Melatonin Benefits, Dosage & Side Effects Supplement Information and Usage Guide

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.

Studies

These studies provide scientific insights into Melatonin benefits:

A 2013 meta-analysis of 19 RCTs found melatonin (0.3–10 mg) significantly reduced sleep onset latency by 7.9 minutes (95 % CI: 4.5–11.3) and improved total sleep time by 8.1 minutes versus placebo in primary insomnia (P < 0.001).

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 (P < 0.01).

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 (P < 0.05).

A 2000 randomized trial in 35 Alzheimer’s patients found 5 mg melatonin nightly for 12 weeks improved sleep efficiency by 14 % (P < 0.01) and reduced nocturnal awakenings versus placebo.
