Vitamin B12

Vitamin B12 is a water-soluble member of the Vitamin-B Complex, and plays an important role in normal brain and nervous system function and blood formation. Specifically, Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis.[1-5]

Levels only slightly lower than normal may result in a range of symptoms such as fatigue, depression, and poor memory.[6] A Vitamin B12 deficiency may also decrease levels of substances needed to metabolize neurotransmitters.[7]

The two forms of Vitamin B12 that are active in human metabolism are methylcobalamin and 5-deoxyadenosylcobalamin.[5]
