Insomnia
Supplements studied for insomnia.
Overview
Insomnia has substantial supplement coverage (6 supplements, 117 studies). Melatonin, Valerian, and Magnesium share medium effect size, high evidence, very high trust, WA 72. Melatonin may shorten sleep onset by roughly 7–12 minutes and modestly extend sleep in adults. Valerian may improve perceived sleep quality over weeks without consistently increasing total sleep time. Magnesium may reduce time to fall asleep in some adults, especially in combinations.
Kava (WA 52; low effect size, high evidence, medium trust) and L-Tryptophan (WA 48; low effect size, medium evidence, medium trust) have limited or mixed trial results. See the heatmap and evidence reviews below for dose and population details.
