Does magnesium glycinate help with inflammation?

The evidence doesn't support magnesium glycinate, or any form of magnesium, as a way to lower inflammation. The largest meta-analysis on the question — 18 trials, 927 adults — found no significant effect on CRP, IL-6 or TNF-α, the standard blood markers of inflammation, at any dose or duration tested.

What the evidence doesn't support

It doesn't support magnesium glycinate as a treatment for inflammation, arthritis pain, gout, or rheumatoid arthritis. It doesn't support the idea that raising magnesium intake lowers inflammatory blood markers in a general adult population — the largest pooled analysis of that question came back null. And it doesn't establish that magnesium supplements do anything for gout specifically; the research linking magnesium to gout is observational, not a trial of supplementation.

What the trials found

A 2022 dose-response meta-analysis in Biological Trace Element Research pooled 18 randomized trials (927 adults) testing oral magnesium against CRP, IL-6 and TNF-α. None of the three markers moved by a statistically significant amount, and modeling magnesium's effect across different doses and treatment lengths found no dose-response relationship either — more magnesium, or longer use, didn't track with a bigger change. The trials varied in the form and amount of magnesium used; the review didn't isolate glycinate.

A narrower 2025 meta-analysis in Frontiers in Nutrition looked only at people with metabolic syndrome — a population with higher baseline inflammation — pooling 8 trials (444 participants) that ran at least 2 months. There, magnesium supplementation was associated with a small drop in CRP (standardized mean difference −0.33, a result right at the edge of statistical significance, p = 0.048), with the clearest effect at 12–16 weeks, in tablet or capsule form, and more pronounced in women than men. That's a specific population with a specific baseline, at doses and forms the abstract doesn't itemize — it isn't evidence that magnesium lowers inflammation in someone without metabolic syndrome, and a result this close to the statistical line is not a strong one.

On gout specifically, a 2024 analysis of NHANES data (18,039 US adults) found that a higher magnesium-deficiency score was associated with higher odds of having gout — people with the most depleted magnesium status had roughly double the odds of gout compared with those with none. But that's a cross-sectional association, not a supplementation trial, and the study explicitly found that dietary magnesium intake didn't change the relationship. No trial has tested whether taking a magnesium supplement changes uric acid levels, gout flares, or gout pain.

No trial in this search tested magnesium supplementation against rheumatoid arthritis or fibromyalgia symptoms as an inflammation outcome. That's an absence of research, not a negative result — it simply hasn't been studied that way.

Questions people ask

Does magnesium glycinate help with inflammation, or reduce it?

The largest meta-analysis on the question — the 18-trial pool above — found no significant effect of oral magnesium on CRP, IL-6 or TNF-α in adults generally. A smaller, more specific analysis in people with metabolic syndrome found a modest CRP reduction, but that's a narrower population and a weaker result than a general claim would need.

Is magnesium glycinate good for gout, or for arthritis pain?

There's no supplementation trial for either. The gout research that exists is observational — lower magnesium status tracks with higher gout risk in population data — which is a different, weaker kind of evidence than a trial showing that taking a supplement changes the outcome. No trial has tested magnesium glycinate, or any magnesium form, against arthritis pain.

Is magnesium glycinate good for fibromyalgia?

Not on inflammation grounds — no trial has tested that. Fibromyalgia is a separate topic from the inflammatory-marker research reviewed here, and this page doesn't cover it.

When to talk to a doctor

Persistent joint pain, gout flares, or a rheumatoid arthritis or fibromyalgia diagnosis are reasons to talk to a doctor about treatment, not reasons to expect a supplement to change an inflammation marker. Magnesium glycinate is not a treatment for gout, arthritis, or any inflammatory condition. If you take medication for any of these, or are pregnant or nursing, talk to a doctor before adding a supplement.
