Patient One Biotin supplies 8 mg of Biotin, an essential, water-soluable B-vitamin that has a beneficial effect on a number of structures and functions in the body. It is best known for its role in promoting healthy hair and nails but also plays a role in supporting glucose metabolism by stimulating glucose-induced insulin secretion in pancreatic beta cells and by accelerating glucose metabolism in the liver.
Biotin is found in small amounts in many foods. Deficiency in biotin is difficult to detect because of the lack of assay techniques to determine biotin concentrations in the blood. Signs of deficiency may include thinning of the hair (frequently with loss of hair color), dry, brittle fingernails, and red scaly rash around the eyes, nose, and mouth.
