Vitamins are fat-soluble or water-soluble organic chemicals necessary in small amounts for good health. Humans require 13 different types of vitamins for normal function and must obtain them from plant and animal foods in their diet. Vitamins A, C and E are antioxidants. B vitamins are important in metabolic activity and in making red blood cells.

Vitamins have diverse biochemical functions, including function as hormones (e.g. vitamin D), antioxidants (e.g. vitamin E), and mediators of cell signaling and regulators of cell and tissue growth and differentiation (e.g. vitamin A) [4]. The largest number of vitamins (e.g. B complex vitamins) function as precursors for enzyme cofactor bio-molecules (coenzymes), that help act as catalysts and substrates in metabolism.

Vitamins C and E have been described under antioxidants. Vitamin A is another anti-oxidant vitamin, but since it can be toxic at high doses, it is preferable to take its precursor, beta-carotene (pro-vitamin A), which is water-soluble, and much safer. It is especially beneficial against breast and lung cancer. Other than having potent antioxidant power that fights cancer, all of them have other health benefits.
