Melatonin
Melatonin is a hormone that regulates sleep-wake cycles, used as a supplement to improve sleep quality and treat insomnia.
Melatonin is a hormone naturally produced by the pineal gland that helps regulate the sleep-wake cycle.
As a supplement, it supports sleep onset, jet lag recovery, and overall circadian rhythm balance.
Melatonin is generally safe for short-term use and is popular in sleep aids and nighttime wellness products.
Other names & forms of Melatonin supplement : n-acetyl-5-methoxytryptamine, sleep hormone, melatonin supplement

Studies
These studies provide scientific insights into Melatonin benefits:
A 2013 meta-analysis of 19 RCTs found melatonin significantly reduced sleep onset latency by 7.9 minutes and improved total sleep time by 8.1 minutes versus placebo in primary insomnia.
A 2000 double-blind RCT in 60 elderly insomniacs showed 2 mg controlled-release melatonin for 4 weeks increased sleep efficiency by 12 % and total sleep time by 24 minutes versus placebo.
A 1987 crossover study of 0.5 mg melatonin versus placebo in 20 airline cabin crew flying eastward demonstrated reduced subjective jet‐lag scores and improved daytime alertness.
A 2000 randomized trial in 35 Alzheimer’s patients found 5 mg melatonin nightly for 12 weeks improved sleep efficiency by 14 % and reduced nocturnal awakenings versus placebo.
