Effects of a standardized saffron extract (Safr'Inside™) on menopause-related symptoms: a randomised, double-blind, placebo-controlled trial in perimenopausal women
In a randomized, double-blind, placebo-controlled trial involving 104 perimenopausal women, a 12-week treatment with a standardized saffron extract (Safr'Inside™) significantly reduced the severity of menopausal symptoms, particularly psychological and somatic disturbances, compared to placebo.

For many women, the years leading up to the permanent end of menstruation are marked by a complex shift in how they feel, both physically and emotionally. This transitional phase, known as perimenopause, is driven by fluctuating hormone levels that can ripple through the body's systems. It often brings a constellation of challenges: sudden waves of heat, sleepless nights, and a sense of unease or sadness that can weigh heavily on daily life. While hormone therapy exists, many women seek other ways to manage these symptoms, turning their attention to the natural world for answers. Among the many plants studied for their calming properties, saffron has long held a reputation for lifting spirits, but scientists have needed to test whether a specific, standardized version of this spice could genuinely help women navigating this difficult biological transition.
A recent clinical trial set out to test exactly this question. Researchers recruited one hundred and four healthy women who were in the thick of perimenopause, averaging forty-six years of age. These participants were divided into two groups and followed for three months. One group took a daily dose of a standardized saffron extract called Safr'Inside, while the other took a placebo, a harmless substance that looked and tasted identical but contained no active ingredients. Neither the women nor the doctors knew who was taking which until the study concluded. The goal was to see if the saffron could reduce the severity of menopausal symptoms, improve mood, and restore better sleep, all without the use of hormones.
The results were striking. By the end of the twelve-week period, the women who took the saffron extract reported a dramatic reduction in their overall symptom burden. Their scores on a standard scale measuring menopausal distress dropped by sixty-eight percent, a change that was far more significant than the modest seventeen percent reduction seen in the placebo group. This improvement was not limited to just one area of their lives; it touched the psychological and physical aspects of their experience. The women taking saffron felt noticeably less anxious and less depressed. They also reported fewer physical aches and pains that often accompany this life stage. These benefits appeared as early as six weeks into the study and continued to grow stronger by the final visit.
Sleep, too, saw meaningful changes. While the overall sleep score did not change drastically for everyone, the saffron group specifically reported feeling that their sleep quality was better and that they were less impaired by tiredness during the day. They also experienced a significant reduction in night sweats, the drenching episodes of heat that often wake women up in the middle of the night. However, the treatment did not appear to stop the classic hot flashes that occur during the day, suggesting that the extract works differently on these two related but distinct symptoms. Beyond the physical symptoms, the women felt a lift in their general well-being. They reported having more energy, feeling more emotionally stable, and engaging more easily with their social lives.
The study also looked at the safety of the treatment. The saffron extract was well tolerated, with very few side effects reported, and those that did occur were mild, such as occasional stomach upset. Crucially, the researchers found that the supplement did not alter the women's hormone levels in the blood, nor did it change their blood sugar or cholesterol in a way that would be immediately obvious. This suggests that the relief came not from replacing missing hormones, but perhaps from helping the brain and body manage stress and mood more effectively. The findings point to a promising, non-hormonal option for women seeking to navigate the perimenopausal years with greater comfort and clarity, offering a path forward that addresses the emotional and physical weight of the transition simultaneously.
