Menopause supplements and herbal remedies: evidence and safety
The market for menopause supplements is large, and claims often outpace evidence. Some products have been studied, with inconsistent or weak results, and a few carry safety concerns. This guide summarises what is known so that you can weigh up what to take and what to discuss with a pharmacist or clinician.

Key facts
At a glance.
-
Evidence
NICE says there is uncertainty about the efficacy and safety of complementary therapies for menopause symptoms.
-
Quality varies
Herbal products are not all regulated like medicines, and content and strength can vary between brands.
-
Liver concerns
Black cohosh has been linked to rare reports of liver damage, and the MHRA has issued advice.
-
Interactions
St John's wort interacts with many medicines, including contraceptives, anticoagulants and antidepressants.
How to read the claims
Trials of supplements for hot flushes often have high placebo response rates, because flushes vary and expectation influences how bothersome they feel. Small studies with short follow-up are common. Phrases such as "clinically proven" or "natural hormone balance" should be examined carefully. A product being plant-derived does not mean it is safe or effective.
What is known about common products
| Product | Evidence summary | Safety notes |
|---|---|---|
| Black cohosh | Mixed results; no consistent benefit across trials | Rare liver injury reports; avoid if you have liver disease |
| Red clover and soy isoflavones | Small or inconsistent effect on hot flushes in some trials | Plant oestrogens; discuss if you have had hormone-sensitive cancer |
| Evening primrose oil | No clear benefit shown for hot flushes | Can interact with some medicines |
| Vitamin E | Little evidence of meaningful benefit | High doses may carry risks |
| St John's wort | Some evidence for mild mood symptoms and possibly flushes | Many significant drug interactions |
| Ginseng, sage, maca and others | Limited or low-quality evidence | Product content and quality vary |
What to look for if you choose to try one
Look for the Traditional Herbal Registration mark on herbal products sold in the UK, which indicates that the product meets quality and safety standards, although it does not prove effectiveness. Choose one product at a time, for a defined trial of around three months, and keep a symptom diary. Stop if you notice side effects. Avoid products that promise to replace HRT or that are sold with claims about curing menopause.
Interactions and cautions
Tell your GP, pharmacist and any specialist about supplements you take. Be particularly careful if you take tamoxifen or aromatase inhibitors, anticoagulants, antidepressants, immunosuppressants or contraceptives. Supplements may affect surgery and anaesthesia. If you have liver disease, hormone-sensitive cancer or a bleeding disorder, seek advice first.
Nutrients with a clearer role
Vitamin D, particularly in autumn and winter, and calcium from the diet support bone health, and are better supported than many menopause-specific products. A balanced diet with enough protein, fibre and omega-3-rich fish helps general health. If you suspect a deficiency, ask for testing rather than guessing.
Spending sensibly
Costs can mount, especially for packages of multiple products. Compare against evidence-based options such as HRT, CBT and lifestyle measures, which are available on the NHS. If a product does not help after a fair trial, stop it.
Talking to a pharmacist
Community pharmacists are an underused source of advice. Bring the product box or a photo of the label, and a list of your regular medicines. Ask whether it is licensed or registered, whether there are known interactions and what the evidence is. A pharmacist can also say if your symptoms deserve a conversation with a GP, for example if you are bleeding unusually, losing weight or feeling persistently low, rather than trying another supplement.
Frequently asked
Questions people ask.
Quick, plain-English answers to the questions we hear most.
-
Do any supplements reliably stop hot flushes?
No supplement has been shown consistently to do so. Results are mixed.
