How Much Magnesium Per Day Over 70?
For women over 70, the general recommendation for magnesium is around 320 mg a day from all sources, most of it from food. Supplements usually add 100–350 mg — and the upper limit for magnesium from supplements alone is 350 mg a day. Magnesium helps muscles and nerves work as they should and contributes to reducing tiredness and fatigue. Food first, then a modest top-up.
How much magnesium do you need after 70?
The recommended intake for adult women is roughly 320 mg of magnesium a day, and that figure doesn't climb just because you're over 70. Most of it should come from food — wholegrains, nuts, seeds, beans, leafy greens and even dark chocolate are all rich sources. A supplement is there to close a gap, not to replace a varied diet. Magnesium helps muscles and nerves work the way they should, and it contributes to the reduction of tiredness and fatigue.
The upper limit to keep in mind
There's an important distinction here. That ~320 mg target is for magnesium from all sources, food included. But the upper limit that applies to magnesium from supplements alone is 350 mg a day. Go much beyond that and the usual result is loose stools or stomach upset, because unabsorbed magnesium draws water into the gut. This is why a sensible supplement sits comfortably under that ceiling rather than pushing it.
A note on sleep
Magnesium is often sold as a sleep aid, and it's fair to be clear: helping you sleep is not an approved health claim for magnesium, and the evidence is mixed. What magnesium is recognised for is helping muscles and nerves work as they should and helping reduce tiredness and fatigue. If sleep is a real problem after 70, it's worth a GP conversation rather than relying on a supplement to fix it.
Which form, and does it matter after 70?
Forms differ mostly in how gentle they are on the stomach. Magnesium bisglycinate and citrate tend to be better tolerated than magnesium oxide, which is more likely to cause loosening — a worthwhile consideration for older digestive systems. The amount of actual (elemental) magnesium is what counts, so check the label for that figure rather than the total weight of the compound.
Magnesium and medications — spacing matters
Magnesium can affect how some medicines are absorbed. It can bind certain antibiotics (like tetracyclines and fluoroquinolones) and interfere with thyroid medication (levothyroxine) if taken at the same time — so these are usually spaced a few hours apart. Because taking several medicines is more common after 70, ask your GP or pharmacist how to space a magnesium supplement around yours. Never adjust a prescription yourself.
