Supports healthy skin, hair and nails*
Biotin offers a high concentration of biotin, a B vitamin that promotes fingernail strength and supports skin, hair, and nerve health, as well as healthy blood sugar metabolism.
Biotin provides a high amount of biotin (also sometimes called vitamin B7) per capsule. Biotin's benefit for fingernail strength was demonstrated in a clinical trial, where 45 patients with brittle nails received oral supplementation of 2.5 mg biotin for 1.5-7 months. Ninety-one percent showed "definite improvement," exhibiting firmer, harder fingernails after an average of two months of supplementation.* Biotin also supports healthy skin, hair, and nerve function.* Biotin in a higher amount, like in Thorne's Biotin, promotes glucose metabolism by stimulating glucose-induced insulin secretion in pancreatic beta cells and by accelerating glucose metabolism in the liver.* Similarly, biotin can enhance muscle insulin sensitivity by increasing the uptake of glucose by muscle cells.
