Total calcium (Ca+, Calcium)

Calcium is one of the most important trace elements in living organisms. It performs many functions that affect the health and normal functioning of the body. Although calcium has a wide range of actions, its main function is to maintain the strength of bones and teeth.

First of all, calcium is an important building block for human bones and teeth. About 99% of the total calcium in the body is concentrated in the skeleton. It forms hydroxyapatite crystals, which give bones their strength and rigidity. Without enough calcium, bones become weak and brittle, which can lead to diseases such as osteoporosis.

In addition, calcium is an important regulator of many biochemical processes in the body. It participates in the transmission of nerve impulses, in particular in the constriction and dilation of blood vessels, controls muscle contractility, regulates blood clotting function and the activity of many enzymes.

Calcium is also an important component in the secretion of hormones and neurotransmitters. It affects the endocrine system, in particular the parathyroid glands, which produce parathyroid hormone. This hormone regulates the level of calcium in the blood by stimulating its release from the bones, which helps maintain optimal calcium levels in the body.

To ensure the normal functioning of the body, it is important to ensure that there is sufficient calcium in the diet. The main sources of calcium are dairy products (milk, cheese, yogurt), leafy greens (spinach, broccoli), and fish (especially sardines and salmon).

It is important to consider that calcium interacts with other trace elements, such as vitamin D and magnesium. Vitamin D promotes better absorption of calcium in the intestines, while magnesium supports its normal metabolism in the body.

Calcium deficiency can lead to a variety of problems, including osteoporosis, muscle cramps, nervous system disorders, and other diseases. On the other hand, taking in too much calcium can affect kidney function and create the conditions for kidney stones to form.

Therefore, calcium is an essential component of a healthy life. Following a balanced diet rich in calcium and other beneficial trace elements helps maintain healthy bones, cardiovascular system, nervous system and endocrine system.
