Biotin is one of the eight known B-complex vitamins. It is commonly referred to as vitamin B7 or vitamin H and can be found in such foods as liver, yeast, whole grains, soybeans and other meats.

Vitamins are organic substances found in foods and are essential to the body in small quantities for growth, health and preservation of life itself. The body needs vitamins just as it requires other food constituents such as proteins, fats, carbohydrates, minerals and water. The absence of one or more vitamins from the diet, or poor absorption of vitamins, can cause deficiency problems.
