In a 28-day randomized, double-blind, placebo-controlled trial, 63 healthy participants took 28 mg of saffron extract (Crocus sativus L. and standardized to contain more than 3.5% Lepticrosalides) or placebo daily.
Funding issues for this study:
The primary outcome was insomnia severity according to the Insomnia Severity index, and there was a greater improvement in the saffron group. There wasn't a difference in the change in total sleep time or sleep latency, while the number of awakenings was lower and overall subjective sleep quality was higher. There wasn't a difference in mood open awaking, but alertness was improved, and participants reported more restorative sleep subjectively.
Adverse events weren't notably different.
