Ingredient and preparation
Melatonin is a hormone produced in response to darkness and helps with circadian timing. Supplements are usually synthetic or microorganism-derived.
Sources: National Center for Complementary and Integrative Health
Evidence and limits
NCCIH reports that supplements may help with jet lag and some circadian-related conditions. It also describes limited or low-quality evidence for several sleep questions and does not support treating chronic insomnia as a generic supplement problem.

Safety and a useful record
Short-term use appears safe for many adults, but long-term safety is less clear. Medicine interactions, pregnancy, breastfeeding and age-related concerns need individual advice.
