Bottom line. Magnesium shows a Grade B benefit for inflammation — moderate-certainty evidence from randomised trials, especially in adults. Typical studied doses are varies across trials. [1 RCT]

Direction
benefit
Magnitude
Meta-analysis of RCTs: magnesium supplementation significantly reduced several inflammatory markers, most consistently serum C-reactive protein (and nitric oxide), versus control. The effect on downstream clinical outcomes is not established — this is a biomarker signal.

Frequently asked

How long does Magnesium take to work for inflammation?

Trials of Magnesium for inflammation typically report effects within 2–4 weeks, though individual response varies. Studies rarely find benefit inside 1 week for chronic outcomes.

What dose was used in studies of Magnesium for inflammation?

Studied doses for Magnesium in inflammation trials cluster around varies across trials. See the dose block for the specific range and how it varies by form.

Does Magnesium work for inflammation if I'm not deficient?

The effect concentrates in adults. If your baseline is normal, expect a smaller effect than the trial averages.

Magnesium or the next-best alternative for inflammation?

See the compare block above for the head-to-head with the most-cited alternative. Grade + certainty differences matter more than any single trial.
