Evidence league table
Best perimenopause supplements in the UK
No supplement treats perimenopause. Graded on the evidence, the categories with an authorised regulatory claim and a real role are vitamin D, magnesium, omega-3 and, for active women, creatine, with iron only after a test. Collagen and herbal menopause blends have no authorised claim. Information only, not medical advice; speak to your GP or pharmacist.

The evidence league table
| Supplement | Evidence status | Effective daily dose | Cost per effective dose (illustrative) | What the evidence says, and source |
|---|---|---|---|---|
| Vitamin D | Authorised claim plus an active NHS recommendation | 10 mcg (400 IU) a day | 1p to 8p (per 10 mcg) | EFSA-authorised claims for normal bones and muscle function, and the NHS advises adults consider a daily 10 mcg supplement in autumn and winter, which matters more as bone density can decline through perimenopause. Source: NHS, Vitamin D |
| Magnesium | Authorised claim | 100 mg elemental (of the 270 mg daily reference intake) | 4p to 22p (per 100 mg elemental) | EFSA-authorised claims include contributing to normal muscle and nervous-system function and to the reduction of tiredness and fatigue. The NHS notes most people get enough from a balanced diet. Women 19 to 64 need 270 mg a day. Source: NHS, Others: vitamins and minerals (magnesium) |
| Omega-3 (EPA and DHA) | Authorised claim | 250 mg combined EPA and DHA a day | 3p to 25p (per 250 mg EPA + DHA) | EFSA-authorised claim that EPA and DHA contribute to normal heart function at a daily intake of 250 mg combined. Priced per that 250 mg, not per "1000 mg fish oil". Source: EFSA authorised claim, EPA and DHA (Regulation (EU) 432/2012) |
| Creatine | Authorised performance claim (active women) | 5 g monohydrate maintenance serving | 4p to 60p (per 5 g) | EFSA-authorised performance claim in the context of resistance training, at a daily intake of 3 g. Of most interest to active women maintaining strength; it is for adults and not recommended in pregnancy without medical advice. Source: EFSA authorised claim, creatine and physical performance |
| Iron | Authorised claim, but test first | 14.8 mg elemental a day (women 19 to 49) | 1p to 10p (per mg elemental) | EFSA-authorised claims for normal red-blood-cell formation and reduced tiredness. Relevant if perimenopausal periods are heavy, but the NHS advises a ferritin test before supplementing rather than routine use. Women 19 to 49 need 14.8 mg a day. Source: NHS, Iron |
| Collagen | No authorised health claim | 10 g hydrolysed-collagen serving | 20p to 120p (per 10 g serving) | There are 0 EFSA-authorised health claims for collagen, so promises about skin, hair or joints go beyond what the rules allow. Popular in this life stage, but priced here only per the 10 g serving used on labels, with no claim implied. Source: EFSA, Nutrition and health claims register |
| Ashwagandha | No authorised health claim | 600 mg standardised extract a day | 8p to 45p (per 600 mg extract) | A herbal supplement with 0 EFSA-authorised health claims, so any promise about stress or sleep goes beyond what the rules permit. Some phytoestrogen and herbal menopause blends are not suitable for everyone, so check the label and ask your pharmacist. Source: EFSA, Nutrition and health claims register |
Cost is the price of one effective dose of the active ingredient per day, as an illustrative UK range from a budget to a premium form (for example plain magnesium tablets versus a branded blend).

Also relevant, not in the priced table
Two more categories matter in perimenopause but are not priced above. Calcium works alongside vitamin D for normal bones, which is why both get attention as bone density can decline in this stage; most women can meet the NHS reference intake through diet. Protein contributes to maintaining muscle mass and normal bones, and muscle can become harder to hold onto around perimenopause, so protein and resistance training come up often. Neither is a symptom treatment.
Products sold specifically as menopause or perimenopause supplements often combine a few nutrients with herbal ingredients such as red clover, sage or other phytoestrogens. Many of the implied benefits are not authorised claims, and some phytoestrogens are not suitable for everyone, including some women who cannot take HRT. Treat these blends with the same scrutiny as any other product and discuss anything new with your GP or pharmacist. See supplements for menopause: what the evidence says.
How we ranked and priced these
Our methodology is disclosed and consistent, and we do not rank by affiliate commission or accept payment for a favourable placing. We grade each category first on regulatory evidence: whether a GB or EFSA-authorised health claim exists, and how the NHS frames the nutrient in this life stage. We then attach the effective daily dose, the amount of the active ingredient a named reference body actually talks about, taken from our Price-Per-Effective-Dose Index, and an illustrative UK cost for that dose. A high grade means the claim is authorised, not that you personally need the supplement.
A low cost per effective dose does not mean you should take something, and a high one does not mean you should not. Whether any supplement is right for you depends on your diet, symptoms and health, and the NHS advises most nutrients are best obtained from food. For symptom relief, the main evidence-based option is HRT, which is a conversation for your GP or a menopause specialist.

Frequently asked questions
What are the best supplements for perimenopause?
No supplement treats perimenopause. On the evidence, the categories with an authorised regulatory claim and a genuine role in this life stage are vitamin D and calcium for bones, magnesium, omega-3, and protein or creatine for maintaining muscle if you are active. Products sold specifically for menopause often imply benefits that are not authorised claims, so read labels and speak to your GP or pharmacist.
How did you rank this league table?
We ranked by regulatory evidence status first: whether an EFSA-authorised health claim exists, and how relevant the NHS considers the nutrient in perimenopause. We are not ranking by how well a product sells or by commission. Each row then shows the effective daily dose from an NHS or EFSA source and an illustrative cost per effective dose, so the cheap and the dear forms are visible side by side.
Do perimenopause supplements actually work?
They do not treat perimenopausal symptoms such as hot flushes; the strongest evidence for symptom relief sits with medical options like HRT, discussed with your GP. What some nutrients do is support general health that matters more in this stage, for example vitamin D and calcium for bones. That is a modest, general nutrition role, not a symptom cure.
Can I take perimenopause supplements with HRT?
Often, but it depends on the specific product and your medication, and some herbal ingredients in menopause blends can interact or are not suitable for everyone. This is a question for your GP or pharmacist, who can check your individual situation. Never stop or change prescribed treatment to take a supplement.
Are expensive menopause supplement blends worth it?
Not automatically. Many menopause-branded blends combine a few nutrients with herbal ingredients and charge a premium, while the nutrients with a real authorised role, such as vitamin D and magnesium, are cheap bought plainly. Our cost-per-effective-dose tools let you check whether you are paying for the active amount or for the branding.
This is information, not medical advice, and is not a substitute for a registered clinician. Supplements do not treat perimenopause. Always read product labels and speak to your GP or pharmacist before starting a supplement, especially if you take other medication or cannot take HRT.
