Biotin, also known as vitamin B7, offers a high dose per capsule. A clinical trial on 45 patients with brittle nails showed that 2.5 mg of biotin supplementation over 1.5-7 months led to firmer, stronger nails in 91% of participants, with noticeable improvement after an average of two months.*

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.*
