It is essential that vegetarians consume a vitamin B12 supplement to maintain optimal health. Vitamin B12, when ingested, is stored in the liver and other tissues for later use. It supports the maintenance of cells, especially those of the nervous system, bone marrow and intestinal tract. Vitamin B12 is important in homocysteine metabolism (homocysteine is an amino acid that is formed within the body). Normal homocysteine levels are important for maintaining cardiovascular health. Deficiencies of the vitamins folic acid, pyridoxine (B6) or cobalamin (B12) can result in elevated levels of homocysteine. Folate and B12, in their active coenzyme form, are both necessary cofactors for the conversion of homocysteine to methionine, thus helping to maintain healthy blood levels of homocysteine.*Methylcobalamin is one of the naturally-occurring forms of vitamin B12 found in the human body. The liver must convert cyanocobalamin, the form of B12 most commonly used in supplements, into methylcobalamin, before it can be properly utilized by the body; methylcobalamin is more effective than non-active forms of vitamin B12. Methylcobalamin also assists in the formation of SAMe (S-adenosylmethionine), a nutrient that has powerful mood-elevating properties.*Folate [as (6S)-5-methyltetrahydrofolic acid, glucosamine salt, Quatrefolic®] (432 mcg) Folic acid is mainly found in fruits and vegetables. Dark, leafy greens, oranges, orange juice, beans, peas and Brewer’s yeast are the best sources. Folic acid plays a key role by boosting the benefits of B12 supplementation. These two B vitamins join forces and work together in maintaining normal red blood cells. Folic acid assists in the normal utilization of amino acids and proteins, as well as supporting the construction of the material for DNA and RNA synthesis, which is necessary for all bodily functions. Scientific studies have found that when working in tandem with folic acid, B12 is capable of promoting normal homocysteine levels. This works toward supporting a healthy cardiovascular and nervous system.*Folic acid (folate) must go through a series of chemical conversions before it becomes metabolically active to be properly utilized. Folinic acid is thehighly bioavailable, metabolically active derivative of folic acid. It does not require the action of the enzyme dihydrofolinate reductase to become active, so it's not affected by substances and herbs that inhibit this enzyme. inhibition of this enzyme can result in folic acid deficiency. some people have a genetic variation (in the MTHRF gene) that reduces the amount of activated follic acid in the body. Folinic acide, unlike folic acid, is not negatively impacted by this genetic variation.*Quatrefolic® is the glucosamine salt of (6S)-5-methyltetrahydrofolate, the most active form of folate, as it is structurally analogous to the reduced and active form of folic acid. Because this form is naturally present in the body, it is much more bioavailable for its biological action without having to be metabolized in the body. This patented ingredient also provides greater s">Riboflavin-5-Phosphate (Vitamin B2) (3 mg)Vitamin B2 is found in liver, dairy products, dark green vegetables and some types of seafood. Vitamin B2 serves as a coenzyme, working with other B vitamins. It promotes healthy red blood cell formation, supports the nervous system, respiration, antibody production and normal human growth. It supports healthy skin, nails, hair growth and promotes normal thyroid activity (a healthy thyroid is essential in maintaining a healthy weight, among other things). Vitamin B2 supports the body's ability to turn food into energy as a part of the electron transport chain, driving cellular energy on the micro-level. Riboflavin can be useful for pregnant or lactating women, as well as athletes due to their higher caloric needs. Vitamin B2 also promotes the normal breakdown of fats. Vitamin B2 is water-soluble and cannot be stored by the body except in insignificant amounts. It must be replenished daily.*Pyridoxal-5-Phosphate (Vitamin B6) (6 mg)Poultry, fish, whole grains and bananas are the main dietary sources of vitamin B6. B6 is a co-factor required for protein and amino acid metabolism, and helps maintain proper fluid balance. It also assists in the maintenance of healthy red and white blood cells, which keeps our body healthy. Vitamin B6 promotes normal hemoglobin synthesis (hemoglobin is the protein portion of red blood cells which carries oxygen throughout the body). Because vitamin B6 is involved in the synthesis of neurotransmitters in the brain and nerve cells, it has been recommended as a nutrient to support mental function, specifically mood. Athletic supplements often include vitamin B6 because it promotes the conversion of glycogen to glucose for energy in muscle tissue. Vitamin B6, when taken with folic acid, has been shown to help maintain normal plasma levels of homocysteine, which promotes optimal cardiovascular health. Vitamin B6 should be administered as a part of a complex of other B vitamins for best results.*Magnesium (Carbonate) (40 mg)Foods rich in magnesium include unpolished grains, nuts and green vegetables. Green, leafy vegetables are potent sources of magnesium because of their chlorophyll content. Meats, starches, milk, refined and processed foods contain low amounts of magnesium. Recent research sh
