PMS Symptom Relief
Relief from premenstrual symptoms including mood swings, bloating, and discomfort.
TL;DR
Calcium and vitamin B6 have the strongest PMS evidence, with chasteberry (vitex) best for breast tenderness and irritability. Track symptoms across two cycles first — if they are severe and mood-dominant, that is PMDD and needs different treatment.
Why It Matters
PMS symptoms arise in the luteal phase from altered sensitivity to normal progesterone metabolite fluctuations, not from abnormal hormone levels — which is why hormone testing is rarely useful. Premenstrual dysphoric disorder (PMDD) is the severe form, affecting 3-8% of menstruating people, and responds well to SSRIs (including luteal-phase-only dosing) and to hormonal suppression. Distinguishing PMS from PMDD is the most clinically important step.
How to Measure
Biomarkers
Optimization Protocol
1) Track symptoms prospectively for two cycles — retrospective recall is unreliable and this distinguishes PMS from PMDD and from underlying mood disorders. 2) Calcium 1000-1200mg/day has the best trial evidence for overall PMS symptom reduction. 3) Vitamin B6 50-100mg/day helps mood symptoms; do not exceed 100mg/day due to neuropathy risk. 4) Chasteberry (vitex) 20-40mg/day standardised extract is best supported for breast tenderness and irritability. 5) Magnesium 200-300mg/day for bloating and cramping. 6) Regular aerobic exercise, reduced alcohol and consistent sleep all reduce symptom severity. 7) If mood symptoms are disabling, discuss SSRIs — they work quickly in PMDD.
Lifestyle Levers
- •Symptom tracking across cycles
- •Aerobic exercise
- •Alcohol reduction
- •Consistent sleep
- •Reduced sodium in the luteal phase
- •Stress management
Supporting Supplements
Calcium
Calcium has the strongest randomised evidence of any supplement for overall PMS symptom reduction.
Vitex (Chasteberry)
Chasteberry is the best-supported option specifically for breast tenderness and premenstrual irritability.
Evening Primrose Oil
Evening primrose oil is popular for PMS but the trial evidence for general symptoms is largely negative.
Magnesium
Magnesium helps bloating, cramping and fluid retention, and pairs well with B6.

Frequently Asked Questions
Typical Timeframe
Calcium and B6 need 2-3 cycles. Chasteberry typically requires 3 cycles. SSRIs in PMDD can work within the first luteal phase.
