What Does Vitamin B12 Do?

Vitamin B12 helps keep energy metabolism going by supporting how macronutrients turn into energy and helps nervous system function.

It also helps with red blood cell formation and homocysteine metabolism, which tie into cardiovascular health according to EFSA guidance. Dr. Smith from Harvard University found that B12 takes part in energy metabolism and nervous system maintenance.
