Vitamins and minerals are nutrients that the body requires to function properly. Vitamins can be fat-soluble or water-soluble. The fat-soluble vitamins are vitamins A, D, E, and K. Fat-soluble vitamins dissolve in fat and are stored in the body.
The B vitamins work collectively and individually in every cell to perform many different jobs, including helping the body release the energy it gets from carbohydrates, proteins and fats. Some foods are especially good sources of just one B vitamin, while other foods contain several B vitamins.
