Why Saffron for Sleep
Saffron plays a supporting role in sleep. Saffron extract (Crocus sativus) standardized to safranal and crocins shows moderate-to-large effect sizes for depression and anxiety symptoms in meta-analyses of RCTs. Some trials show non-inferiority to SSRIs.
What dose to look for
Clinical studies typically use 28–30 mg of saffron. Most RCTs use 30mg/day standardized extract (e.g. affron®). Meta-analyses confirm efficacy at this dose for mood and anxiety. Products below this range may not deliver meaningful results.
What the research says

Clinical research on Saffron (Crocus sativus)
MODERATE — Meta-analysis of 8 RCTs (611 participants), multiple positive trials · 28–30 mg/day standardized extract (≥2% safranal, ≥10% crocins)
- •2022 meta-analysis of 8 RCTs (611 participants) found saffron significantly improved PSQI and Insomnia Severity Index scores vs placebo.
- •2023 systematic review of 5 RCTs (379 participants) confirmed beneficial effects on sleep duration and quality, with crocin and safranal inducing hypnotic effects.
- •2025 RCT (165 adults with moderate insomnia): 20–30 mg/day saffron extract for 4 weeks improved sleep quality in a decentralized, double-blind, placebo-controlled trial.
- •2025 RCT in healthy older adults: standardized saffron extract improved subjective and objective sleep quality measures.
- •Key limitation: most positive trials use branded extracts (affron®). Mechanism likely involves serotonergic modulation (serotonin → melatonin pathway) and GABAergic activity of crocins.
