Calcium – chemical element, without which man cannot live. This is the most accurate from the point of view of biochemistry and physiology, a definition for this object. At the cellular level, calcium is involved in more than 150 different biochemical reactions. It is part of hydroxyapatite, the main mineral component of the bone matrix.
The unique physico-chemical properties of calcium provide the necessary margin of safety to the human skeleton, teeth and nails. Calcium is involved in conducting nerve impulses, provides the diastole of the myocardium (the resting phase of the heart muscle) and is one of the factors of blood coagulation. Therefore a deficiency of calcium can lead to catastrophic consequences. In the process of growth and development of the organism significantly increases the daily requirement for calcium. Especially important is “the implementation of this biological norm” at 100% for pregnant women, children and adolescents. During pregnancy and adolescence significantly increases the risk of callgathering States.
One of the most dangerous pathologies associated with calcium deficiency is osteoporosis. Disease of the skeletal system, which decreases the density of bone matrix and calcium “washed out” from the skeleton into the blood. The main clinical signs of osteoporosis are:
- protracted pains in the bones;
- the development of periodontal disease;
- fatigue, irritability, emotional instability;
- cramps in the legs;
- increased bone fragility (fractures);
- tachycardia and arrhythmia.
In the early stages, osteoporosis is often asymptomatic in nature and is the result of compensatory reactions of the organism to the overall calcium deficiency. Calciparine condition can occur due to stress and physical exhaustion. Sedentary lifestyle, lack of exercise, Smoking and alcohol abuse are risk factors for development of calcium deficiency in the body.
What foods are rich in calcium?
In addition to classic dairy products (milk, cheese, yogurt) as a source of natural calcium you can use celery, asparagus, parsley, broccoli, cabbage, beans and canned sardines or salmon. There are foods that reduce calcium absorption in the gastrointestinal tract and its bioavailability. This coffee, salt, spinach and sorrel.
How to choose an effective mineral complex to prevent deficiency of calcium?
When choosing a mineral complex, the consumer needs to be armed with the necessary information about the main active substances and forms of calcium. The recommendation of a physician and pharmacist will allow you to select the optimal product based on the individual characteristics of the patient. Today manufacturers include calcium in medications (tablets, capsules, ampoules, suspensions, solutions for drinking) in the form of various salts: phosphates, gluconates, carbonates, citrates, ascorbates, chlorides. Carbonate and calcium citrate are the main biologically active substances, which are found in vitamin-mineral complexes. The most recognized bio-available form of chelated calcium with amino acids. The chelates of calcium with aspartic acid by this indicator is significantly superior as carbonates, and salts of citric acid (citrates). For proper calcium absorption requires vitamin D3 (ergocalciferol) and magnesium. The ratio of calcium and magnesium mineral complex should be at the level of 2:1.
The daily requirement for calcium
The daily requirement for calcium for adults is from 800 to 1,200 mg. During pregnancy it is necessary to adjust the dosage of calcium based on the needs of the mother and the unborn child. Overdose of calcium can cause serious complications in the cardiovascular system. When choosing the dosage of calcium consider your daily menu foods that have a lot of this macronutrient (milk, cheese, etc.). Be careful when choosing mineral complex and take care of your health!
