Study Finds Saffron Extract May Improve Sleep Quality
Approximately 50 million Americans suffer from some type of sleep disorder and approximately 20 million suffer intermittent sleep problems each year. A new study suggests that saffron extract may help improve sleep quality in adults with self-reported sleep complaints.
Participants in the study included 63 healthy adults with an average age of 44 who had self-reported sleep problems. They received either 14 mg of saffron extract or a placebo twice daily for 28 days. Sleep quality was assessed at baseline, days 7, 14, 21, and 28 using the Insomnia Severity Index, the Restorative Sleep Questionnaire, and the Pittsburgh Sleep Diary.
Participants in the saffron group saw greater improvements in the Insomnia Severity Index total score, the Restorative Sleep Questionnaire total score, and the Pittsburgh Sleep Diary sleep quality ratings compared to the placebo group. The majority of improvements were seen in the first week.
The study was conducted by researchers from Murdoch University. It was published online ahead of print on February 14, 2020 in the Journal of Clinical Sleep Medicine.
