Calcium, the most abundant mineral in the human body, has several important functions. More than 99% of total body calcium is stored in the bones and teeth where it functions to support their structure.

The remaining 1% is found throughout the body in blood, muscle, and the fluid between cells. Calcium is needed for muscle contraction, blood vessel contraction and expansion, the secretion of hormones and enzymes, and sending messages through the nervous system. A constant level of calcium is maintained in body fluid and tissues so that these vital body processes function efficiently.

 Benefits

The main function of calcium is in the structural development and maintenance of healthy bones and teeth.

Calcium helps to keep a check on the blood pressure and also it aids in muscle contraction, thereby enabling the heart and blood vessels to perform their functioning effectively.

Calcium is important for children and young people whose bones are growing rapidly. It also plays a crucial role in the transformation of light to electrical impulses in the retina.

Where is it found?

The best source of calcium is dairy products such as milk, yogurt and cheese. Other foods can provide calcium, too, such as dark green vegetables, dried beans and calcium fortified juices and cereals. Recommended Daily Intake: The most common supplemental amount for adults is 800 to 1,000 mg per day.

High levels of calcium in the body have been associated with a lower risk of cardiovascular disease in postmenopausal women, lower cholesterol levels and a decrease in the symptoms of premenstrual syndrome.

Calcium deficiency , usually the result of a metabolic problem rather than a dietary deficiency, causes numbness, tingling, and painful muscle aches and spasms.
