Vitamins are organic compounds that are essential for the normal functioning of the body. They are required in small amounts and cannot be produced by the body, so they need to be obtained through the diet. Vitamins play important roles in various bodily processes such as metabolism, immunity, cell repair, and growth and development. There are 13 essential vitamins, which are divided into two categories: fat-soluble vitamins (vitamins A, D, E, and K) and water-soluble vitamins (vitamins C and the B-complex vitamins). Each vitamin has specific functions and deficiencies can lead to various health problems. Consumption of a balanced diet with a variety of foods is necessary to ensure an adequate intake of vitamins.
