Calcium, Magnesium, and Zinc from Food Lowers Mortality
Getting enough magnesium and zinc from food is linked to lower mortality. Getting high-dose calcium from a supplement is linked to increased cancer death risk. That single contrast sits at the center of what research tells us about these three minerals: the source and the balance matter as much as, or more than, the raw amount. Calcium, magnesium, and zinc are essential for bone health, metabolism, nerve and muscle function, and immunity. Most people think about them individually, popping a calcium pill here or a zinc lozenge there. But these minerals share absorption pathways, compete with each other for entry into your body, and function in ratios. Getting one wrong can throw off the others.
