Methylcobalamin, an active coenzyme form of vitamin B-12, is essential for cell growth and replication. It is more concentrated than other forms of B-12 in the cerebral spinal fluid where it can be used by the central nervous system. It donates methyl groups to the myelin sheath that insulates certain nerve fibers. It may also play a role in maintaining a healthy sleep-wake cycle, as well as normal nerve function.

This product contains no yeast, dairy, egg, gluten, soy, wheat, sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

works well I feel full of energy! works great! December 22, 2013
very effective This seems to promote energy. Pills don't dissolve as well as I would like. I have to chew them since they don't dissolve in the three minutes it says it should take. November 25, 2013
Wonderful B-12 Benefits After viewing a video on the different B-12 sources, I went in search of a methylcobalamin B-12 vitamin supplement. I need it because I am deficient in B-12, and take a large dose every day. This product is wonderful! Fast, easy to take, and in a large enough dose to be beneficial to me. I love the large size bottle, too! March 15, 2012
