Fascinating article in reputable journal arguing for mineral deficiencies as a way to understand and treat depression.
Might mean reconsidering supplementation studies.

Another article (of several) looking at psychiatric illness and micronutrients. Seems plausible, safe, and well tolerated. This study was with children.
Still I need to be clear that these results SHOULD NOT replace use of psychiatric medications. There is scant evidence they work alone.
