Vitamins are compounds that occur naturally in foods and are essential for several functions. They can be either fat-soluble or water-soluble. Fat-soluble vitamins are metabolized and stored by the fat in your body. Water-soluble vitamins are not stored and must be consumed every day. Your body excretes the water-soluble vitamins it doesn't use. Eating a balanced diet, incorporating foods from all food groups, ensures you get all of the important vitamins you need.
