How It Works
Biotin (B7) is a cofactor for five carboxylase enzymes essential for fatty acid synthesis, gluconeogenesis, and amino acid metabolism. It also regulates gene expression through histone biotinylation. Popular for cosmetic benefits though deficiency is rare.
Dosage & Timing
Recommended Dosage
2,500-10,000 mcg daily for cosmetic benefits
Best Time to Take
Any time, with or without food
Recommended Form
D-Biotin (pure form)
Side Effects
Very safe. IMPORTANT: High doses interfere with laboratory blood tests (troponin, thyroid, etc). Stop 3 days before blood work.
Drug Interactions
CRITICAL: Interferes with biotin-based lab assays. May cause false thyroid and cardiac results. Inform your doctor.
What Does The Research Say?
Deficiency is uncommon. Evidence for hair and nail benefits is limited to deficiency states. Popular supplement but benefits in non-deficient individuals are not well-proven. May help brittle nail syndrome.
