VEGAN PRODUCT. Each of Viridian's B complex supplements offers a full range of B vitamins, along with a higher level of B vitamins. High Twelve B12 features higher levels of cyano and methyl cobalamin (Vitamin B12). Vitamin B12 supports the normal functioning of the nervous system, energy-yielding metabolism, normal psychological function, the immune system and the formation of red blood cells. Vitamin B12 contributes to the reduction of tiredness and fatigue. Working with vitamins B6 and folic acid and B12 make a decisive contribution to normal homocysteine metabolism. Most B-complexes found in supermarkets and pharmacies do not contain high levels of the B vitamins. Viridian's High Twelve B Complex includes vitamin B12 at 500mcg (ug), vitamin B6 at 20mg, and folic acid at 200 mcg (ug), along with all the other B vitamins. This combination has been extensively studied. How to use: As a dietary supplement, take one capsule a day during meals, or follow your doctor's recommendations.
