What is the difference between menstrual cramps and PMS?

Menstrual cramps (dysmenorrhoea) are pain occurring during menstruation, primarily caused by prostaglandin-driven uterine contractions. Premenstrual syndrome (PMS) refers to physical and emotional symptoms in the luteal phase (7–14 days before menstruation) — including bloating, breast tenderness, mood changes, irritability, and fatigue — that resolve with the onset of menstruation. They often co-occur but have different mechanisms and management strategies.

What helps with both period pain and PMS?

Magnesium supplementation has evidence for both PMS mood symptoms and cramping. Vitamin B6 has evidence specifically for PMS mood symptoms. Acupuncture addresses both dysmenorrhoea and PMS. Regular aerobic exercise reduces PMS severity. Reducing caffeine, alcohol, and salt in the luteal phase can reduce bloating and mood symptoms. Anti-inflammatory nutrition supports both conditions.

Is there a hormonal explanation for severe PMS?

PMS is driven by the normal hormonal fluctuations of the menstrual cycle — but in some women, the sensitivity to these fluctuations (rather than the hormone levels themselves) is significantly heightened. Severe PMS (PMDD — premenstrual dysphoric disorder) involves profound mood disruption and warrants specialist assessment. Low progesterone relative to oestrogen in the luteal phase is often addressed clinically through nutritional, herbal, and in some cases hormonal approaches.

Can a nutritional therapist help with PMS and period pain?

Yes — nutritional approaches targeting magnesium, B vitamins, omega-3s, zinc, and anti-inflammatory diet patterns have a meaningful evidence base for both conditions. A nutritional therapist can also assess whether hormonal patterns, blood sugar dysregulation, or nutritional deficiencies are contributing, and design an individual protocol.
