Vitamin B12 works closely with folic acid in many body processes, including DNA synthesis, red blood cell production, serotonin production, nerve health and regulating levels of homocysteine. Vitamin B12 deficiency is not uncommon in the elderly and in vegans. Supplementing folic acid may mask a B12 deficiency.
