Could a simple magnesium pill boost depression treatment?

This study looks at whether adding a magnesium supplement (magnesium bisglycinate) to standard antidepressant medication can help adults with major depression feel better. About 84 people aged 18-65 who are already on a stable antidepressant will receive either the supplement or a placebo for several weeks. Researchers will track changes in mood, anxiety, sleep, and daily function to see if magnesium offers extra relief.
