What should you know about vitamins for premenstrual syndrome?

PMS symptoms can include breast tenderness, bloating, cramps, headaches, tiredness and changes in mood. Their timing around the menstrual cycle is useful information, but it does not prove that a vitamin deficiency is the cause.

Calcium, magnesium, vitamin B6 and other products are often advertised for PMS. They differ in dose, ingredients and quality. Taking several products together can unintentionally increase the total amount, and some supplements affect medicines or are unsuitable with kidney, liver or pregnancy-related concerns.

Track symptoms, bleeding and the days they occur for several cycles. Discuss the record with a clinician before starting a supplement, particularly if symptoms are new, severe or changing. Choose a clearly labelled product and follow professional dosing advice rather than escalating because symptoms persist.

Regular meals, hydration, sleep, moderate activity and limiting alcohol may reduce the burden of symptoms. If breast pain is a major concern, use the dedicated Breast Pain information alongside a clinical assessment. A clinician may also discuss the Combined Pill or other options.

Arrange an appointment if symptoms disrupt work, study, relationships or routine activities, or if they do not follow a predictable cycle. Seek urgent help for thoughts of self-harm, fainting, severe abdominal pain, heavy unexpected bleeding or a serious reaction after taking a product.

Does my symptom pattern fit PMS or another condition? Should I check for a deficiency before taking a supplement? Could my current medicines interact with it? Which treatment is appropriate if symptoms continue despite lifestyle changes?
