Methylcobalamin is an active coenzyme form of vitamin B-12 that is more bioavailable than the common form, cyanocobalamin. B-12 is essential for healthy red blood cells, energy level, and DNA production, and plays an important role in maintaining normal nerve function. It is often lacking in a vegan diet because it is normally found in meat, seafood, eggs, and dairy. Vegan True® Methylcobalamin Vitamin B-12 does not contain any animal products or animal-derived ingredients, so it's ideal for vegans.*
