The uncomfortable headline first: of all the non-hormonal options studied for menopause symptoms, the one with the most consistent evidence isn't a supplement at all. It's cognitive behavioural therapy, which has been shown to reduce the impact of hot flushes and sweats as well as low mood and anxiety (Women's Health Concern / British Menopause Society).
That's not what the supplement aisle suggests. This guide goes through what the evidence actually supports.
Key takeaways
- Unregulated herbal remedies shouldn't be assumed safe. NICE's message is that potency and effectiveness vary widely, and interactions can be significant (WHC/BMS).
- Look for the THR logo. Traditional Herbal Registration means the dose, quality and product information have been checked (WHC/BMS).
- Black cohosh may help hot flushes, but not as well as HRT — and not at all for mood (WHC/BMS).
- Ginseng and Chinese herbal medicines haven't been shown to work for flushes, anxiety or low mood (WHC/BMS).
The regulation problem, before the individual products
This matters more than any single supplement. Herbal remedies that aren't regulated by a medicines authority should not be considered safe by default: there is wide variation in effectiveness and potency between products, and some carry significant side effects or interactions with prescribed medicines (WHC/BMS).
The practical shortcut is the THR logo — Traditional Herbal Registration. Products carrying it have been approved, so you can be confident the dosage is correct, the quality is controlled and the product information is accurate. Two bottles of the same herb, one with THR and one without, are not equivalent purchases (WHC/BMS).
"Natural" is a marketing word, not a safety category.
What the evidence says, product by product
| Evidence for symptoms | Cautions | |
|---|---|---|
| Black cohosh | Can help hot flushes, though less effectively than HRT. Does not help anxiety or low mood | Interacts with some medicines; safety risks not fully known. Usually avoided after breast cancer |
| St John's Wort | Shown to benefit hot flushes and sweats, including in women with or at high risk of breast cancer | Interacts with many drugs. Not for women on tamoxifen — it can make tamoxifen less effective |
| Isoflavones / soya / red clover | Study results are variable. Women whose normal diet is already high in them should carry on as usual | Not recommended for women with breast cancer |
| Ginseng | Not shown to improve hot flushes, anxiety or low mood | — |
| Chinese herbal medicines | Not shown to improve hot flushes, anxiety or low mood | Unregulated products carry interaction risk |
| Acupuncture | Women often report fewer flushes, but trials show no difference between real and sham acupuncture | Low risk; the benefit may come from the therapeutic relationship |
All of the above is drawn from the British Menopause Society's summary of the NICE NG23 evidence review (WHC/BMS; NICE NG23).
What about magnesium, vitamins and "perimenopause complexes"?
These are heavily marketed and thinly evidenced. They don't appear in the NICE network meta-analysis of menopause treatments, which compared placebo, acupuncture, hormonal options, isoflavones, Chinese herbal medicine, black cohosh, multi-botanicals and CBT (WHC/BMS).
That doesn't make them harmful, and correcting a genuine deficiency is worthwhile — but "supports hormonal balance" on a label is not a claim anyone has had to prove. If you're spending £30 a month on a perimenopause complex and your symptoms haven't shifted, the evidence would not predict that they should.
If you suspect a deficiency, a blood test answers the question properly. Our full body health check covers the common ones.
The option with the best evidence
Cognitive behavioural therapy. It can reduce low mood and anxiety arising from menopause, and also reduce the impact of hot flushes and sweats — and it's now a recommended treatment option for anxiety during peri- and postmenopause (WHC/BMS).
The approach that works combines relaxation techniques, sleep hygiene and reframing how you relate to symptoms. In England you can self-refer to NHS Talking Therapies without going through a GP.
There are also several non-hormonal prescription options used for flushes and sweats, including newer agents approved for NHS use. Whether any of them suits you is a clinical decision made with a prescriber after assessing your symptoms and history — not something to select from a list (WHC/BMS).
Lifestyle measures worth the effort
The NHS suggests regular exercise, a healthy balanced diet, reducing caffeine and alcohol, stopping smoking, and techniques such as yoga or relaxation for menopause symptoms (NHS).
These are unglamorous and genuinely useful, and unlike most supplements they're free.
When to see a GP
See a GP or a menopause clinician if symptoms are affecting your daily life, if you want to discuss treatment options, or before starting a herbal supplement if you take any prescribed medicine — interactions are the most common avoidable problem here (WHC/BMS).
Anyone who has had breast cancer, or is at high risk, should get menopause advice from a clinician with specific expertise in it (WHC/BMS).

Honest FAQs
What are the best supplements for perimenopause?
There isn't a clear winner, which is the honest answer. Black cohosh has some evidence for hot flushes but not for mood, and St John's Wort has evidence for flushes but interacts with many medicines (WHC/BMS). Neither is a general-purpose menopause supplement.
Does magnesium help menopause symptoms?
It isn't among the treatments NICE assessed for menopause symptoms, so there's no strong evidence base to point to. Treating a diagnosed deficiency is reasonable; taking it as a menopause remedy is not well supported.
Are natural remedies safer than HRT?
Not automatically, and this is the most common misconception. Unregulated herbal products vary in potency and can interact significantly with prescribed medicines (WHC/BMS).
Can I take supplements alongside HRT?
Ask the clinician who prescribed your HRT first. The issue is interactions rather than the combination itself, and it depends on the specific product.
Does acupuncture work for hot flushes?
Women often report improvement, but trials comparing real acupuncture with sham acupuncture show no difference between them (WHC/BMS).
What if I've had breast cancer?
Get advice from a clinician with menopause expertise. Black cohosh, isoflavones and red clover are generally not recommended, and St John's Wort must be avoided with tamoxifen (WHC/BMS).
