**Experts weigh in on the benefits and risks of biotin supplements.**
NEW YORK (USA TODAY) – Biotin, a B vitamin also known as vitamin B7, is often touted for its ability to improve hair and nail health. While a biotin deficiency can lead to hair thinning, brittle nails, and other symptoms, experts say that for most people, supplements are unnecessary.
According to several doctors interviewed by USA Today, biotin deficiency is rare. Most individuals obtain sufficient biotin through a balanced diet rich in foods like eggs, nuts, seeds, meat, and fish. Deficiency is more likely in pregnant or breastfeeding women, individuals with chronic alcoholism, or those taking certain medications. In these cases, biotin supplements may be beneficial under medical supervision. However, even then, the decision to supplement should be made in consultation with a doctor to determine the proper dosage, which can range from 8-12 micrograms daily for children to 30 micrograms for adults, and potentially much higher in cases of severe deficiency.
While some studies suggest biotin supplements may improve hair growth in individuals with a pre-existing deficiency and strengthen brittle nails, the evidence supporting their effectiveness in healthy individuals is mixed. For most people, taking biotin supplements is unlikely to significantly impact hair growth or nail strength. Furthermore, excessive biotin intake can interfere with certain medical tests.
Doctors strongly advise against taking biotin supplements without consulting a physician. While generally safe, unnecessary supplementation can mask other underlying health issues and potentially lead to inaccurate test results. A balanced diet remains the most effective way to ensure adequate biotin intake for the vast majority of people.
