Biotin deficiency during pregnancy may have an adverse impact on biotin supply to the fetus and impair fetal development (10–12).
Biotin is available in tablet or capsule form, and the general recommended dosage for hair health ranges from 2,500 mcg to 10,000 mcg per day. However, it's important to consult with a healthcare provider before starting a supplement regimen to ensure the dosage is right for your specific needs.
