Most Americans aren’t getting enough magnesium – and that’s a problem since individuals with intakes below the recommended daily allowance are 40 percent more likely to have elevated C-reactive protein (CRP) levels than people getting enough of this vital mineral. Researchers at the Medical University of South Carolina have found that CRP can trigger acute inflammation, which is a significant risk factor for heart disease. The good news is that this research also shows it doesn’t seem to matter if your magnesium comes from natural food sources like spinach, tuna, nuts, and seeds, or from supplements. If you do supplement, look for the glycinate form of the mineral to maximize absorption and minimize gastrointestinal issues.
