'''Vitamin B7''', also called '''biotin''', is an '''essential water-soluble vitamin'''. Biotin is actively transported across the intestinal mucosa, with minimal passive diffusion, and is typically found as free biotin in plasma. '''Biotin is not stored in the body and is freely filtered by the renal tubules'''.
