Taking Ashwagandha and melatonin together helps adults with mild sleep problems stay asleep longer and spend more time in actual sleep rather than lying awake at night, more than taking either supplement alone.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether Ashwagandha and melatonin combination consistently improves sleep maintenance (WASO, SE) across populations with mild-to-moderate sleep disturbance, independent of sleep onset effects.
A systematic review and meta-analysis of at least 10 RCTs comparing Ashwagandha (600 mg/day) + melatonin (3 mg/day) versus placebo or monotherapy in adults aged 18–60 with DSM-5-defined sleep disturbance, using actigraphy to measure WASO and SE as primary outcomes, with follow-up ≥8 weeks.
That the combination causally improves sleep maintenance in adults with mild-to-moderate sleep disturbance, independent of stress or circadian effects.
A double-blind RCT with 200 participants aged 18–60, randomized to Ashwagandha (600 mg/day) + melatonin (3 mg/day), Ashwagandha alone, melatonin alone, or placebo for 12 weeks, with primary outcomes being WASO and SE via actigraphy, and secondary outcomes including polysomnography to confirm sleep architecture changes.
Whether long-term use of the combination is associated with sustained improvements in sleep maintenance and reduced nocturnal awakenings over 1–3 years.
A prospective cohort study of 1,200 adults aged 18–60 with mild sleep disturbance, tracking daily use of Ashwagandha + melatonin versus non-use, with monthly actigraphy assessments of WASO and SE over three years, adjusting for stress, caffeine, and screen time.
Whether individuals who respond to the combination with improved sleep maintenance differ in GABAergic or serotonergic biomarkers compared to non-responders.
A case-control study comparing 80 responders (≥12 min WASO reduction) to 80 non-responders after 8 weeks of Ashwagandha + melatonin, matched for baseline sleep severity, analyzing serum GABA, 5-HT, and cortisol levels.
The association between current use of Ashwagandha and melatonin and self-reported frequency of nighttime awakenings in the general population.
A national survey of 5,000 adults aged 18–60 assessing current use of Ashwagandha and melatonin and frequency of nighttime awakenings via validated sleep questionnaires, adjusting for age, BMI, and alcohol use.
