A December 2019 study by the Women's Health Initiative found that there was a reduced risk of heart disease related to higher magnesium intake.

The Virginia Commonwealth University Institute for Women's Health, said: "If the findings of this study are confirmed, future research should test whether high-risk women would benefit from magnesium supplementation to reduce their risk of fatal coronary heart disease."

Good sources of magnesium are whole grains, seeds, dry beans, low-fat dairy, nuts, and greens.
