Calcium is the mineral present in greatest quantity in our organism, approximately 1.8% of the total weight. 99% of calcium is found in bones and dentin, which is the substance of which teeth are made. Bones don't just contain calcium, they also play a very important storage role. Calcium is mainly present in bones (98%), very little in teeth (1%) and in body fluids (1%). The main function of calcium in our body is linked to the construction of bones and teeth, where it plays a structural role in the musculoskeletal system, but it is also an important source of reserve, to maintain concentration. physiological plasma and meet certain metabolic needs.
Calcium regulates muscle contraction, is involved in the transmission of nerve impulses while maintaining a healthy nervous system. Calcium then normalizes blood circulation and regulates the heart rate, it keeps blood pressure and cholesterol low, and it also helps blood to clot. Calcium is also involved in the permeability of the cell membrane, in the multiplication and differentiation of cells, in the synthesis of several hormones and in the activation of certain enzymes. A truly multivalent role, even if it is strictly associated with bone formation.
The daily need for calcium varies from individual to individual, depending on age, gender and physiological conditions. In adults, 800 mg, in children (up to 10 years), between 400 and 500 mg, in adolescents, between 1000 and 1300 mg, in the elderly, 1000 mg, in pregnant and lactating women between 1,200 and 1,500 mg. Calcium is fundamental, together with synergistic vitamin D, for the constitution of the skeletal system from the first months of fetal development, which is why the needs increase during pregnancy and lactation. Then, after the peak of skeletal maturity (between 20 and 30 years), the density of calcium in the bones begins to gradually decrease. If calcium is lacking during the first years of life, the problems mainly relate to the bone structure, which has a reduced mineral density, with a risk of bone deformity and rickets. If the diet does not contain an adequate supply of calcium, the conditions vary from simple muscle cramps (even in the abdominal area) to tingling in the fingers, headaches and memory loss, irritability and loss of memory. nervousness. It can even go as far as dry skin, brittle nails, and hair loss. To, finally, move on to real dysfunctions of the osteoarticular system, such as bone pain, fragility and risk of fractures, dental caries, bone decalcification in the elderly and osteoporosis in postmenopausal women. Excess calcium is eliminated through body fluids: feces, urine and sweat.
The people who must control the integration of calcium are:
- those who do not take dairy products (because they are allergic or for other reasons);
- postmenopausal women, who are prone to osteopenia or osteoporosis;
- pregnant and lactating women;
- people over 55-60 years old;
- people with celiac disease or other gastrointestinal problems that can cause poor absorption;
- people on prolonged treatment with corticosteroids.
Since childhood, calcium, along with the parallel and complementary help of vitamin D, have been fundamental nutrients widely recommended by the medical class for the prevention and treatment of osteopenia, osteoporosis and fragility fractures. . Numerous studies have shown that poor introduction or internal production of these elements, or reduced absorption from the intestines, is linked to an increased risk of fractures in the elderly.
In addition, calcium and vitamin D are essential for the effective treatment of osteoporosis.
