Supplements for Irregular Periods: Vitex, Inositol and Herbal Formulas
Irregular periods have many causes, including stress, weight changes, thyroid problems and polycystic ovary syndrome (PCOS). Women often look at vitex, inositol and traditional herbal formulas. Our top picks cover all three. Supplements do not fix an underlying condition, so periods that are missed for three months, or new irregularity, should be checked.

How to Choose
Choose based on what you know. If a doctor has mentioned PCOS, inositol is the product most often discussed. If cycles are irregular after stress or weight change, vitex or a herbal formula may be considered. Keep a period diary. Try one product for at least three months and stop if periods become heavier or more painful.
What Are Irregular Periods?
A typical cycle is 21 to 35 days. Periods are considered irregular when the length varies widely, when they are missed, or when bleeding is unusually heavy or light. Causes include PCOS, thyroid disease, stress, sudden weight loss or gain, heavy exercise, perimenopause, breastfeeding, and some medicines.
When to See a Doctor
See a doctor if you miss periods for three months (and are not pregnant), have very heavy bleeding, bleeding between periods or after sex, severe pain, signs of excess hair growth or acne, or you are trying to conceive. Take a pregnancy test if a period is late.
What Supplements Can and Cannot Do
Some women find these products a comfortable addition while they work on sleep, stress and weight. Evidence varies, results differ, and no supplement is proven to regulate periods in every woman. Supplements do not treat PCOS, thyroid disease or other causes.
Precautions and Interactions
- Vitex (chasteberry) should not be combined with hormonal contraceptives, HRT, fertility drugs or dopamine-related medicines.
- Do not use herbal formulas in pregnancy or while breastfeeding. Take a pregnancy test if a period is late.
- Inositol: speak to a doctor first if you take diabetes medicines or lithium.
- Stop use if bleeding becomes heavier or you feel unwell.
