Saffron Extract May Help Improve Sleep Quality
Saffron is a spice derived from the flower of Crocus sativus and has antioxidant properties. According to a recent study, saffron extract may help improve sleep duration and quality.
Participants in the study included 66 adults with mild to moderate sleep disorder. They received 15.5 mg of saffron extract or a placebo daily for 6 weeks. Sleep quality was assessed using the Leeds Sleep Evaluation Questionnaire and the Pittsburgh Sleep Quality Index at baseline, day 7 and day 42. Actigraphy was used to collect sleep data at baseline, week 3, and week 6.
Participants in the saffron extract group saw an increase in time in bed compared to the placebo group. They also saw improvements in ease of getting to sleep, sleep quality, sleep latency, and sleep duration, compared to no changes in the placebo group.
The study was conducted by researchers from the Université catholique de Louvain. It was published online ahead of print on April 27, 2021 in the journal Nutrients.
