Vitamins serve many purposes to help the body stay healthy. Vitamin help the body resist infections, keeps nerves healthy, and helps the body get energy from food. There are 13 vitamins: C, A, D, E, K, and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, B6, B12, and folate).

Others, such as calcium, magnesium, and potassium, are needed in larger amounts. According to the National Institute on Aging, the dosage of vitamins and minerals can depend on age:

Men need 1.7 mg every day. Women need 1.5 mg every day. Vitamin B6 can be obtained from fortified cereals, whole grains, organ meats like liver, and fortified soy-based meat substitutes. Vitamin B6 supplements are also available.
