Vitamins are essential for the normal growth and development of a multicellular organism.
Vitamins are classified as either water-soluble or fat-soluble. In humans there are basically 13 recognized vitamins: 4 fat-soluble (A, D, E, and K) and 9 water-soluble (8 B vitamins and vitamin C). Water-soluble vitamins dissolve easily in water whereas Fat-soluble vitamins are absorbed through the intestinal tract with the help of lipids (fats).
Many people in the United States and other countries take multivitamins and other supplements, though these may not be necessary or helpful, according to research.
