Additional Information

In addition to building healthy bones, calcium plays essential roles in muscle contractions, heartbeat, blood clotting, nerve transmission, and in converting signals from hormones in the blood into actions within cells. Magnesium is involved in over 300 vital cellular processes, and helps to regulate the action of calcium in muscle function and heart health.
