Calcium and magnesium are two minerals that play critical roles in our overall health. Calcium provides structure to bones, is necessary for the optimal functioning of your muscles (especially your heart), nerves, and blood vessels. Magnesium is needed for important processes such as blood sugar regulation and muscle contraction.

Magnesium and calcium are found in a variety of foods, but factors like dietary intake, medication use, and health conditions can interfere with the levels of magnesium and calcium you have. This is why some people require supplements to complement their diets.
