Two powerful minerals. One simple, high-potency formula. Responsible for hundreds of biological functions in your body, calcium and magnesium are essential minerals with big potential health benefits. While your body uses 99% of its calcium for teeth and bones, 1% plays key roles in vascular contraction and vasodilation, muscle function, nerve transmission and more. Meanwhile magnesium is a cofactor in more than 300 biochemical reactions including healthy protein synthesis, blood glucose control, muscle and heart function as well as healthy mood and restful relaxation. Providing 1,000 mg of each, Solaray Cal-Mag 1:1 is formulated with calcium and magnesium that are chelated to citric acid for enhanced absorption and bioavailability. And because we're committed to crafting products that just work better, we've included a sun-grown, special base of herbs including parsley, watercress, alfalfa and dandelion for additional nutritive support to help you Live Brighter!
