Biotin is a water-soluble B vitamin that is often marketed as vitamin B7, vitamin H or coenzyme R. It promotes the synthesis of fatty acids, branched-chain amino acids (leucine, isoleucine and valine) and blood sugar production in the liver. Supplemental biotin increases hair and nail growth, and promotes blood sugar regulation. It is safe, even in high doses, so people often take mega-doses of the supplement. High blood biotin levels can interfere with blood chemistry tests, particularly thyroid hormone, causing either falsely high or low values. Biotin interference with lab tests could cause misdiagnosis or incorrect treatments. Stop taking biotin if you are scheduled for a medical examination, and tell your physician about your supplements.
