It is generally not recommended to take melatonin supplements during pregnancy because there is limited research on its safety and effect on fetal development. Melatonin is a hormone naturally produced by the body, and its levels increase during pregnancy, especially in the third trimester. However, supplements typically contain doses much higher than natural production, and the impact of these high levels on the developing fetus is not well understood. There is some evidence from clinical studies that melatonin use during pregnancy is probably safe, but more research is needed, and its use should only be considered under medical supervision, especially for certain conditions like preeclampsia or if recommended by a healthcare provider. Because melatonin supplements are not regulated by the FDA and can have side effects such as drowsiness, nausea, and headaches, pregnant women are often advised to seek safer alternatives for sleep problems unless directed otherwise by a doctor. In summary, melatonin supplements are usually not recommended during pregnancy due to insufficient safety data, and consulting a healthcare professional before use is essential.
