Vitamin B12 is necessary for DNA synthesis, neurological function, and red blood cell formation. The active forms of B12 are called methylcobalamin and 5-deoxyadenosylcobalamin. Vitamin B12 is a cofactor for methionine synthase and thereby affects the synthesis of nearly 100 substrates including DNA, RNA, and proteins. The recommended dietary allowance of vitamin B12 is 2.4 mcg for adult U.S. populations. There is no established upper limit for vitamin B12 intake, as it has a low potential for toxicity(1173).
