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
Calcium deficiency disorders manifested in the construction of the bones (osteoporosis) and iron metabolism. The symptoms are: rickets, cramps and muscle tremor, osteoporosis.
Excess result
ing 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)



Serrapeptase is a proteolytic enzyme (breaking down protein) obtained from the digestive system of silkworms – moths, specifically its larvae. It can be formed in the fermentation process owing to enterobacteria Serratia sp. E-15.

For silkworms, this enzyme is significant to dissolve their hard cocoon and promotes the digestion of indigestible mulberry leaves. For humans, serrapeptase may have in turn a positive impact on bodily functions, in particular cardiovascular function.

It is absorbed directly through the intestines into the bloodstream. It is suggested that the enzyme may break down, among others, clots, fybrosis and atherosclerotic plaque owing to its ability to “dissolve” dead tissues. Consequently, it may have a special supporting role in arterial embolism and atherosclerosis. A similar mechanism of action is observed in external protective layers of cancer cells – by dissolving them, it may promote anti-cancer processes.

This enzyme is characterised by anti-inflammatory properties and that is why it can bring relief, e.g. from pain caused by rheumatoid arthritis or carpal tunnel syndrome.



Nattokinase — an enzyme derived from fermented soya owing to the activity of Bacillus subtilis, used mainly due to its cardioprotective properties. It prevents the formation of blood clots and is thus a crucial preventive measure against cardiovascular disorders that are one of the most frequent causes of death.

Apart from its antiplatelet properties, nattokinase promotes a healthy cardiovascular system due to its ability to optimise blood pressure. Some sources say that this enzyme has a beneficial effect on the elasticity of blood vessels. It can be therefore acknowledged that this agent optimises blood flow through veins and arteries

Nattokinase is indicated to have a beneficial impact on the human body. This is because it improves the transport of blood (along with nutrients) to peripheral tissues .
