Nature's estrogen? soya bean put to the test for menopause relief
NCT ID NCT07739615
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This trial explores whether eating soya bean, a rich source of plant estrogens, can help relieve menopause symptoms and influence reproductive hormones. It will involve women over 40 who have not had a period for at least a year. The study will measure changes in hormone levels and track symptom improvements using questionnaires.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- soya bean (a dietary supplement rich in plant estrogens called phytoestrogens)
- What this could lead to
- If soya bean proves effective, it could offer a natural, hormone-free option for easing menopause symptoms, potentially reducing reliance on hormone replacement therapy.
- What could go wrong
- This is a small, early-stage trial, and previous studies on soya bean's effects have been inconclusive. Results may not apply to all women, and the supplement may not significantly change hormone levels or symptoms.
