What magnesium may help with in menopause
Magnesium is involved in hundreds of body processes — including sleep, muscle and nerve function, blood sugar, and bone health — and many women in midlife don't get enough from food. That's why it's such a popular menopause supplement. Realistically, the evidence is strongest for sleep, mood and stress, muscle cramps, and bone support, and weakest for hot flashes, where data are limited. It won't fix everything, but it's low-risk and reasonable to try, especially if you struggle with sleep or constipation.
Which type of magnesium should you take?
| Form | Best for | Notes |
|---|---|---|
| Glycinate | Sleep, calm, general use | Gentle on the stomach; a common first choice |
| Citrate | Constipation | Well absorbed but has a laxative effect |
| Oxide | Constipation (cheap) | Poorly absorbed; mostly a laxative |
| Malate / threonate | Energy / brain (marketed) | Less evidence; usually pricier |
How much, and from food
The recommended intake for women is about 320 mg a day. Supplements typically provide 200–400 mg, but it's best to keep the supplemental amount under about 350 mg a day, because more than that commonly causes diarrhea. Food is the safest source — leafy greens, nuts, seeds, beans, whole grains, and dark chocolate are all rich in magnesium.
Safety
Magnesium is generally safe, but it can cause loose stools, may interact with certain medications (such as some antibiotics and bone drugs), and should be used cautiously if you have kidney disease — so check with a clinician if you take other medicines or have health conditions.
