A member asked:

Prenatal vitamins beneficial for hair growth and nail health?

A doctor has provided 1 answer

No: I don't know how that popular myth got started, but i know of no credible evidence that vitamin tablets do anything for hair or nails. Biotin (available in any health food store) does promote hair and nail growth (5000 units/day) if taken regularly.
