-High concentrations of naturally occurring biotin are found in meats, dairy products, grains, and pulses (e.g. legumes). Because endogenous microbial synthesis is normally adequate, a dietary supply of biotin is not required. However supplementation may be necessary in situations where intestinal microbial synthesis is compromised, such as long term administration of anti-bacterial agents.

 ==What is Vitamin B7 (Biotin)?==
-'''Vitamin B<sub>7</sub>''', also called '''biotin''', is an '''essential water-soluble vitamin'''. Biotin is actively transported across the intestinal mucosa, with minimal passive [[Diffusion - Physiology|diffusion]], and is typically found as free biotin in [[plasma]]. '''Biotin is not stored in the body and is freely filtered by the [[Nephron Microscopic Anatomy#Proximal Tubule|renal tubules]]'''.
