Saffron, a spice derived from the Crocus sativus flower, has long been celebrated for its medicinal properties. Recent research has looked closely at its potential to improve mood and sleep in adults experiencing low mood. This blog summarizes the findings of a 12-week, randomized, double-blind, placebo-controlled study—the largest of its kind—examining the effects of saffron extract (Affron®) on mood and general well-being.
Why Saffron?
Saffron has traditionally been used to address various health issues, including mental health. Previous studies have shown that saffron can help with stress, mood, and sleep problems. This study aimed to expand on that evidence by focusing on adults with subclinical depression—those experiencing low mood but not diagnosed with major depressive disorder.
The Study Design
Researchers recruited 202 adults aged 18 to 70 who reported low mood. Participants were randomly assigned to take either saffron extract (28 mg daily) or a placebo for 12 weeks. The study assessed changes in mood, stress, anxiety, sleep quality, and overall well-being using validated questionnaires and daily mood ratings.
Key Findings
- Improved Mood: Saffron supplementation significantly decreased depressive symptoms compared to the placebo. Participants in the saffron group experienced a 53% reduction in depression scores, while the placebo group saw a 39% reduction. This confirms saffron’s potential as a natural mood booster.
- Stress Reduction: Although overall stress scores didn’t show significant differences between groups, saffron supplementation resulted in lower weekly stress ratings at specific time points (weeks 5, 10, and 12).
- Sleep Benefits: Participants with more severe sleep issues experienced notable improvements with saffron. Sleep disturbance scores decreased by 12% in the saffron group compared to 8% in the placebo group. Sleep-related impairment also improved, with a 15% decrease in the saffron group versus 11% in the placebo group.
- Wellbeing: Although improvements in overall wellbeing (measured by the WHO-5 scale) weren’t statistically significant, there was a trend favoring saffron.
- Safety and Tolerability: Saffron was well-tolerated, with no serious adverse effects reported. Over 95% of participants rated their tablet experience as good or excellent.
What Makes This Study Stand Out?
This research is the largest study ever conducted on saffron’s mood-enhancing effects. It also examined the benefits of saffron over a more extended period (12 weeks) compared to most previous studies, which usually lasted 4 to 8 weeks. Notably, the study focused on individuals with subclinical depression, a group often overlooked in clinical trials.
What’s Next?
While this study highlights saffron’s potential to improve mood and sleep, further research is needed to:
- Understand how saffron works to reduce depressive symptoms.
- Explore its effects on anxiety and stress in populations with more severe symptoms.
- Investigate whether saffron can enhance the effectiveness of antidepressant medications.
Takeaway
Saffron extract (Affron®) shows promise as a natural option for improving mood and sleep in adults experiencing low mood. With its excellent safety profile and increasing evidence of effectiveness, saffron could be a helpful addition to the toolkit for managing poor mood symptoms and sleep issues.
