Hot flushes, mood swings, night sweats, and the occasional urge to cry because the Wi-Fi is slow — welcome to menopause! For many, it’s a hormonal rollercoaster complete with surprise heatwaves and emotional plot twists. But in recent years, a small but mighty plant compound has been making waves in the world of menopause management: soy isoflavones.
So, What Are Soy Isoflavones?
Soy isoflavones are a type of phytoestrogen — plant-based compounds that mimic the effects of oestrogen, albeit in a gentler, less aggressive way. Think of them as oestrogen’s chill cousin who shows up late to the party but still brings snacks.
Found in soybeans and soy products like tofu, tempeh, soy milk, and edamame, these compounds have a knack for binding to oestrogen receptors in the body. And during menopause — when oestrogen levels are taking a permanent sabbatical — these plant oestrogens may help fill in some of the hormonal gaps.
The (Hot) Flush with Science
Several studies have looked at soy isoflavones and their effects on vasomotor symptoms — the technical term for hot flushes and night sweats. While results vary (and science is rarely 100% unanimous), many findings suggest that regular consumption of soy isoflavones can reduce the frequency and severity of hot flushes.
Translation: fewer spontaneous internal heatwaves, less sweating through the bedsheets, and more chances of wearing a sweater in public without regretting every life decision.
Mood Swings & More: Soy’s Other Tricks
Menopause isn’t just about feeling like a baked potato under a heat lamp. There’s the emotional turbulence, the sleep disruption, the mystery aches, and the where-did-my-libido-go moments.
Here’s what soy isoflavones may help with:
Mood Swings: While not a cure-all, some evidence suggests soy can have a mild stabilizing effect on mood, likely due to its gentle hormonal influence.
Bone Health: Soy isoflavones may help reduce bone density loss, which becomes a bigger risk post-menopause.
Vaginal Dryness: The research here is mixed, but some studies have seen improvement with long-term soy intake.
Any Downsides to the Bean Dream?
Like any supplement or dietary shift, soy isn’t a miracle cure — and it’s not for everyone. Those with soy allergies should obviously steer clear. And anyone with a history of thyroid issues need guidance on whether soy isoflavones are suitable. And anyone with a history of oestrogen-sensitive conditions (like certain breast cancers) should check in with a healthcare provider before adding soy isoflavones to the menu.
It’s also worth noting that results aren’t instant. Improvements often take several weeks of regular consumption. This isn’t fast food — it’s slow-burn bean power.
How to Get More Soy Without Turning Into a Tofu Block

Swapping dairy milk for soy milk in coffee, cereal, or smoothies
Adding tofu or tempeh to stir-fries and salads
Snacking on edamame (bonus: they’re fun to eat)
