Ranked by evidence
Best supplements for menopause symptoms
For moderate to severe hot flushes, hormone therapy is far more effective than any supplement, cutting frequency by roughly 75%. The supplements below give modest reductions that take 8–12 weeks to show, and they are ranked by the grade of the evidence for symptoms rather than by popularity. Discuss any phytoestrogen with your oncologist if you have a history of hormone-sensitive cancer.
Picks are ranked by the strength of published evidence for this goal in otherwise healthy adults. A persistent symptom needs a clinician's evaluation, and no supplement on this list replaces treatment.

Solid options
| Option | Evidence | Best for | The honest note | |
|---|---|---|---|---|
| Soy Isoflavones | Moderate evidence | hot flush frequency and severity | Supplements providing at least 54 mg/day of genistein reduced hot flash frequency by about 21% and severity by about 26% more than placebo. Allow 8–12 weeks, and take levothyroxine at least 4 hours apart. | View |
| Siberian Rhubarb (ERr 731) | Moderate evidence | overall menopause symptom scores | The standardised ERr 731 extract lowered Menopause Rating Scale scores by about 15 points in a meta-analysis of 4 trials. All the evidence concerns this one extract from manufacturer-linked investigators, and generic Siberian rhubarb products are not the same preparation. | View |
| Genistein | Moderate evidence | hot flushes plus bone density | Isolated genistein reduced hot flash frequency in a multi-centre placebo-controlled trial and has moderate evidence for small gains in bone density. The effect is smaller than with hormone therapy. | View |
| S-Equol | Moderate evidence | women who do not make equol | The soy metabolite that only about a third of people produce reduced hot flashes in a meta-analysis, modestly and from few trials. The benefit may be clearest in women who cannot make equol from soy themselves. | View |
| Pollen Extract (Femal/Serelys) | Moderate evidence | a non-hormonal option | The purified pollen extract reduced hot flash frequency versus placebo in a small, mostly manufacturer-funded set of trials. It is not hormonal, which is why it is sometimes considered after breast cancer, though long-term safety data are limited. | View |
Popular for this goal — but the evidence says skip
- Black Cohosh Limited evidence
The Cochrane review of 16 trials in 2,027 women found no difference from placebo for hot flushes, and rare liver injury has led to regulatory label warnings.
- Red Clover Limited evidence
Pooled trials show one to two fewer flushes per day at best, which sits at the edge of what women would notice.
- Dong Quai Limited evidence
In the key placebo-controlled trial of 71 women, dong quai alone did no better than placebo for hot flashes, and it can raise INR in people on warfarin.
- Wild Yam Limited evidence
The body cannot convert its diosgenin into progesterone, and the one controlled trial found no effect on symptoms or hormones.
- Evening Primrose Oil Limited evidence
A small trial of 56 women found lower hot flash intensity but no change in frequency or duration, and it has not been convincingly replicated.
- Menopause Formulas Limited evidence
The blends are almost never tested as sold, usually underdose the ingredients that have evidence, and often contain black cohosh or St John's wort.
Our verdict
If you want a supplement, soy isoflavones providing at least 54 mg/day of genistein have the broadest evidence, and the Siberian rhubarb extract ERr 731 is a reasonable alternative. Skip black cohosh, which did no better than placebo in a Cochrane review, and the multi-herb menopause blends.
