Experts Warn Against Daily Biotin Supplements Due to Hidden Health Risks
Biotin supplements are often marketed for improving hair and nail health, but most people get enough from a balanced diet, and supplements mainly benefit those with a deficiency. While biotin supports keratin structure and metabolic functions, evidence for its effectiveness in healthy individuals is limited, and excess intake can interfere with lab tests. It is safest to consult a healthcare provider before taking biotin supplements, especially during pregnancy or if deficiency is suspected.
