Biotin is an essential B-Vitamin. Without it, certain enzymes do not work properly and various complications can occur involving the skin, intestinal tract, and nervous system.*
Biotin is taken from the Greek word "bios" meaning "life."Although biotin is one of the lesser-known B vitamins, it plays an essential role in a number of important body processes. Taking its name from the Greek word bios, meaning "life," this nutrient assists the body in metabolizing protein, fats, and carbohydrates from food. It plays a special role in enabling the body to use blood sugar (glucose), a major source of energy for body fluids. Biotin also helps produce certain enzymes.
Adults rarely suffer from a deficiency of biotin, in part because it’s found in so many foods, including rice, barley, oatmeal, whole wheat, soy products, and cauliflower. But when low levels do occur, problems such as brittle nails and lackluster hair can develop. Biotin supplements may help in such cases.
