Biotin Supplementation
for Hair Loss
Biotin (Vitamin B7) supplementation at 2.5–5mg daily for hair and nail strength.
How it works
Biotin is essential for keratin production. Deficiency causes hair loss and brittle nails. Supplementation corrects deficiency and may improve hair strength.
What to watch for
Only clearly effective if biotin deficiency is present — which is rare in people with adequate diet. High doses can interfere with thyroid and other blood tests — tell your doctor you are taking it. Evidence in non-deficient individuals is weak.
