In simple terms: a herbal supplement made from the fruit of the Vitex agnus-castus tree, also called chasteberry.

Why it matters for PCOS

Vitex is often marketed to support more regular periods and is sometimes used after stopping the contraceptive pill. Despite its popularity, it is not a standard treatment for PCOS and the scientific evidence for its effect in PCOS is limited. It does not replace doctor-confirmed steps such as lifestyle changes or prescription medicine.

Because it is a herb that can affect hormones, Vitex may not be suitable for everyone, especially if you are pregnant, breastfeeding, trying to conceive, or taking hormone-related medicine. Check with a doctor or pharmacist before trying it, and tell them about any supplements you take.
