Biotin is part of the vitamin B group, although it is not a vitamin. It is a coenzyme, which is acting in combination with vitamins. Biotin gets its name from the Greek word bios, which means "life" and was isolated in 1936 for the first time. It is necessary for the metabolism of fats, carbohydrates and proteins. As a coenzyme it is involved in many processes and it is utilized by every cell in the body. Biotin is involved in energy metabolism and plays a major role in use of glucose. It is essential for cell growth and replication, and enables the formation and maintenance of the chemical structures of keratin (the main protein found in hair and nails). Biotin is a water-soluble; any excess is eliminated via urine.
Biotin is found in various foods, including liver, cauliflower, salmon, carrots, bananas, soy flour, cereals, and yeast. Biotin content of food is reduced by cooking and preserving.
