The Claim
Soy isoflavone supplements reduce the severity of menopausal hot flashes by 26.2% compared to placebo, with a 95% confidence interval of -42.23% to -10.15%, in perimenopausal and postmenopausal women.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Soy isoflavone supplements reduce the severity of menopausal hot flashes by 26.2% compared to a placebo in perimenopausal and postmenopausal women.
See the scientific wording
Soy isoflavone supplements reduce the severity of menopausal hot flashes by 26.2% compared to placebo, with a 95% confidence interval of -42.23% to -10.15%, demonstrating a statistically significant effect in perimenopausal and postmenopausal women across 9 randomized controlled trials.
Soy isoflavones bind to estrogen receptors in the brain's temperature control center, which reduces false signals that the body is overheating, leading to fewer and less intense hot flashes.
What the research says
1 studyThis study found that women who took soy supplements had hot flashes that were about 26% less severe than those who took dummy pills, which matches exactly what the claim says.
