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 doses (5000-8000mcg) 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.
Directions: Take 1 capsule one to two times daily or as recommended by your health professional.
Precautions: If pregnant, consult your health professional before taking Biotin. Biotin supplementation can also interfere with certain lab tests. Consult your health-care professional prior to having your blood drawn.
