It is the most common mineral in the human body. Calcium not only plays an important role in the formation of inert tissue, but also forms part of the blood, cellular and tissue fluids. This trace element directly affects the processes of muscle contraction, and, consequently, the whole physical activity of a person depends on it. It also affects the stimulation of the functions of a number of enzymes and hormones involved in the regulation of lipid metabolism. Its role is in the metabolic transformation of fats. Its high content in the body accelerates their "digestion" of cells and prevents them from accumulating in adipose tissue. Calcium in the body takes the form of hydroxyapatite salt, in the form of which is stored in the teeth and bones.
The most popular biological supplements contain calcium in the form of citrate or carbonate salt. In addition, some manufacturers add calcium in the form of malic acid salts to juices and other products.
Calcium is usually released from the complexes in the digestive tract to form a liquid form that is absorbed in the small intestine.
Although calcium is found in many foods, providing them with an organism is not an easy task, as it belongs to difficult-to-digest elements. For example, even an excess of saturated fat prevents calcium from being absorbed in the intestines.
The best natural sources of this trace element are milk and dairy products - milk, cottage cheese, yogurt, kefir.
Remember the charming rogue Panikovsky from the novel by I. Ilf and E. Petrov “The Golden Calf”, who loved kefir very much and taught his “companion” Balaganov: “Shura, drink kefir. It is very healthy. ” This statement of Mikhail Samuelevich was recently confirmed by American scientists.
It turned out that an increased amount of calcium suppresses calcitriol production, which makes any diet more effective. It is known that a decrease in calcitriol production increases the intensity of fat utilization and reduces the level of lipogenesis.
German nutritionist Dr. Zemel recommends that you do not strongly break away from your zoological roots. He found that a lack of calcium in the body contributes to an increase in the level of specific hormones, which in turn provoke weight gain. At the same time supplements containing calcium, the problem is not solved. To normalize the metabolism, the body needs only natural calcium, which comes from dairy products. Scientists have concluded that calcium contained in fermented milk products, the most effective compared with all other types of calcium. They recommend replacing part of the food kefir, and cottage cheese to stimulate the process of losing weight.
A prominent expert in the field of nutrition Dr. Harris from the University of Georgia Georgia also confirms this data. He suggests the feasibility of more detailed studies of the effect of fermented milk products on people suffering from obesity. So far, such studies are only being conducted, but many nutritionists of the world are already recommending to their patients daily intake of fermented milk products.
A chicken egg shell, made up of 90% calcium carbonate, is the easiest way to solve this problem. Calcium carbonate is easily absorbed by the body.

Calcium function is necessary for the structural integrity and mineralization of bones and teeth and plays an important role in a number of metabolic and regulatory processes. It is a concomitant factor of many enzymes necessary for the functioning of the nervous and muscular systems, a component of the blood coagulation system and a regulator of many intracellular processes. Adequate calcium intake is vital.
- Plasma calcium concentration
Normally, the concentration of calcium in the plasma is 8.5-10.5 mg / 100 ml (2.1-2.6 mmol / l). Approximately 50% of plasma calcium is in the free ionized form, 40% is associated with proteins (mostly with albumin) and 10% with anions (with citrate and amino acids). Physiologically active is free ionized calcium, the concentration of which ([Ca2 +]) is most pronounced in
- Calcium metabolism is normal
Normal daily intake of calcium is 600-800 mg. Absorption occurs mainly in the proximal small intestine. Calcium secretion is also carried out in the intestine, the rate of which is constant and does not depend on absorption. Usually up to 80% of the consumed calcium is excreted in the feces. Calcium is excreted through the kidneys, averaging 100 mg / day, and can vary from
- Calcium imbalance
Calcium plays a primary role in the metabolic and many physiological processes of the human body. It is the main component of the bones. Calcium ions play an important role in the transmission of intracellular signals, various enzyme reactions, blood coagulation. Calcium determines neuromuscular conduction. Regulation of stabilization of calcium balance is a process of great importance. 99%
- Calcium metabolism disorders
Calcium is found mainly in bones (98%), but maintaining its normal extracellular concentration is extremely important. Calcium ions are involved in almost all physiological processes, including muscle contraction, the release of neurotransmitters and hormones, blood clotting and bone tissue metabolism. Consequently, disorders of calcium metabolism can lead to severe disorders of many
- CALCIUM PHOSPHATE CRYSTALLINE
It was found that when calcium phosphate is precipitated from a highly saturated aqueous solution at a pH of more than 7, amorphous phosphates first appear. An amorphous precipitate can slowly transform into a stable crystalline precipitate due to the process of dissolution, renucleation and crystal growth. The rate of transformation depends on the pH. The stability of amorphous phosphates is improved at high pH.
- CALCIUM OXALATE CRYSTALLINE
Features Calcium oxalate dehydrate crystals are usually colorless, with a characteristic octohedral or oval shape (Figure 4-11). Under a light microscope they look like big or small squares, the corners of which are connected by diagonal lines. Calcium oxalate crystals are found in acidic, neutral or alkaline urine. Calcium oxalate crystals of monohydrate vary in size and can
- CALCIUM CARBONATE CRYSTALLINE
Calcium carbonate can crystallize in the urine of horses, rabbits, goats, forming large yellow-brown or colorless spheroids with radial striation, or small round, oval or dumbbell-shaped crystals (Fig. 2 and 3). In dogs and cats, these crystals are usually not detected. If a dumbbell-shaped crystal is found in the urine, then it is more likely calcium oxalate monohydrate. Fig.

- Regulation of extracellular concentration of ionized calcium
Calcium intake into the extracellular fluid occurs either during absorption from the intestine, or as a result of resorption from bone tissue; no more than 0.5-1% of bone calcium is involved in metabolism with extracellular fluid. Calcium can leave extracellular space due to: 1) deposition in bones; 2) urinary excretion; 3) secretion in the digestive tract and 4) excretion with sweat. Extracellular concentration
- Calcium deficiency in a child
Sometimes with breast milk, a child lacks calcium, even with a sufficient amount of it in the mother’s diet, due to a violation of calcium metabolism in her body. Calcium deficiency and disorder, in turn, calcium metabolism in a baby is fraught with disturbances in the development of the bone system and teeth, often accompanied by anemia, susceptibility to colds, infections and allergic reactions.
