A vitamin is an organic compound that is essential for normal growth and functioning in living organisms. These nutrients are required in small amounts and play crucial roles in various bodily processes, such as metabolism, immunity, and cell repair. Vitamins are typically obtained through a balanced diet, as the body cannot produce them in sufficient quantities. There are two main types of vitamins: water-soluble and fat-soluble. Water-soluble vitamins, like vitamin C and the B vitamins, dissolve in water and are not stored in the body, requiring regular intake. Fat-soluble vitamins, such as vitamins A, D, E, and K, are stored in body fat and can be utilized when needed.
