How much magnesium per day for a woman over 50?
A woman over 50 needs 270mg of magnesium a day from all sources, the same as at 30 or 60. What changes is context: bone, muscle, medications and kidneys. A 300mg glycinate serving still fits, after a pharmacist check.

The number does not move; the reasons to meet it do
The UK reference nutrient intake for women is 270mg of magnesium a day from 19 onward with no upward step at 50, 60 or 70, so the over-50 and over-60 versions of this question share an answer: 270mg from food, water and any supplement combined. What changes after 50 is everything around that number. Menopause accelerates bone loss, and magnesium contributes to the maintenance of normal bones alongside the calcium and vitamin D that get the headlines. Muscle mass declines with age, sarcopenia, and the normal muscle function and protein synthesis claims describe machinery that resistance training and protein need working. Appetite and food volume often fall, squeezing the magnesium-rich foods, which is the same narrow-diet story this site tells lifters, arriving by a different road.
The context that raises the stakes: sleep, medicines, kidneys
Three age-linked realities deserve their own paragraph. Sleep: the small magnesium sleep trials, Abbasi's and Nielsen's, were run in adults over 51 with poor sleep and low intake, which makes this the one group where the modest evidence was actually generated; the honest expectation is still modest, and no sleep claim is authorised. Medicines: the chance of a spacing interaction rises with every prescription, levothyroxine and bisphosphonates being common after 50, and long-term proton pump inhibitors are the subject of a UK regulator warning for lowering magnesium over years, both reasons the pharmacist check moves from optional to routine. Kidneys: function declines gradually with age, and since magnesium clearance depends on it, anyone with reduced kidney function or a chronic kidney diagnosis should not start supplements without their clinician. None of this changes the 270mg; all of it changes how carefully the capsule is chosen.
| Consideration | The facts | What to do |
|---|---|---|
| Reference intake | 270mg a day, all sources, unchanged after 50 and 60 | Aim there from food first |
| Bone health | Magnesium supports normal bones; menopause speeds bone loss | Adequate magnesium alongside calcium, vitamin D and loaded exercise |
| Muscle | Normal muscle function and protein synthesis claims; sarcopenia risk rises | Resistance training and protein do the heavy lifting; magnesium keeps intake adequate |
| Sleep | Trials in over-51s with low intake show modest gains over eight weeks | 300mg with dinner, judged after eight weeks, expectations modest |
| Regularity | Constipation more common with age | A small morning citrate, 100mg to 200mg, alongside evening glycinate if wanted, under 400mg total |
| Medications | More prescriptions, more spacing questions; PPIs lower magnesium | The pharmacist check, every time |
| Kidneys | Function declines with age | No supplements without a clinician if kidney function is reduced |
The serving, and the safeguards that come with it
When food falls short, the serving does not change with the decade: Futuro Labs Magnesium Glycinate, 2 capsules with the evening meal, 300mg elemental at 80% NRV from bisglycinate at 20%, covering the 270mg target with margin and sitting under the 400mg guidance level, vegan, UK made under GMP and BRC, panels shown, £19.99 for 180 capsules, 22p a day. One capsule, 150mg, suits a diet that nearly covers it. The safeguards are the difference between this page and the younger version: the pharmacist spacing check across every current medicine, the kidney conversation where function is reduced, and a preference for the plain single-ingredient product precisely so those conversations stay short. How much magnesium per day for a woman over 50: 270mg, the same as always, met with more care than before.
What to check on the label
- 270mg a day from all sources: unchanged after 50 and after 60.
- Bone and muscle raise the stakes: magnesium supports both, alongside calcium, vitamin D, protein and loaded exercise.
- The sleep evidence was generated in this age group: modest, eight weeks, no claim.
- The pharmacist check becomes routine: levothyroxine, bisphosphonates, PPIs.
- Reduced kidney function: clinician first, before any supplement.

Questions people also ask
How much magnesium should a 60 year old woman take?
270mg a day from all sources, the same reference intake as at 50. A 300mg glycinate serving covers it on a narrow diet, after a pharmacist check of current medicines.
Does magnesium need go up after menopause?
The UK reference intake does not change. What rises is the importance of meeting it, for bone and muscle, and the care needed around medicines and kidneys.
Is magnesium good for women over 50 for sleep?
The small sleep trials were run in over-51s with poor sleep and low intake and found modest improvements over eight weeks. No claim is authorised; expectations should match.
Which magnesium is best for a woman over 50?
Plain bisglycinate at 300mg elemental with dinner, with a small morning citrate only if regularity is also wanted. Single ingredient keeps interaction checks simple.
What should a woman over 50 check before taking magnesium?
Every current medicine with a pharmacist for spacing, especially thyroid, bone and acid-suppressing drugs, and kidney function with a clinician if it is known to be reduced.
