Magnesium

Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body, including insulin metabolism, blood sugar regulation, muscle relaxation, and sleep quality—all areas frequently disrupted in PCOS. Women with PCOS often have lower magnesium levels, and supplementation (typically 200-400 mg daily of magnesium glycinate or citrate) can improve insulin sensitivity, reduce anxiety and sleep problems, decrease inflammation, and support healthy blood pressure. As a well-tolerated supplement with minimal side effects, magnesium addresses multiple PCOS concerns simultaneously and is commonly recommended as a foundational part of a PCOS supplement regimen.
