Also relevant for fibromyalgia patients with sleep disturbance, and adults seeking an alternative to melatonin that works through a different upstream pathway.

Which Supplement Is Best for Sleep Quality?

3 products ranked

Ashwagandha

Strong Evidence

Sensoril ashwagandha improved PSQI sleep scores in a 10-week placebo-controlled trial. Evening dosing targets GABA-A pathways — different from morning cortisol use.

L-Theanine

Moderate Evidence

Find the best L-theanine for sleep in 2026. We compare 3 clinically-dosed, third-party tested options for racing-mind insomnia and stress-related sleep issues.

3 products ranked

Magnesium

Moderate Evidence

Not all magnesium forms reach the brain. We compare glycinate, L-threonate, and citrate for sleep quality, cover the evidence behind each, and recommend doses by goal.

4 products rankedSleep, stress & muscle health

Melatonin

Limited Evidence

5mg and 10mg melatonin gummies cause grogginess because melatonin is a timing signal, not a sedative. We compare 0.3mg, 1mg, and 3mg using dose-response evidence.
