What type of magnesium is good for inflammation?
No magnesium is anti-inflammatory; no claim is authorised. Trials show modest falls in C-reactive protein with supplementation, mainly in people started with raised levels and low magnesium. Glycinate, 300mg elemental, is the form; training inflammation is repair, not the enemy.

What the inflammation research actually shows
Two strands. Observational first: King's 2005 analysis of US dietary data found adults with low magnesium intakes were more likely to have elevated C-reactive protein, the standard blood marker of low-grade inflammation. Then trials: Simental-Mendia's 2017 meta-analysis pooled the randomised studies of magnesium supplementation and found a modest reduction in CRP, concentrated in people who started with raised CRP, and the wider literature ties the effect to people whose magnesium was low. Read together, the honest sentence is: a low magnesium intake is associated with low-grade inflammation, and correcting a low intake modestly lowers the marker in people who had both. No trial shows an anti-inflammatory effect in healthy people with normal intakes, and no inflammation claim is authorised for any magnesium in the UK.
Training inflammation is not the target
The soreness and swelling after a hard session is acute inflammation doing its job: it is the clean-up and rebuild signal, and blunting it on purpose is how you blunt adaptation, which is the argument against routine ice baths and pre-training painkillers. The inflammation the CRP research is about is the chronic, low-grade kind that tracks with poor diet, excess body fat, bad sleep and inactivity. A lifter chasing an anti-inflammatory supplement is usually solving the wrong problem; the levers on chronic inflammation are body fat, sleep, alcohol, fish and plants in the diet, and training itself, which lowers resting inflammation over months.
| Type | Elemental magnesium | Inflammation evidence specific to the form | Verdict |
|---|---|---|---|
| Glycinate (bisglycinate) | about 14% to 20% | None form-specific; the CRP trials used various salts | The form to hold at 300mg daily |
| Citrate | about 16% | None form-specific | Fine in the morning; laxative at a full dose |
| Malate, taurate, threonate | about 8% to 15% | None | No reason to pay more |
| Oxide | about 60%, about 4% absorbed | Used in some trials at high doses | Mostly unabsorbed; skip |
| Anti-inflammatory blends with turmeric or omega-3 | varies | Each ingredient has its own evidence and doses | Judge each ingredient on its own label; blends hide both |
Which type to take, and with what expectation
Glycinate, 300mg elemental, with the evening meal, because the CRP effect where it exists comes from correcting intake, and glycinate is the form a full dose can be held on. The worked example, Futuro Labs Magnesium Glycinate, gives 300mg elemental from 1500mg chelated bisglycinate in 2 capsules, 80% NRV, from a vegan capsule made in the UK under GMP and BRC certification and third-party tested for heavy metals and microbiology, 180 capsules for £19.99, 22p a day. The expectation to hold: normal muscle function, electrolyte balance and less tiredness where intake was low, per the authorised claims, and a modest CRP effect only if you were the person the trials describe. Joint pain, persistent swelling or an inflammatory condition are GP territory, and a supplement page is not where they get solved.
What to check on the label
- No anti-inflammatory, joint or immune claims on any magnesium label; none are authorised.
- Elemental magnesium 300mg per serving, 80% NRV printed.
- Glycinate first; the form does not change the inflammation evidence.
- Skip blends that bundle magnesium with turmeric or fish oil at unprinted doses.
- A GP for joint pain, persistent swelling or a suspected inflammatory condition.

Questions people also ask
Does magnesium reduce inflammation?
Trials show a modest fall in C-reactive protein mainly in people with raised CRP and low magnesium. No effect is shown in healthy people with normal intakes, and no claim is authorised.
Which magnesium is best for joint inflammation?
None treats joints; no claim is authorised. Persistent joint pain or swelling is a GP matter. Glycinate at 300mg elemental covers the intake side.
Is magnesium glycinate anti-inflammatory?
The form is irrelevant; the trials used various salts. The effect, where seen, comes from correcting a low intake.
Should I take magnesium after training to reduce inflammation?
Training inflammation is the repair signal and not something to blunt. Take magnesium daily for intake, not as a post-session anti-inflammatory.
What actually lowers chronic inflammation?
Losing excess body fat, sleeping, less alcohol, fish and plants in the diet, and consistent training. Supplements sit behind all of those.
