Calcium is not energy 20

Calcium ions are key to muscle contraction and relaxation, and without calcium the heart strikes.

It is very helpful to human beings.

Calcium is the source of life of the human body, and it is the most abundant inorganic element in the human body, with a total amount of more than 1 kg, and has the reputation of "life element" of the human body.

Calcium 99 in the human body is deposited in bones and teeth, promoting their growth and development, maintaining their shape and hardness; l It is present in blood and soft tissue cells and plays a role in regulating physiological functions.

The physiological role of calcium ions determines its importance to human life activities:

Calcium is inherently important for blood clotting. When calcium is deficient, blood clotting disorders occur, and the human body will have symptoms such as bleeding gums, subcutaneous bleeding spots, irregular uterine bleeding, menorrhagia, blood in the urine, and hematemesis.

Calcium ions play an important role in the excitation of nerves and muscles and the conduction of nerve impulses. When calcium deficiency occurs, the body experiences symptoms such as nerve blockade and dystonia.

Calcium ions play an important role in cell adhesion and the maintenance of cell membrane function. The cell membrane is not only a barrier to the contents of the cell, but also a carrier for various essential nutrients and oxygen to enter the cell. Normal levels of calcium ions ensure that the cell membrane smoothly "pumps" nutrients into the cell.

Calcium ions have an activating effect on enzymatic reactions in the human body. As we all know, enzymes are the catalyst for the metabolic process of various substances in the human body, and it is an important life substance in the human body, and calcium deficiency will affect the normal physiological metabolic process.

Calcium ions play a decisive role in the secretion of human endocrine glandular hormones, and are essential for maintaining the functions of circulatory, respiratory, digestive, urinary, nervous, endocrine, reproductive and other system organs.

In short, calcium is an indispensable trace element for the human body, it is not only the constructor of the body, but also the regulator of the body, and the source of life of our human body.

In addition to being the basic raw material for bone development and directly affecting height, calcium also has other important physiological functions in the body. These functions play an important role in maintaining the health of the body and ensuring the smooth progress of normal growth and development. Calcium can promote the activity of certain enzymes in the body and regulate the activity of enzymes; Involved in the activity of nerves, muscles and the release of neurotransmitters; Regulates the secretion of hormones.

Calcium is also needed for blood clotting, cell adhesion, and muscle contraction. Calcium also regulates heart rhythm, reduces cardiovascular permeability, controls inflammation and edema, and maintains acid-base balance.

Nowadays, people's quality of life is slowly improving, and people are paying more and more attention to the absorption of nutrients in the body. It is often said that children who are deficient in calcium do not grow taller, and people who are deficient in calcium do not have particularly good bones compared to ordinary people. So, calcium is an important element of the human body, is it that the more calcium supplements, the more fearless?

The answer is definitely no. Everything in the world has two sides, and whether it is lacking or excessive, it will lead to a series of problems related to it, and only appropriate is the best.

Calcium is an indispensable and very rich mineral in the human body, it can be said that it participates in the entire life cycle process of the human body, from the formation of human bones at the beginning, to the contraction of human muscles, to the beating of the human heart, and then to the thinking activities of the human brain, and finally to the growth and development of the human body A series of processes are inseparable from calcium in the human body. But it's only a part of the elements that the human body needs, and it can't be said that the more you have, the more you have to be fearless.

At different stages of the human body, the amount of calcium required by different parts of the body is also very different. For children, 400 mg to 700 mg per day is best. For people in the adolescent stage, because adolescence is more active, the metabolism is particularly vigorous every day, and the demand for calcium is also more, and then about 1300 mg is included every day.

For adults, compared to the adolescent stage, but not so vigorous, infants have less calcium requirements, including about 800 mg to 1000 mg per day. Then in middle and old age, because middle-aged and elderly people are prone to osteoporosis and the loss of bone density is very fast, the demand for calcium in middle and old age is greater than that in the adult stage, and the included calcium is at least not less than 1000 mg. By the time we reach old age, the functions of all cells in the human body are declining.

In everything, we must remember a truth, it is appropriate to be appropriate, and things must be reversed.

In fact, there is no truth in this sentence, sometimes the body can not absorb too much calcium, which will also cause some adverse effects.

No. Calcium supplementation also needs to be moderate and should not be overdosed. Because if you take too much, calcium will accumulate in the kidneys, which can cause kidney stones.

First, calcium supplementation will cause constipation, increase the risk of urinary tract stones, and cause kidney damage in severe cases; Second, high calcium intake may also inhibit the effective absorption of iron, zinc and other essential minerals in the small intestine, causing a deficiency of corresponding minerals in the body; Third, if the intake of calcium is very high, it will cause hypercalcemia.
