Calcium: benefits and daily rate for the person

Not everyone knows that calcium is good not only for teeth and bones. Its spectrum of action on the human body is quite extensive. Take a look at what other processes are affected by this element.

1. Calcium is involved in blood clotting. To be precise, it prevents the formation of blood clots that clog blood vessels and is often fatal.

2. The process of contraction of muscles and excitability of nerve tissue is also dependent on the amount of calcium in the body. If not, you can start cramps and spasms in the muscles, periodically tingling in the extremities.

3. The amount of calcium in the body depends on the adrenal glands, pancreas and thyroid gland, reproductive system. Even in a healthy person the work of the organs of these systems can be broken if there is not enough calcium in the body or, on the contrary, there is a surplus.

4. Received by the body calcium is consumed also in liquid tissues and cells (the nucleus and the cell membrane also including calcium).

It should also be noted that calcium by itself is not so useful than in tandem with some elements. For example, have the same benefits for teeth and bones would be the same calcium is not do. The bones become stronger due to simultaneous use of calcium and phosphorus.

Normal operation of the cardiovascular system depends to a large degree on the amount of magnesium in the body. But calcium significantly enhances the positive effects of magnesium.

Best absorption of calcium is dependent on vitamin D levels in the body. If enough, calcium will be easier to enter the cells.

• children to 6 years – 1500 mg;

• 7 to 9 years – 700 mg;

• 10 to 12 years 900 mg (boys) and 1200 g (girls);

• from 13 to 20 years – 1200 mg;
