Biotin acts as a coenzyme for carboxylase enzymes that help the body metabolize fats, carbohydrates, and proteins, which may support keratin infrastructure in hair, skin, and nails.

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.
Take 1 capsule one to two times daily or as recommended by your health-care practitioner.
