Question: what are vitamins essential to good health?
Answer: There are 13 vitamins—vitamins A, C, D, E, K, and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, B6, B12, and folate). Vitamins have different jobs—helping you resist infections, keeping your nerves healthy, and helping your body get energy from food or your blood to clot properly.
