Case studies of magnesium supplementation reported improvements in depression, anxiety, and sleep within 1 week.
Concerning anxiety, sleep issues, and depression, case studies that explored magnesium supplementation for these issues reported improvements in all three within one week of starting supplementation.
Supplementing with 248–305 mg of magnesium per day has been shown to improve mood in people with depression and low magnesium levels.

Medical research has linked magnesium to reduced anxiety. Magnesium helps you to relax by stimulating the production of melatonin and serotonin which boost your mood and help you sleep. Magnesium also reduces the production of cytokines and cortisol, which lead to increased inflammation and stress.
Notably, magnesium reduces epinephrine and nor- epinephrine synthesis and release, decreases anxiety and could prevent the panic attacks. Magnesium deficiency, even when mild, increases susceptibility to various types of neurologic and psychological stressors in healthy human subjects and diverse groups of patients.
Having low magnesium levels may negatively affect brain health. Supplementing with magnesium may help reduce certain symptoms of brain fog.
