“Magnesium reduces anxiety”

Does magnesium reduce anxiety? What the evidence says

Amber
Mixed or weak evidence

The short answer

Possibly, for some people, but the evidence is weak. A systematic review found hints of a benefit in people prone to anxiety, including mild anxiety and premenstrual symptoms, but the studies were generally small and of poor quality.

Where the claim comes from

Magnesium is involved in the body's stress response and nervous system signalling, and low magnesium has been linked with anxiety in animal studies. Many people also don't get enough magnesium from their diet. That makes it a plausible idea, which is why it is so widely repeated.

The honest summary

Magnesium might take the edge off mild anxiety for some people, and it is generally safe at normal doses for healthy adults. But it is not a proven anxiety treatment. Leafy greens, nuts, seeds and wholegrains are good food sources. If anxiety is affecting your daily life, please speak to your GP, as there are treatments with much stronger evidence behind them.
