Calcium in Human Body

Calcium is vital for the formation of strong bones and teeth and for the maintenance of healthy gums. It is also important in the maintenance of a regular heartbeat and in the transmission of nerve impulses.

Calcium lowers cholesterol levels and helps prevent cardiovascular disease. It is needed for muscular growth and contraction, for the prevention of muscle cramps. It may increase the rate of bone growth and bone mineral density in children.

This important mineral is also essential in blood clotting and helps prevent cancer. It may lower blood pressure and prevent bone loss associated with osteoporosis as well. Calcium provides energy and participates in the protein structuring of RNA and DNA. It is also involved in the activation of several enzymes, including lipase, which breaks down fats for utilization by the body.

In addition, calcium maintains proper cell membrane permeability, aids in neuromuscular activity, helps to keep the skin healthy, and protects against the development of preeclampsia during pregnancy, the number one cause of maternal death. If high blood pressure develops due to pregnancy, it can be reduced by calcium intake.

Calcium protects the bones and teeth from lead by inhibiting absorption of this toxic metal. If there is a calcium deficiency, lead can be absorbed by the body and deposited in the teeth and bones.

Calcium deficiency can lead to the following problems: arching joints, brittle nails, eczema, elevated blood cholesterol, heart palpitation, hypertension (high blood pressure), insomnia, muscle cramps, nervousness, numbness in the arms and/or legs, a pasty complexion, rheumatoid arthritis, rickets and tooth decay.

Deficiencies of calcium are also associated with cognitive impairment convulsions, depression, delusions and hyperactivity.
