Magnesium is a mineral that plays a very important role in the body. Adults who consume less than the recommended amount of magnesium are more likely to have elevated inflammation markers, which in turn has been associated with major health problems.
Calcium is a mineral that is an essential part of bones and teeth and the heart, nerves, and blood-clotting systems need calcium to work. The bones and teeth contain over 99% of the calcium in the human body. Calcium is also found in the blood, muscles, and other tissue. Calcium in the bones can be used as a reserve that can be released into the body as needed. The concentration of calcium in the body tends to decline as we age because it is released from the body through sweat, skin cells, and waste. In addition, as women age, absorption of calcium tends to decline due to reduced estrogen levels. Calcium absorption can vary depending on race, gender, and age.
