Experts Link Magnesium Deficiency to Anxiety as Nearly 50% of Americans Fall Short
3 articles · Updated · GQ · Jul 11
Summary
Nearly half of Americans may be deficient in magnesium, a gap experts say can heighten anxiety by disrupting GABA regulation and raising cortisol, leaving the body more prone to fight-or-flight responses.
400 to 420 milligrams a day is the recommended intake, but specialists said taking more than that does not add extra anxiety protection.
Food should come first—beans, lentils, nuts, seeds, whole grains, leafy greens, fish and dark chocolate were highlighted as practical ways to raise magnesium intake.
Magnesium supplements may help people with confirmed deficiencies, with experts favoring magnesium glycinate over topical products and suggesting morning, night or split dosing based on symptoms.
The broader message is that magnesium is not a standalone cure for anxiety, but correcting a deficiency can support calmer mood, better sleep and improved stress resilience.
