While PMS is more common before menopause, magnesium is still valuable in perimenopause and beyond.
Magnesium’s Role
- Relaxes muscles and eases cramps.
- Regulates serotonin, reducing irritability and anxiety.
- Improves sleep quality and stress resilience.
- Reduces bloating and water retention.
Best Forms
- Magnesium glycinate: Calming, gentle, great for sleep.
- Magnesium citrate: Supports digestion, may ease constipation.
✅ Bottom line: Magnesium can ease PMS symptoms, perimenopausal mood swings, and sleep problems. Most women benefit from 300–400 mg/day with food.
