definition of fat soluble vitamins
Vitamin tablets on a table. Vitamins come in two varieties: water soluble and fat soluble. Water soluble vitamins, such as B complex vitamins and vitamin C, dissolve in water and are excreted through the kidneys if you have excess amounts in your body. Fat-soluble vitamins--namely vitamins A, D, E and K--dissolve in fat and are stored in fat throughout the body.
