In addition, calcium assists in the process of blood clotting and helps prevent the accumulation of too much acid or too much alkali in the blood. It also plays a part in muscle growth, muscle contraction and nerve transmission. Calcium absorption is very inefficient.
Unabsorbed calcium is excreted.
