What perimenopause actually is
Perimenopause is the transition leading up to your final period. It can begin in your late thirties or forties and often lasts four to eight years. Hormone levels do not simply decline in a straight line, they fluctuate, which is why symptoms can be unpredictable from one month to the next.
Common experiences include irregular cycles, hot flushes and night sweats, disturbed sleep, mood changes, joint aches, brain fog, and vaginal dryness or urinary changes. All of these are recognised, and none of them mean you are simply expected to cope.
The honest answer on supplements
If you are searching for a supplement for menopause in Singapore, here is the straight version: no supplement is a treatment for menopause. For hot flushes and night sweats specifically, menopausal hormone therapy remains the most effective option available, and that is a conversation for your doctor.
Supplements sit in a different category. Some have reasonable evidence for particular symptoms, some have weak evidence, and some are marketed far beyond what the research supports. Knowing which is which is the useful part.
Soy isoflavones: modest, and not for hot flushes
A 2025 systematic review and meta-analysis in PeerJ pooled seven studies covering 533 participants. It found a small overall improvement in menopausal symptoms (Hedges' g = −0.25, 95% CI −0.42 to −0.08), with a larger signal for depressive symptoms.
Importantly, it found no significant effect on hot flushes, insomnia or vasomotor symptoms. The authors were explicit that small effect sizes, wide confidence intervals and methodological inconsistency limit the certainty of the findings.
This matters because soy isoflavones are frequently marketed for hot flushes. The strongest recent pooled evidence does not support that specific claim.
Bone health: the part with the least controversy
Bone loss accelerates around menopause because oestrogen is protective of bone. Adequate calcium and vitamin D intake supports bone health, and this is standard, uncontroversial guidance rather than a fringe claim. In Singapore, vitamin D insufficiency is more common than people assume despite the climate, largely because of indoor lifestyles and sun avoidance.
Resistance and weight-bearing exercise does more for bone than any capsule. If you change one thing, change that.
Herbal supplements: promising in places, thin overall
A 2026 systematic review of non-soy oral herbal supplements concluded that certain herbs may have potential for some menopausal symptoms, particularly vasomotor symptoms, sleep and quality of life. The wording is deliberately cautious, and so is ours. Evidence varies considerably by herb and by outcome, and quality is inconsistent.
What has better evidence than most supplements
A 2025 systematic review of randomised controlled trials found exercise meaningfully improves perimenopausal symptoms. Sleep, strength training, protein intake and alcohol reduction are unglamorous and they outperform most of the supplement aisle.
How to read a menopause supplement label
- Match the claim to the symptom. Evidence for mood is not evidence for hot flushes. They are studied separately.
- Check the dose against the studies, not against the marketing.
- Be wary of percentages without a source. If a product advertises a dramatic figure, ask which trial it came from and how many people were in it.
- Consider interactions. Phytoestrogens are not automatically appropriate for everyone, particularly with a history of hormone-sensitive cancer, thyroid conditions, or while taking tamoxifen or anticoagulants.
When to see a doctor rather than buy a supplement
Please speak to a clinician if you have bleeding between periods or after sex, very heavy bleeding, any bleeding after twelve months without a period, symptoms severely affecting work or relationships, low mood or anxiety that is not lifting, or recurrent urinary symptoms. These deserve assessment, not a supplement.
The short version
Supplements can play a supporting role for some symptoms in some people. They are not a substitute for medical care, and the honest evidence for the symptom most women want help with, hot flushes, is weaker than the marketing suggests. Anyone who tells you otherwise is selling rather than informing.
