different vitamins helps maintain health:
Release energy. Several B vitamins are key components of certain coenzymes (molecules that aid enzymes) that help release energy from food.
Produce energy. Thiamin, riboflavin, niacin, pantothenic acid, and biotin engage in energy production.
Build proteins and cells. Vitamins B6, B12, and folic acid metabolize amino acids (the building blocks of proteins) and help cells multiply.
Make collagen. One of many roles played by vitamin C is to help make collagen, which knits together wounds, supports blood vessel walls, and forms a base for teeth and bones.
Build bones. Bone formation would be impossible without vitamins A, D, and K.
Protect vision. Vitamin A also helps keep cells healthy and protects your vision.
