There are many trace elements in the human body, among which calcium is the most abundant one. It plays an important role in human health, metabolism and growth. Today, the Xiaobian of Constant Health will take you to know about calcium carbonate. Calcium is known to many people. But what about calcium carbonate? How much do you know?

What is calcium carbonate? Why choose calcium carbonate?

What is calcium carbonate?

Calcium carbonate is a kind of carbonate compound of carbon, an inorganic compound, and one of many calcium supplements.  But many people think that calcium carbonate is the first generation of calcium supplement products, and then its production is depreciated, in fact, this is not scientific. Experts from the China Health Association say that the main ingredient of calcium supplement products eaten by astronauts is calcium carbonate, which now occupies a large share of the market.

Why choose calcium carbonate for calcium supplement?

There are many calcium supplements on the market, such as calcium carbonate, calcium lactate, calcium citrate, active calcium, organic calcium, etc. Let's first understand these calcium preparations in detail.

Let's first talk about calcium ammonia phosphate, which is a kind of calcium supplement commonly used in Japan. The calcium content is relatively high, 23.3%. But this kind of calcium is difficult to absorb, and the phosphorus content is also high, which is harmful to kidney dysfunction.

Secondly, calcium lactate is one of the traditional calcium supplements in our country. It dissolves quickly, but its content is low. Calcium gluconate is one of these kinds of calcium. Its content is 9%. Adults need one kilogram of calcium daily, which is obviously low in calcium content and does not meet the needs of the population.

Calcium citrate has good water solubility and 21.1% calcium. It is also better for biological utilization than calcium phosphate. Its absorption does not depend on gastric acid. It is suitable for the elderly to take.

Active calcium is a mixture of calcium formed by calcination of biological calcium at high temperature. Its calcium content is high, but its aqueous solution is strong alkaline and irritating to the gastrointestinal tract. It is not suitable for the elderly with gastric acid deficiency. Eating with food can reduce gastrointestinal irritation.

Finally, calcium carbonate, which contains up to 40% calcium, has little side effects, relatively cheap price, high absorption rate, and can be similar to milk. It is a kind of calcium preparation which is easy to accept and widely used by the whole country. Calcium carbonate is listed in the national pharmacopoeia as the first calcium supplement recommended by the Chinese Society of Nutrition, and it is also a widely recognized calcium preparation in the world.

Because of many calcium preparations, people are dazzled when supplementing calcium. They don't know what to choose. Xiaobian tells us that there are three principles for selecting calcium: high calcium content, high bioavailability, high intestinal absorption and low heavy metal content. Calcium carbonate is the first calcium supplement preparation, but it conforms to the principle of people's selection of calcium.

But in fact, what we say about calcium supplementation is that the human body needs to supplement calcium. It is not the preparation itself, but the calcium element in the calcium preparations. Those so-called preparations are only the carriers of calcium. Choosing the preparation of calcium supplementation mainly depends on the calcium content. The calcium carbonate content is as high as 40%, which is the best among many calcium supplementation preparations.

Supplementary calcium carbonate can help to form a strong body and teeth, reduce bone loss, help the normal operation of the nervous system, calcium supplement, but also help women reduce pre-menstrual irritability and irritability. In addition, it can also help myocardial contraction and expansion, help regulate the heartbeat, play a role in protecting the heart.

Tips for Calcium Supplement: Don't follow the advertisement, have your own health concept and know what you want. In addition, calcium supplementation plus vitamin D supplementation is more conducive to calcium absorption. For those who need calcium supplement, it is better to choose the "Tihengjian" brand of calcium, which is rich in calcium carbonate. After fine treatment, the source of calcium is good, and vitamin D helps the body absorb calcium.
