Taking Ashwagandha and melatonin together for two months reduces anxiety levels in adults with mild sleep problems more than taking either supplement alone or a placebo.

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 reduces anxiety symptoms in adults with sleep disturbance, independent of sleep improvement, across diverse populations.
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 HAM-A or GAD-7 as primary anxiety outcomes, with follow-up ≥8 weeks.
That the combination causally reduces anxiety symptoms in adults with sleep disturbance, independent of sleep outcomes.
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 HAM-A score and secondary outcomes including cortisol and actigraphy, to disentangle sleep and anxiety effects.
Whether long-term use of the combination is associated with sustained reductions in anxiety symptoms over 1–3 years in adults with sleep disturbance.
A prospective cohort study of 1,000 adults aged 18–60 with mild sleep disturbance, tracking daily use of Ashwagandha + melatonin versus non-use, with quarterly HAM-A assessments and adjustment for stress, sleep quality, and lifestyle factors over three years.
Whether responders to the combination with reduced anxiety differ in HPA-axis biomarkers (e.g., cortisol, ACTH) compared to non-responders.
A case-control study comparing 80 responders (≥5-point HAM-A reduction) to 80 non-responders after 8 weeks of Ashwagandha + melatonin, matched for baseline anxiety, analyzing serum cortisol at 8 AM and 8 PM, and ACTH levels.
The association between current use of Ashwagandha and melatonin and self-reported anxiety levels in adults with sleep disturbance.
A national survey of 5,000 adults aged 18–60 with self-reported sleep disturbance, assessing current use of Ashwagandha and melatonin and anxiety levels via HAM-A or GAD-7, adjusting for age, sex, and stress exposure.
