D, calciferol, is a fat-soluble vitamin. It is found naturally in some animal foods, but also can be made in the body after exposure to ultraviolet rays from the sun. It is known that season, latitude, time of day, cloud cover, smog, and use of sunscreens affect UV ray exposure. For example, in northern areas of the US the average amount of sunlight from November through February is insufficient to produce significant Vitamin D synthesis in the skin. Sunscreens with a sun protection factor (SPF) of 8 or greater will block UV rays that produce Vitamin D even in regions of the US where sunlight is plentiful.

MINERAL METABOLISM

The liver and kidney help convert vitamin D to its active hormone form. The major biologic function of Vitamin D is maintaining normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. It promotes bone mineralization in conjunction with a number of other vitamins, minerals (especially magnesium), and hormones. While adequate sun exposure is an ideal means to obtain Vitamin D, most of the population cannot obtain sufficient sunlight during fall and winter months to maintain optimal Vitamin D levels. Vitamin D3 Plus offers a solution for keeping Vitamin D at optimal levels for health.

When there is insufficient Vitamin D in the body, bones can become thin, brittle, soft, or misshapen. Vitamin D prevents rickets (in children) and osteomalacia (softening of bones) (in adults). These skeletal diseases result in defects that can severely weaken bones. It is estimated that over 25 million adults in the United States either have developed osteoporosis or are at risk of developing it. Osteoporosis is a disease characterized by fragile bones. It results in increased risk of bone fractures. Vitamin D deficiency was recognized as the cause of rickets and osteomalacia 75 years ago. The prevention and cure of these diseases with fish liver oil was a triumph for nutritional science and since then the body’s requirement for Vitamin D has been linked to these conditions.

Vitamin D deficiency also has been associated with greater incidence of hip fractures. In older women, a higher Vitamin D intake from diet and supplements is associated with less bone loss. Vitamin D supplementation therefore may help prevent fractures resulting from osteoporosis and the loss of bone. Vitamin D supplements offer a significant means for strengthening bones and skeletal structures, and for preventing bone weakness or bone loss leading to osteomalacia, osteoporosis, and other conditions related to weak bones.

VITAMIN D SERVES MANY FUNCTIONS

Vitamin D affects major aspects of human health beyond its classical role in mineral metabolism. It is well established that the active form of Vitamin D acts an effective regulator of cell growth and differentiation in a number of different cell types. Laboratory, animal, and epidemiologic evidence strongly suggest that Vitamin D may be protective against some tumorigenesis. The active form of Vitamin D therefore plays a critical role in supporting good health.

Vitamin D deficiency has been associated with insulin deficiency and insulin resistance. It was shown recently that Vitamin D deficiency is likely a major factor for the development of type 1 diabetes in children. Insulin resistance is also one of the major factors leading not only to tumor formation, but also to heart disease—by far the leading cause of death in the USA. Northern countries have higher levels of heart disease and more heart attacks occur in the winter months.

Degenerative arthritis of the knee and hip progresses more rapidly in people who have lower concentrations of Vitamin D. Infertility is associated with low levels of Vitamin D, and PMS has been completely reversed by the addition of calcium, magnesium, and Vitamin D. Activated Vitamin D in the adrenal gland regulates tyrosine hydroxylase, the rate limiting enzyme necessary for the production of dopamine, epinephrine, and norepinephrine. Low Vitamin D levels also may contribute to chronic fatigue and depression. Seasonal Affective Disorder (SAD) has been treated successfully with Vitamin D.

Multiple Sclerosis, Sjogren’s Syndrome, rheumatoid arthritis, thyroiditis and Crohn’s disease have all been linked with low Vitamin D levels. It has been shown that long term low-level exposure to sunlight normalizes immune function and enhances immune cell production. This reduces abnormal inflammatory responses, such as those found in autoimmune disorders, and reduces occurrences of infectious disease.

Vitamin D deficiency also has been linked with obesity. Vitamin D recently has been shown to lower leptin secretion. Leptin is a hormone produced by fat cells and is involved in weight regulation. Obesity itself lessens the bioavailability of Vitamin D from skin and dietary sources because it is deposited in body fat. Vitamin D deficiency, moreover, has been clearly linked with Syndrome X (also known as Metabolic Syndrome). Syndrome X refers to a cluster of health conditions that includes insulin resistance (the inability to effectively process dietary carbohydrates and sugars), abnormal blood fats (e.g., elevated cholesterol and triglycerides), high blood pressure, and obesity.

VITAMIN A BENEFITS

Vitamin A is useful for many health conditions, including vision problems, poor thyroid function, and weakened immunity. Vitamin A is highly effective against infections (especially those that involve the mucous membranes) largely because it is critical to the formation of tissues lining the digestive, respiratory, reproductive, and urinary tracts. It is also required for the digestion of protein, and for lactation, reproduction, healthy skin and eyes, and the formation of steroid hormones. Vitamin A deficiency can result in a number of health problems, including night blindness, dry eyes, eye infections, and skin conditions. Vitamin A works together with Vitamin D and Vitamin K2 to maintain healthy bones. Vitamin D has been shown to prevent Vitamin A toxicity. Vitamin D3 Plus includes Vitamin A because Vitamin A and Vitamin D work together to support health.

VITAMIN K2 BENEFITS

Vitamin K2 in the form of MK-7 has been shown in numerous studies to extract calcium from the blood and arteries and deposit calcium into growing or aging bones. In addition, MK-7 appears to have the potential to prevent or even reverse some forms of heart disease and, at the same time, do the same for bone loss. It is believed that patients would be able to be treated with doses of vitamin D that possess greater therapeutic value than those currently being used while avoiding the risk of adverse effects by administering Vitamin D together with Vitamins A and K2. Vitamin D3 Plus includes Vitamin K2 (as MK-7) because MK-7 provides unique benefits for health that complement the benefits offered by Vitamin D. They act synergistically to provide other benefits beyond the benefits each by itself can provide.

VITAMIN D3 PLUS INFORMATION

COMPOSITION: One softgel capsule of VITAMIN D3 PLUS provides the following percentages of the US Daily Value for adults:

vitamin d3 plus table

RECOMMENDATIONS: Recent research on Vitamin D suggests that most people will benefit from 125 mcg (5,000 IU) of Vitamin D3 daily (unless there is some constraining lifestyle factor or medical reason). Due to its long half-life (about 30 days) in the body, Vitamin D can be taken effectively in smaller doses if needed (e.g., 5,000 IU taken fewer times per week). For example, taking one capsule once per week would give a daily equivalent dose of about 714 IU (i.e., 5,000 IU divided by seven days).

Additional important nutrients you need to take with Vitamin D3 in order to achieve maximum benefits include magnesium, calcium, zinc, and boron. These additional nutrients are included in our foundational supplements (multivitamins, essential fats, Vitamin C formulas, and Rejuvenate!™ superfoods) and bone formulas (Bone Jour!™ and Bone Guardian).

DIRECTIONS: As a dietary supplement take one capsule of Vitamin D3 Plus daily with food, or as directed by a health care professional. Note: when exposure to direct sunlight is adequate, your requirements for supplemental Vitamin D may be correspondingly lower.

INGREDIENTS: Fish liver oil (providing Vitamin D3), bovine source gelatin (shell), glycerin (shell), yellow beeswax (shell), purified water (shell), rice bran oil, non-GMO sunflower lecithin, Oryza oil, turmeric powder (shell), Vitamin K2 (menaquinone-7), and fish liver oil (providing Vitamin A).

VITAMIN D3 PLUS does not contain wheat, rye, oats, corn, barley, soy, gluten, sugar, wax, egg, yeast, dairy, GMOs, sulfates, chlorides, coloring agents, or artificial preservatives.

VITAMIN B12: THE NEGLECTED NUTRIENT

Dr. Hank Liers, PhD vitamin B12 B-12 cobalamin methylcobalaminI previously wrote METHYLATION CYCLE, GENETICS, B VITAMINS in which I considered in-depth how the Methylation Cycle functions, how genetics affect metabolic pathways, and how B vitamins (including vitamin B12, folate, vitamin B6, and vitamin B2) are used in Methylation Cycle pathways. In today’s article, I take an in-depth view of what you need to know about vitamin B12, including the effects of not having sufficient amounts of Vitamin B12 in the body.

Vitamin B12 is one of eight B vitamins. It is the largest and most structurally complicated vitamin. It consists of a class of chemically related compounds (vitamers), all of which show physiological activity. It contains the biochemically rare element cobalt positioned in the center of a chemical ring structure.

Vitamin B12 (also called cobalamin) is a water-soluble vitamin that is involved in the metabolism of every cell of the human body. It is a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is particularly important in the normal functioning of the nervous system via its role in the synthesis of myelin and in the maturation of developing red blood cells in the bone marrow.

YOUR NEED FOR VITAMIN B12

Vitamin B12 deficiency is thought to be one of the leading nutritional deficiencies in the world. An extensive 2004 study showed that deficiency is a major health concern in many parts of the world, including the North America, Central and South America, India, and certain areas in Africa. It is estimated that 40 percent of people may have low levels of vitamin B12.

Vitamin B12 affects your mood, energy level, memory, nervous system, heart, skin, hair, digestion and more. It is a key nutrient regarding adrenal fatigue and multiple metabolic functions including enzyme production, DNA synthesis, and hormonal balance.

Because of vitamin B12’s extensive roles within the body, a vitamin deficiency can show up in many different symptoms, such as chronic fatigue, mood disorders such as depression, chronic stress, and low energy.

SOURCES OF VITAMIN B12

The only organisms to produce vitamin B12 are certain bacteria and archaea. Some of these bacteria are found in the soil around the grasses that ruminants eat. They are taken into the animal, proliferate, form part of their gut flora, and continue to produce vitamin B12.

Products of animal origin such as beef (especially liver), chicken, pork, eggs, dairy, clams, and fish constitute the primary food source of vitamin B12. Older individuals and vegans are advised to use vitamin B12 fortified foods and supplements to meet their needs.

Salmon is a good source of Vitamin B12

Commercially, Vitamin B12 is prepared by bacterial fermentation. Fermentation by a variety of microorganisms yields a mixture of methylcobalamin, hydroxocobalamin, and adenosylcobalamin. Since multiple species of propionibacterium produce no exotoxins or endotoxins and have been granted GRAS status (generally regarded as safe) by the United States Food and Drug Administration, they are the preferred bacterial fermentation organisms for vitamin B12 production.

Methylcobalamin and 5-deoxyadenosylcobalamin are the forms of vitamin B12 used in the human body (called coenzyme forms). The form of cobalamin used in many some nutritional supplements and fortified foods, cyanocobalamin, is readily converted to 5-deoxyadenosylcobalamin and methylcobalamin in the body.

Hydroxocobalamin is the direct precursor of methylcobalamin and 5-deoxyadenosylcobalamin. In mammals, cobalamin is a cofactor for only two enzymes, methionine synthase (MS) and L-methylmalonyl-coenzyme A mutase (MUT).

Unlike most other vitamins, B12 is stored in substantial amounts, mainly in the liver, until it is needed by the body. If a person stops consuming the vitamin, the body’s stores of this vitamin usually take about 3 to 5 years to exhaust. Vitamin B12 is primarily stored in the liver as 5-deoxyadenosylcobalamin, but is easily converted to methylcobalamin.

ABSORPTION OF VITAMIN B12

Vitamin B12, bound to protein in food, is released by the activity of hydrochloric acid and gastric protease in the stomach. Intestinal absorption of vitamin B12 requires successively three different protein molecules: Haptocorrin, Intrinsic Factor and Transcobalamin II. If there are deficiencies in any of these factors absorption of Vitamin B12 can be seriously decreased.

When vitamin B12 is added to fortified foods and dietary supplements, it is already in free form and, thus, does not require the separation from food protein step. Free vitamin B12 then combines with intrinsic factor, a glycoprotein secreted by the stomach’s parietal cells, and the resulting complex undergoes absorption within the distal ileum by receptor-mediated endocytosis.

Approximately 56% of a 1 mcg oral dose of vitamin B12 is absorbed, but absorption decreases drastically when the capacity of intrinsic factor is exceeded (at 1–2 mcg of vitamin B12).

VITAMIN B12 DEFICIENCY

Vitamin B12 deficiency can be difficult to detect, especially since the symptoms of a vitamin B12 deficiency can be similar to many common symptoms, such as feeling tired or unfocused, experienced by people for a variety of reasons.

Vitamin B12 deficiency is commonly associated with chronic stomach inflammation, which may contribute to an autoimmune vitamin B12 malabsorption syndrome called pernicious anemia and to a food-bound vitamin B12 malabsorption syndrome. Poor absorption of vitamin may be related to coeliac disease. Impairment of vitamin B12 absorption can cause megaloblastic anemia and neurologic disorders in deficient subjects. In some cases, permanent damage can be caused to the body when B12 amounts are deficient.

It is noteworthy that normal function of the digestive system required for food-bound vitamin B12 absorption is commonly impaired in individuals over 60 years of age, placing them at risk for vitamin B12 deficiency.

A diagnosis of vitamin B12 deficiency is typically based on the measurement of serum vitamin B12 levels within the blood. However, studies show that about 50 percent of patients with diseases related to vitamin B12 deficiency have normal B12 levels when tested. This can cause individuals to ignore taking in adequate levels of vitamin B12 with potential serious consequences.

FUNCTIONS AND ISSUES ASSOCIATED WITH VITAMIN B12 STATUS IN THE BODY

  • Vitamin B12 or cobalamin plays essential roles in folate metabolism and in the synthesis of the citric acid cycle intermediate, succinyl-CoA.
  • Vitamin B12 deficiency is commonly associated with chronic stomach inflammation, which may contribute to an autoimmune vitamin B12 malabsorption syndrome called pernicious anemia and to a food-bound vitamin B12 malabsorption syndrome. Impairment of vitamin B12 absorption can cause megaloblastic anemia and neurologic disorders in deficient subjects.
  • Normal function of the digestive system required for food-bound vitamin B12 absorption is commonly impaired in individuals over 60 years of age, placing them at risk for vitamin B12 deficiency.
  • Vitamin B12 and folate are important for homocysteine metabolism. Elevated homocysteine levels in blood are a risk factor for cardiovascular disease (CVD). B vitamin supplementation has been proven effective to control homocysteine levels.
  • The preservation of DNA integrity is dependent on folate and vitamin B12 availability. Poor vitamin B12 status has been linked to increased risk of breast cancer in some, but not all, observational studies.
  • Low maternal vitamin B12 status has been associated with an increased risk of neural tube defects (NTD), but it is not known whether vitamin B12 supplementation could help reduce the risk of NTD.
  • Vitamin B12 is essential for the preservation of the myelin sheath around neurons and for the synthesis of neurotransmitters. A severe vitamin B12 deficiency may damage nerves, causing tingling or loss of sensation in the hands and feet, muscle weakness, loss of reflexes, difficulty walking, confusion, and dementia.
  • While hyperhomocysteinemia may increase the risk of cognitive impairment, it is not clear whether vitamin B12 deficiency contributes to the risk of dementia in the elderly. Although B-vitamin supplementation lowers homocysteine levels in older subjects, the long-term benefit is not yet known.
  • Both depression and osteoporosis have been linked to diminished vitamin B12 status and high homocysteine levels.
  • The long-term use of certain medications, such as inhibitors of stomach acid secretion, can adversely affect vitamin B12 absorption.
  • Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis.

MORE DETAILS ASSOCIATED WITH VITAMIN B12 STATUS IN THE BODY

1. Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis. Vitamin B12 as methylcobalamin functions as a cofactor for methionine synthase. Methionine synthase (MS) catalyzes the conversion of homocysteine to methionine. Methionine along with ATP is required for the formation of S-adenosylmethionine (SAMe), a universal methyl donor for almost 100 different substrates, including DNA, RNA, hormones, proteins, and lipids.
2. Vitamin B12 as 5-deoxyadenosylcobalamin functions as a cofactor along with L-methylmalonyl-CoA mutase (MUT) to convert L-methylmalonyl-CoA to succinyl-CoA in the degradation of propionate, an essential biochemical reaction in fat and protein metabolism. Succinyl-CoA is also required for hemoglobin synthesis.
Metabolic Pathway

 

3. Vitamin B12, bound to protein in food, is released by the activity of hydrochloric acid and gastric protease in the stomach. When synthetic vitamin B12 is added to fortified foods and dietary supplements, it is already in free form and, thus, does not require this separation step. Free vitamin B12 then combines with intrinsic factor, a glycoprotein secreted by the stomach’s parietal cells, and the resulting complex undergoes absorption within the distal ileum by receptor-mediated endocytosis. Approximately 56% of a 1 mcg oral dose of vitamin B12 is absorbed, but absorption decreases drastically when the capacity of intrinsic factor is exceeded (at 1–2 mcg of vitamin B12).

4. Pernicious anemia is an autoimmune disease that affects the gastric mucosa and results in gastric atrophy. This leads to the destruction of parietal cells, achlorhydria, and failure to produce intrinsic factor, resulting in vitamin B12 malabsorption. If pernicious anemia is left untreated, it causes vitamin B12 deficiency, leading to megaloblastic anemia and neurological disorders, even in the presence of adequate dietary intake of vitamin B12.

5. Vitamin B12 status is typically assessed via serum or plasma vitamin B12 levels. Values below approximately 170–250 pg/mL (120–180 picomol/L) for adults indicate a vitamin B12 deficiency. However, evidence suggests that serum vitamin B12 concentrations might not accurately reflect intracellular concentrations. An elevated serum homocysteine level (values >13 micromol/L) might also suggest a vitamin B12 deficiency. However, this indicator has poor specificity because it is influenced by other factors, such as low vitamin B6 or folate levels. Elevated methylmalonic acid levels (values >0.4 micromol/L) might be a more reliable indicator of vitamin B12 status because they indicate a metabolic change that is highly specific to vitamin B12 deficiency.

6. Vitamin B12 deficiency is characterized by megaloblastic anemia, fatigue, weakness, constipation, loss of appetite, and weight loss. Neurological changes, such as numbness and tingling in the hands and feet, can also occur . Additional symptoms of vitamin B12 deficiency include difficulty maintaining balance, depression, confusion, dementia, poor memory, and soreness of the mouth or tongue. The neurological symptoms of vitamin B12 deficiency can occur without anemia, so early diagnosis and intervention is important to avoid irreversible damage. During infancy, signs of a vitamin B12 deficiency include failure to thrive, movement disorders, developmental delays, and megaloblastic anemia. Many of these symptoms are general and can result from a variety of medical conditions other than vitamin B12 deficiency.

7. Typically, vitamin B12 deficiency is treated with vitamin B12 injections, since this method bypasses potential barriers to absorption. However, high doses of oral vitamin B12 can also be effective. The authors of a review of randomized controlled trials comparing oral with intramuscular vitamin B12 concluded that 2,000 mcg (I like 5,000 mcg) of oral vitamin B12 daily, followed by a decreased daily dose of 1,000 mcg and then 1,000 mcg weekly and finally, monthly might be as effective as intramuscular administration. Overall, an individual patient’s ability to absorb vitamin B12 is the most important factor in determining whether vitamin B12 should be administered orally or via injection. In most countries, the practice of using intramuscular vitamin B12 to treat vitamin B12 deficiency has remained unchanged.

8. Large amounts of folate can mask the damaging effects of vitamin B12 deficiency by correcting the megaloblastic anemia caused by vitamin B12 deficiency without correcting the neurological damage that also occurs. Moreover, preliminary evidence suggests that high serum folate levels might not only mask vitamin B12 deficiency, but could also exacerbate the anemia and worsen the cognitive symptoms associated with vitamin B12 deficiency. Permanent nerve damage can occur if vitamin B12 deficiency is not treated. For these reasons, folate intake from fortified food and supplements should not exceed 1,000 mcg daily in healthy adults.

Groups at Risk of Vitamin B12 Deficiency

The main causes of vitamin B12 deficiency include vitamin B12 malabsorption from food, pernicious anemia, postsurgical malabsorption, and dietary deficiency. However, in many cases, the cause of vitamin B12 deficiency is unknown. The following groups are among those most likely to be vitamin B12 deficient.

Older adults: Atrophic gastritis, a condition affecting 10%–30% of older adults, decreases secretion of hydrochloric acid in the stomach, resulting in decreased absorption of vitamin B12. Decreased hydrochloric acid levels might also increase the growth of normal intestinal bacteria that use vitamin B12, further reducing the amount of vitamin B12 available to the bodY.

Individuals with atrophic gastritis are unable to absorb the vitamin B12 that is naturally present in food. Most, however, can absorb the synthetic vitamin B12 added to fortified foods and dietary supplements. As a result, the IOM recommends that adults older than 50 years obtain most of their vitamin B12 from vitamin supplements or fortified foods. However, some elderly patients with atrophic gastritis require doses much higher than the RDA to avoid subclinical deficiency.

Individuals with pernicious anemia: Pernicious anemia, a condition that affects 1%–2% of older adults, is characterized by a lack of intrinsic factor. Individuals with pernicious anemia cannot properly absorb vitamin B12 in the gastrointestinal tract. Pernicious anemia is usually treated with intramuscular vitamin B12. However, approximately 1% of oral vitamin B12 can be absorbed passively in the absence of intrinsic factor, suggesting that high oral doses of vitamin B12 might also be an effective treatment.

Individuals with gastrointestinal disorders: Individuals with stomach and small intestine disorders, such as celiac disease and Crohn’s disease, may be unable to absorb enough vitamin B12 from food to maintain healthy body stores. Subtly reduced cognitive function resulting from early vitamin B12 deficiency might be the only initial symptom of these intestinal disorders, followed by megaloblastic anemia and dementia.

Individuals who have had gastrointestinal surgery: Surgical procedures in the gastrointestinal tract, such as weight loss surgery or surgery to remove all or part of the stomach, often result in a loss of cells that secrete hydrochloric acid and intrinsic factor. This reduces the amount of vitamin B12, particularly food-bound vitamin B12, that the body releases and absorbs. Surgical removal of the distal ileum also can result in the inability to absorb vitamin B12. Individuals undergoing these surgical procedures should be monitored preoperatively and postoperatively for several nutrient deficiencies, including vitamin B12 deficiency.

Vegetarians: Strict vegetarians and vegans are at greater risk than lacto-ovo vegetarians and non-vegetarians of developing vitamin B12 deficiency because natural food sources of vitamin B12 are limited to animal foods. Fortified breakfast cereals and fortified nutritional yeasts are some of the only sources of vitamin B12 from plants and can be used as dietary sources of vitamin B12 for strict vegetarians and vegans. Fortified foods vary in formulation, so it is important to read the Nutrition Facts labels on food products to determine the types and amounts of added nutrients they contain.

Pregnant and lactating women who follow strict vegetarian diets and their infants: Vitamin B12 crosses the placenta during pregnancy and is present in breast milk. Exclusively breastfed infants of women who consume no animal products may have very limited reserves of vitamin B12 and can develop vitamin B12 deficiency within months of birth. Undetected and untreated vitamin B12 deficiency in infants can result in severe and permanent neurological damage.

The American Dietetic Association recommends supplemental vitamin B12 for vegans and lacto-ovo vegetarians during both pregnancy and lactation to ensure that enough vitamin B12 is transferred to the fetus and infant. Pregnant and lactating women who follow strict vegetarian or vegan diets should consult with a pediatrician regarding vitamin B12 supplements for their infants and children.

Health Risks from Excessive Vitamin B12

The IOM did not establish a UL for vitamin B12 because of its low potential for toxicity. In Dietary Reference Intakes: Thiamin, Riboflavin, Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid, Biotin, and Choline, the IOM states that “no adverse effects have been associated with excess vitamin B12 intake from food and supplements in healthy individuals”.

Findings from intervention trials support these conclusions. In the NORVIT and HOPE 2 trials, vitamin B12 supplementation (in combination with folic acid and vitamin B6) did not cause any serious adverse events when administered at doses of 0.4 mg for 40 months (NORVIT trial) and 1.0 mg for 5 years (HOPE 2 trial).

Interactions with Medications

Vitamin B12 has the potential to interact with certain medications. In addition, several types of medications might adversely affect vitamin B12 levels. A few examples are provided below. Individuals taking these and other medications on a regular basis should discuss their vitamin B12 status with their healthcare providers.

Chloramphenicol: Chloramphenicol (Chloromycetin®) is a bacteriostatic antibiotic. Limited evidence from case reports indicates that chloramphenicol can interfere with the red blood cell response to supplemental vitamin B12 in some patients.

Proton pump inhibitors: Proton pump inhibitors, such as omeprazole (Prilosec®) and lansoprazole (Prevacid®), are used to treat gastroesophageal reflux disease and peptic ulcer disease. These drugs can interfere with vitamin B12 absorption from food by slowing the release of gastric acid into the stomach. However, the evidence is conflicting on whether proton pump inhibitor use affects vitamin B12 status. As a precaution, healthcare providers should monitor vitamin B12 status in patients taking proton pump inhibitors for prolonged periods.

H2 receptor antagonists: Histamine H2 receptor antagonists, used to treat peptic ulcer disease, include cimetidine (Tagamet®), famotidine (Pepcid®), and ranitidine (Zantac®). These medications can interfere with the absorption of vitamin B12 from food by slowing the release of hydrochloric acid into the stomach. Although H2 receptor antagonists have the potential to cause vitamin B12 deficiency, no evidence indicates that they promote vitamin B12 deficiency, even after long-term use. Clinically significant effects may be more likely in patients with inadequate vitamin B12 stores, especially those using H2 receptor antagonists continuously for more than 2 years.

Metformin: Metformin, a hypoglycemic agent used to treat diabetes, might reduce the absorption of vitamin B12, possibly through alterations in intestinal mobility, increased bacterial overgrowth, or alterations in the calcium-dependent uptake by ileal cells of the vitamin B12-intrinsic factor complex. Small studies and case reports suggest that 10%–30% of patients who take metformin have reduced vitamin B12 absorption. In a randomized, placebo controlled trial in patients with type 2 diabetes, metformin treatment for 4.3 years significantly decreased vitamin B12 levels by 19% and raised the risk of vitamin B12 deficiency by 7.2% compared with placebo. Some studies suggest that supplemental calcium might help improve the vitamin B12 malabsorption caused by metformin, but not all researchers agree.

ABSTRACT

Background: Low vitamin B-12 status is prevalent among the elderly, but few studies have examined the association between vitamin B-12 status and intake.
Objective: We hypothesized that vitamin B-12 concentrations vary according to intake source.
Design: Plasma concentrations and dietary intakes were assessed cross-sectionally for 2999 subjects in the Framingham Offspring Study. The prevalence of vitamin B-12 concentrations <148, 185, and 258 pmol/L was examined by age group (26–49, 50–64, and 65–83 y), supplement use, and the following food intake sources: fortified breakfast cereal, dairy products, and meat.
Results: Thirty-nine percent of subjects had plasma vitamin B-12 concentrations <258 pmol/L, 17% had concentrations <185 pmol/L, and 9% had concentrations <148 pmol/L, with little difference between age groups. Supplement users were significantly less likely than non-supplement-users to have concentrations <185 pmol/L (8% compared with 20%, respectively). Among non-supplement-users, there were significant differences between those who consumed fortified cereal >4 times/wk (12%) and those who consumed no fortified cereal (23%) and between those in the highest and those in the lowest tertile of dairy intake (13% compared with 24%, respectively), but no significant differences by meat tertile. Regression of plasma vitamin B-12 on log of intake, by source, yielded significant slopes for each contributor adjusted for the others. For the total group, b = 40.6 for vitamin B-12 from vitamin supplements. Among non-supplement-users, b = 56.4 for dairy products, 35.2 for cereal, and 16.7 for meat. Only the meat slope differed significantly from the others.
Conclusions: In contrast with previous reports, plasma vitamin B-12 concentrations were associated with vitamin B-12 intake. Use of supplements, fortified cereal, and milk appears to protect against lower concentrations. Further research is needed to investigate possible differences in bioavailability.

D-RIBOSE: ENERGIZING SMART SUGAR

Fred Liers PhD riboseAvoiding excess dietary sugars is one of the healthiest things. But there is one sugar that really is good for you. That sugar is D-ribose.

In fact, D-ribose is so healthy for you, it may be the one sugar you won’t want to live without. A little background to this amazing sugar.

D-ribose is a 5-carbon monosaccharide occurring naturally in living cells. D-ribose importantly forms the carbohydrate parts of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). That means d-ribose is the sugar essential for the biological function of all living creatures, including humans.

Supplemental D-ribose is associated with many benefits. These benefits include greater energy, less fatigue, and faster muscle recovery. These benefits relate to the capacities of D-ribose as a total body energizer because it boosts energy production (as ATP) in the body.

For individuals suffering low energy levels associated with chronic fatigue syndrome (CFS), low energy levels, and other problems related to low energy (ATP) production, D-ribose can mean a significantly higher level of energy. In cases of extremely low energy, it can mean the capacity to function more normally.

D-ribose energizes every cell in our bodies.

Athletes and bodybuilders were among the earliest to recognize D-ribose for purposes of improving performance and recovery times. D-Ribose also exerts anti-anxiety, stress reduction, and potential anti-depressant properties. There is additional evidence suggesting that supraphysiological amounts of ribose may have cardioprotective effects, especially for the ischemic heart.

Supplemental D-ribose usually comes in the form of a sweet, crystalline, water-soluble powder. It is also available in capsules or tablets, including chewable tablets.

Humans synthesize d-ribose from foods, including glucose and various dietary sugars. But there are benefits to supplemental D-ribose. One of the major reasons is the important role of D-ribose in the production of energy (ATP) in human cells.

• FASTER RECOVERY

• REDUCED FATIGUE

• IMPROVES ATHLETIC PERFORMANCE

• SUPPORTS LONGEVITY OF BLOOD CELLS

• ANTI-ANXIETY EFFECTS

• STRESS REDUCTION

RIBOSE FOR ENERGY (ATP) PRODUCTION

The body uses D-ribose to generate adenosine triphosphate (ATP).  ATP provides energy for all bodily movements and every chemical reaction in cells. ATP is the source of all energy in the body and it’s constantly broken down and recreated due to the processes of life.

The adenine portion of ATP consists of one molecule of adenine and ribose (i.e., five-carbon sugar). The triphosphate portion of ATP consists of three phosphate molecules. When a phosphate breaks off from ATP, then energy is released. The compound then becomes adenosine diphosphate (ADP), which consists of adenosine and two phosphate molecules. When another phosphate molecule breaks off, it becomes adenosine monophosphate (AMP).

It is well established that ratios of ATP, ADP, and AMP are essential for regulating energy in cells. Under extreme physiological stress (e.g., high-intensity exercise), our cells cannot recreate ATP rapidly enough to supply cells with required energy. Concentrations of ADP and AMP rise causing a reduction in cellular energy. When the body’s rate of ATP use continues exceeding the rate at which it can be generated, cells “lose” nucleotides in order to restore the ratio between ATP, ADP, and AMP.

During anaerobic metabolism, AMP levels can rise within cells, thereby disturbing the ratios of ATP to ADP and AMP. The body can reduce AMP concentrations by degrading AMP to simpler end products resulting in a significant decrease in the adenine nucleotide pool. Under extreme conditions (e.g., prolonged high-intensity exercise or the diminished blood flow to tissues witnessed in ischemia), the adenine nucleotide pool may decrease by 30–50%. These effects can significantly compromise physical performance.

Here is where D-ribose supplementation works to support energy production. Supplemental D-ribose allows the body to bypass relatively slow conversion steps required for recreating the adenosine nucleotide providing critical material for ATP production. That is, D-ribose can increase the speed of nucleotide replacement. This has implications not only for sports performance, but also for general health. D-ribose is especially useful in situations where greater energy may be required, as in low energy, chronic fatigue, fibromyalgia, or combating the effects of aging.

D-RIBOSE RATE-LIMITING SUGAR FOR NUCLEOTIDE SYNTHESIS

One of the most important aspects of D-ribose for health relates to the fact that it is the rate-limiting compound that regulates the activity of the purine nucleotide pathway of adenine nucleotide metabolism. As such, ribose plays a central role not only in the synthesis of ATP, but also of coenzyme-A, flavin adenine dinucleotide (FAD), nicotinamide adenine dinucleotide (NAD), DNA, RNA, and other important cellular constituents.

In fact, D-ribose is the only known compound the body can use for performing this critical metabolic function. Specifically, ribose administration bypasses the slow and rate-limited pentose phosphate pathway to stimulate adenine nucleotide synthesis and salvage in vivo. In addition, it has been shown that de novo adenine nucleotide synthesis in skeletal muscle is rate limited by the availability of ribose.

Specifically, human muscle cells (e.g., heart and skeletal muscle cells) do not rapidly replace lost nucleotides because of the lack of two rate-limiting enzymes in the pentose phosphate pathway metabolizing glucose to ribose-5-phosphate. Ribose itself forms 5-phosphoribosyl-1-pyrophosphate, a rate-limiting compound in nucleotide synthesis. As noted, supplemental D-ribose allow the body to bypass the rate-limited steps of the pentose phosphate pathway, thereby accelerating nucleotide synthesis (and salvage).

STOPPING THE VICIOUS CYCLE OF ENERGY DEPLETION

It should not take a genius to figure out that when energy production is optimized, overall health will improve. Yet, the same principle also applies in reverse. That is, there are many instances in which low energy levels can fuel lower energy levels. For example, when illness, stressors, or other factors deplete large amounts of the body’s supply of energy, they can gradually (or not so gradually) lessen the body’s capacity to produce more by overtaxing the energy production system.

This cascade of reduced energy production can become a vicious cycle in which there are few reserves left to support the body’s need for greater energy. D-Ribose is one of the only nutrients that can reverse the downward spiral in ATP production when demands exceed supply. By feeding the body’s own system for producing energy, and thereby supplying the raw material required to produce it, supplemental D-ribose can helps break the cycle of low energy levels.

Chronic low energy? D-ribose is required for creating energy for all biological functions.

A ROLE FOR SUPPLEMENTAL D-RIBOSE

To recap the importance of supplemental D-ribose: D-ribose increases the rate at which ATP is generated. This improves exercise performance and allows for faster muscle growth. All this is possible because supplemental ribose helps the body bypass the conversion steps needed to create or re-create adenosine nucleotides.

Because replacing adenine nucleotides normally requires a certain amount of time, providing the body with D-ribose supplementally via diet can reduce rates of healing and repair in muscle cells. That is, supplemental D-ribose can increase the speed at which adenosine nucleotides are replaced by providing raw material for the creation of more ATP. That is how D-ribose improves athletic performance and supports optimal energy production, as well as optimal muscle health.

The significance of the science behind ATP production is that almost everyone can benefit from supplemental D-ribose. Whether you are an athlete requiring rapid repletion of energy, a person suffering from low energy levels or chronic fatigue, or anyone who wishes to improve energy production supporting optimal health.

REJUVENATE! SUPERFOODS INCLUDE D-RIBOSE

We at HPDI have focused our efforts on formulating the most effective nutritional supplements and superfoods. When Dr. Hank Liers formulated our original high-RNA Rejuvenate! superfood, he put D-ribose into it. In fact, all of our Rejuvenate! superfoods provide significant amounts of D-ribose.

Rejuvenate! (original greens) provides 1,500 mg D-ribose per serving (one small scoop). Rejuvenate! PLUS provides 1,800 mg per serving (two scoops). Rejuvenate! Berries & Herbs provides 2,000 mg per serving (two scoops).

ribose energy dietary nucleic acids rejuvenate superfoods

All Rejuvenate! superfoods provide high levels of D-Ribose.

A major reason HPDI includes D-ribose in its superfoods–and perhaps the most obvious one–is simply that we formulate unique, high-RNA superfoods to support optimal energy production in the body. D-ribose supports that goal by various means.

D-ribose is the rate-limiting sugar for the uptake and assimilation of dietary nucleic acids (RNA, DNA, nucleotides, and nucleosides). This is because D-ribose is actually the sugar backbone of these nutrients. As such, the body requires D-ribose in order to utilize and create (or recreate) dietary nucleic acids.

For example, nucleotides are the molecular building blocks of DNA and RNA. They are chemical compounds consisting of a heterocyclic base, a 5-carbon sugar (ribose or deoxyribose) and at least one phosphate group. They are the monomers of nucleic acids, and 3 or more can bond together to form a nucleic acid.

Nucleosides are glycosylamines consisting of a base (or nucleobase) to a ribose (or deoxyribose) ring. Some nucleosides are cytidine, adenosine, guanosine, and inosine. When nucleosides are phosphorylated in cells, they produce nucleotides (see above).

Thus, D-ribose plays important roles as an essential part of nucleic acids, nucleotides, and nucleosides; in the production of energy (as ATP); and the synthesis and salvage of nucleotides in the body.

Rejuvenate! superfoods are formulated to provide high levels of nucleic acids. D-ribose helps the body optimize its use of nucleic acids and their constituent components. Having D-ribose in our superfoods not only supports energy production directly, but also allows maximum use of the dietary RNA they are formulated to provide.

Rejuvenate! superfoods provide nutrients that boost energy levels significantly and consistently for optimal health, healing, and wellness. The inclusion of D-ribose importantly supports the powerful nucleic acid nutrition these superfoods offer, as well as supplements the body’s intake and synthesis of D-ribose.

REJUVENATE! PLUS provides 1,800 mg of D-ribose per serving.

SUMMARY

D-Ribose of one of the most important natural sugars for life and health. It is one of the few nutrients that can boost energy levels naturally. When taken with other important biological nutrients, including dietary RNA, DNA, nucleotides, and nucleosides, D-ribose is truly a nutritional powerhouse that can support good health and the energy levels required to live life to its fullest. We believe the best way to obtain supplemental D-ribose is to consume Rejuvenate! superfoods.
