What the research says

Melatonin is a hormone the body makes in the dark; in the US it is sold over the counter as a dietary supplement.^[NCCIH]
NIH says melatonin may help with sleep problems from jet lag or shift work and with how quickly people fall asleep, but two clinical guidelines advised against it for chronic insomnia.^[NCCIH]
A 2013 meta-analysis of randomized trials found melatonin shortened the time to fall asleep by about 7 minutes on average.^[PubMed]
A 2024 dose-response meta-analysis looked at which doses and timing were linked to the largest effects in trials.^[PubMed]

Safety

High doses: trials mostly use 0.5 to 5 mg, while many US products contain more; owners on Reddit link larger doses with next-day grogginess, headaches and vivid dreams.^[PubMed]
Labels are often inaccurate: a 2023 study found 22 of 25 US melatonin gummies were mislabeled, with 74% to 347% of the stated amount; a 2017 study found content varied widely between and within brands.^[PubMed]^[PubMed]^[NCCIH]
Keep it away from children: reports of children swallowing melatonin rose sharply from 2012 to 2021, including hospitalizations.^[PubMed]^[NCCIH]
Short-term use appears safe for most adults, but long-term safety has not been established; ask a doctor before combining it with sedatives or other medicines, or during pregnancy.^[NCCIH]^[NCCIH]
