Why magnesium matters before your period
March 5, 2026 · by Feme Team
Magnesium is involved in more than 300 processes in the body — from muscle relaxation to blood sugar regulation to the making of serotonin. In the days before your period, when progesterone falls and PMS shows up, magnesium is one of the first minerals we run short on.
Low levels are quietly linked to cramps, restless sleep, sugar cravings and that tight, wired kind of mood. Topping it up won't fix everything, but it makes the come-down noticeably softer.
Food-first sources: dark leafy greens, pumpkin seeds, almonds, dark chocolate, black beans. If you supplement, magnesium glycinate is gentle on the stomach and kind to sleep.
