Calcium (element chem. symbol Ca, atomic no. 20, the group of alkaline earth metals) is the basic building substance of bones and teeth, in which stored is 99% of the element, in the form of hydroxylapatite. When building bones and teeth, phosphorus is very important in the right proportion. It is a base-forming element and activator of many enzymes (ATPase) necessary to release the energy of ATP. It has a significant effect on blood clotting and regulates blood pressure and neuromuscular conductivity. Thanks to the reduced permeability of cell membranes, it soothes the symptoms of food allergies. Calcium is actively involved in the metabolism of iron interacts with vitamins A, C and D and phosphorus, magnesium. Natural source of calcium are animal products (dairy products, sardines, salmon, sprats eaten with bones) and plant products (nuts, soybeans, sunflower seeds). Absorption takes place in the small intestine (less in the colon), it has an effect on the level of lactose, insoluble fibre, organic acids, alkalinity (low pH). The best absorption have organic compounds (lactates, amino acid chelates etc.). Obstructing the absorption of calcium is caused by: phytic acid and oxalic acid as well as excess fat. Scientific studies have confirmed that the combination of calcium, magnesium, boron and vitamin D in dose 3 mg / 24h effectively prevent osteoporosis. Supplements on the market are both mono-preparation supplements (enriched with vitamin D3) and multi-component supplements, available at www.muscle-zone.pl.
Calcium deficiency disorders manifested in the construction of the bones (osteoporosis) and iron metabolism. The symptoms are: rickets, cramps and muscle tremor, osteoporosis.
Excess resulting from an overdose of calcium supplements containing vitamin D3 for children and adults overdose of calcium (hypercalcemia). Symptoms of hypercalcemia are: lack of appetite, vomiting and constipation.
The dosage administered in various publications are inconsistent: 800 - 1000 mg / 24 h (100 - 500 mg / 24h)
Calcium carbonate – a salt of carbonic acid and calcium, used in dietary supplements as one of the calcium forms, because of its high bioavailability. It is an alkaline salt, which is why it is used for neutralisation of the environment in the stomach.
Calcium is a macroelement necessary for the proper functioning of the body system. It is a building material of teeth and bones as well as it determines their mechanical strength. The proper supply of calcium prevents osteoporosis in elderly people and allows for the proper development of skeletal system in children. It is an activator of many enzymes, is involved in the inflammatory processes and regulates secretion of particular hormones. It is also essential for muscle contraction and determines blood coagulation. Moreover, calcium ions allow for transmission of nerve impulses by synapses, so that they regulate the proper neural transmission.
The demand for calcium increases with training intensity, which is why it is recommended for athletes to increase calcium supply. Calcium deficiency can be caused by high-protein diet.
DHEA (dehydroepiandrosterone) is the base product for the production of the hormones, estrogen, progesterone and testosterone, which are produced by the adrenal cortex, having androgenic action and anabolic effects. It works on the nervous system, reducing feeling of stress. It speeds up the metabolism by limiting the formation of adipose tissue. It has an impact on the insulin metabolism. Rarely used in sports supplementation, it is used in supporting sports condition for men aged 40+.
Dosage: Up to a few hundred mg per day, depending on individual needs.
