Not all B12 is created equal. Thorne supplies vitamin B12 as methylcobalamin — the active, tissue-ready form the body can put straight to work, with no conversion required.

B12 contributes to normal energy metabolism, red blood cell formation, nerve health and methylation. Because it is found mainly in animal foods, this one-a-day capsule is especially useful for vegetarians, vegans and older adults whose absorption of B12 naturally declines.
