Vitamin B7 that supports keratin production for hair, skin, and nails.
How it works
Biotin is a cofactor for carboxylase enzymes involved in fatty acid synthesis and amino acid metabolism, which are essential for keratin production.
Evidence-based uses
Most effective for those with biotin deficiency. Can interfere with certain lab tests.
Clinical Evidence
Systematic review found that biotin supplementation may improve hair growth in individuals with biotin deficiency, but evidence is limited for those without deficiency.
Safety
Biotin can interfere with laboratory tests that use biotin-streptavidin technology, including thyroid function tests. Inform your doctor before blood work.
