Vitamin B-12 is necessary for the production of energy from fats and proteins and is well known for its critical role in DNA synthesis, as well as in homocysteine metabolism.* Methylcobalamin is the co-enzyme form of Vitamin B-12 that has been found to be especially critical in the maintenance of a healthy nervous system.* Dietary sources are almost exclusively of animal origin (meat and dairy) and supplementation with B-12 may be especially important for strict vegetarians. NOW® Methyl B-12 is vegetarian/vegan (non-animal derived).
Most B vitamins function in the body only in their coenzyme (or active) forms, and the regular forms as found in our B-12 or certain B-complex products have to be converted into the coenzyme forms before they can do their job. These coenzyme forms, though, are usually much more expensive and are considered more potent than standard vitamin forms. Methylcobalamin is one of these coenzyme forms. It is derived via microbial fermentation, and since it is water soluble has a large safety margin.
