Calcium: properties and benefits

Sharing is caring!

Calcium is an essential mineral for building and maintaining bones and teeth. It is also very important for the muscle contraction and transmission of nerve impulses.

Being widely used by the body, it is essential that it is taken in sufficient quantity, especially during childhood. In fact, at this stage of life functions of calcium they are fundamental for the formation of the skeletal structure.

Functions of calcium and its benefits

the calcium is the mineral more present in our body and is essential for the functioning of the body.

It is estimated that 1% to 2% of an adult’s body weight is formed from this mineral. In addition, 99% of the body’s calcium is found in bones and teeth.

Below we present to you functions of calcium:

1. Why do we need calcium

Why-we-need-calcium

We need calcium from birth to old age.

In our childhood, it is necessary for the growth of human body bones and the teeth. During adolescence, bones are growing, so calcium is again essential to support growth.

Finally, as we age, the skeletal structure tends to become porous and weak, thus requiring a large supply of this mineral.

With so many crazy diets popping up every day, we often tend to steer clear of foods high in mineral calcium as whole food groups, including dairy products. Instead, we should never be without it.

But what is calcium for?

A sufficient supply of calcium for bones it is essential to strengthen the spine and ensure the good shape of the body.

It also helps prevent a number of ailments such as back pain, arthritis and osteoporosis. In addition to being very painful, these conditions can interfere with freedom of movement.

When a muscle is stimulated by the nervous system, part of it is released blood calcium. This substance supports the action of proteins during the phase of contraction of muscles.

Once the calcium is “pushed out”, the muscle relaxes.

Adequate amount of calcium it can help the heart muscles contract and relax properly. Calcium also helps the nervous system maintain adequate pressure in the arteries.

If there is one calcium deficiencya hormone called calcitriol is released, which constricts smooth muscle in the arteries, thereby increasing blood pressure.

Heart muscles need extra calcium ions to contract. As the intracellular calcium concentration increases, calcium ions collect in the troponin protein.

The secretion of extracellular fluids and intracellular reserves, including that of skeletal muscle, are thus stimulated, which are activated by the calcium stored in the bone tissue.

In addition to its main functions, calcium performs a number of other important tasks for our body. Specifically:

  • helps metabolize iron
  • promotes the blood clotting
  • stimulates the release of neurotransmitters and various hormones
  • keeps blood pressure balanced
  • promotes vasodilation and contraction of blood vessels
  • keeps cholesterol levels under control
  • contributes to healthy teeth and gums

  • over 50: 1200 mg per day

Let’s not forget that the absorption of calcium is favored by another precious substance for our organism, the Vitamin D.

4. Calcium deficiency

In addition to calcium deficiency symptomsInsufficient intake of this mineral carries several health risks. The most obvious is osteoporosis (decalcification of the bones) which can cause bone fractures.

When you don’t get enough calcium from the diet, your body will use the supply of this mineral from your bones, for example for blood clotting.

This means that getting enough calcium every day is extremely important.

5. Calcium supplements

The elemental calcium content of the most popular products is as follows:

  • calcium carbonate: 40%
  • calcium citrate: 21%
  • calcium lactate: 13%
  • calcium gluconate: 9%

6. Risks of supplements

Taking calcium through supplements is not without risk. Too much calcium in the blood it can indeed have a number of contraindications. Let’s take a brief look at them together.
