What the research shows.

Meta-analysis of 19 RCTs (n=1,683) examining melatonin for primary sleep disorders. Melatonin significantly reduced sleep onset latency by 7.06 minutes (p<0.001), increased total sleep time by 8.25 minutes (p=0.013), and improved overall sleep quality (p<0.001) versus placebo. Higher doses and longer durations showed greater effects.Ferracioli-Oda et al., PLoS ONE, 2013
Dose-response meta-analysis of 26 RCTs (n=1,689) optimizing melatonin as a sleep-promoting agent. Sleep onset latency reduction and total sleep time increase peaked at 4 mg/day. Administration 3 hours before desired bedtime was significantly more effective than the standard 30-minute pre-bedtime dosing (p=0.023).Scarpelli et al., Journal of Pineal Research, 2024
