    Prices are the brand's UK list price at the time of writing and change often. Cost per day is calculated from pack size and the label's daily serving, and is shown only where the brand publishes both. We do not accept payment for inclusion or placement.

    When a supplement is not the answer

    PCOS needs a diagnosis, and it needs monitoring. Irregular or absent periods, unexplained weight change, significant acne or hair growth, difficulty conceiving, or a family history of type 2 diabetes all warrant a proper assessment rather than a supplement bought on the basis of a symptom checklist. Long-term, PCOS raises metabolic risk, and that is managed clinically.

    Speak to a clinician about PCOS

    Questions people ask.

    Which supplements for pcos should I buy?
    The PCOS supplement with the most trial evidence is myo-inositol, usually 4g daily in a 40:1 ratio with D-chiro-inositol, which improves insulin sensitivity and cycle regularity over three to six months. Vitamin D matters if you are low. Nothing cures PCOS, and supplements work alongside clinical care rather than replacing it.
    How is cost per day calculated?
    We divide the brand's UK list price by the number of days a pack lasts, using the pack size and the daily serving printed on the label. Where a brand does not publish both numbers we leave the figure blank rather than estimate it.
    Are these products ranked or paid placements?
    No. The table is ordered alphabetically and nobody pays to appear in it. We do not hold ratings, accreditations or trial results for individual products, so we do not publish any.
    Can I take more than one of these together?
    Often yes, but check the total dose of any nutrient that appears in more than one product, and check interactions with your medication with a pharmacist first. Iron in particular should only be taken when a blood test shows you need it.
    What is the best supplement for PCOS?
    Myo-inositol has the most trial evidence, typically 4g daily with 100mg D-chiro-inositol. Vitamin D is worth correcting if you are low.
    How long do PCOS supplements take to work?
    Metabolic markers can move in eight to twelve weeks; cycle regularity usually takes three to six months. Judge it at three months.
    Can supplements cure PCOS?
    No. Nothing cures PCOS. Inositol and lifestyle changes can meaningfully improve insulin sensitivity and cycle regularity, which improves symptoms.
