Vitamin B-12. Cherry-Flavored Sublingual. Suitable For Vegans. Methylcobalamin is an active coenzyme form of vitamin B12 that is more bioavailable than the common form, cyanocobalamin. B12 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 B12 does not contain any animal products or animal-derived ingredients, so it’s ideal for vegans.
