Is It Safe to Take Melatonin While Pregnant?

Melatonin is not recommended during pregnancy due to insufficient safety data. The FDA doesn't regulate melatonin as a medication, and most studies on pregnancy safety have been conducted only in animals. Research shows melatonin crosses the placental barrier and may affect fetal development, though human studies are limited. The American College of Obstetricians and Gynecologists advises avoiding melatonin supplements during pregnancy. If you're experiencing sleep issues while pregnant, safer alternatives include maintaining consistent sleep schedules, limiting screen time before bed, and using pregnancy pillows for comfort. Always consult your healthcare provider before taking any supplements during pregnancy.
