NOW Foods Methyl B-12 10000 mcg, 60 Lozenges (Pack of 2)

What the brand says

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). Natural color variation may occur in this product.
