Some supplements actually do, and it's worth knowing which ones and why.

The evidence map behind ashwagandha, saffron, and phosphatidylserine

Not every supplement women reach for during perimenopause has real research behind it. A few actually do, and it’s worth knowing which ones and why.

Ashwagandha

Ashwagandha has the most direct evidence. Several randomized, placebo controlled trials, including ones published in 2025, gave the herb specifically to perimenopausal and menopausal women and tracked real outcomes: fewer hot flashes, better sleep, lower stress scores, and measurable shifts in estradiol, FSH, and LH. One eight week trial using 300mg twice daily found significant improvement across psychological and physical menopause symptoms compared to placebo. This isn't folklore, it's been tested in the population it's meant for.

Saffron

Saffron has a similar track record, and it's newer. A 2025 trial gave a standardized saffron extract to 86 perimenopausal women for 12 weeks and found real gains in mood and quality of life over placebo. A follow up trial in women 50 to 70 went further, showing improvements in mood, sleep, and self esteem together, something researchers hadn't measured all at once before. The dose that keeps showing results is around 28mg a day.

Phosphatidylserine

Phosphatidylserine is the honest outlier here. It has solid research behind lowering the body's cortisol response to stress and supporting memory and attention. What it doesn't have yet is a body of trials done specifically in perimenopausal women, so its use in that context is a reasonable extrapolation, not a proven fit.

None of this replaces a conversation with your doctor, especially if you're on other medication. But it does mean you can ask better questions when you're standing in front of the supplement aisle.
