Calcium is not found naturally in its elemental state and is found mostly in sedimentary rock in the minerals Dolomite, Calcite and Gypsum. Within the human body, Calcium is one of the most important elements because it makes up the structural component of our bones, teeth and soft tissues and is necessary for our metabolic processes as well as simple muscular contraction. Calcium makes up about 1-2% of our body weight. Calcium is a big part of us and this world.
