SUMMARY
Selenium and chromium are essential microelements, which deficiency in food products conditions their decrease in the organism that results in the development of metabolic processes disorders. The use of biologically active additives of different generation allows to replenish the microelements reserve more or less. Properties of biologically active additives of organic nature have an advantage over their inorganic compounds and cause more therapeutic effect at disturbed metabolism. Biologically active additives of water plants are of a great interest. Preparations of Chlorella vulgaris, that is not only a source of biologically accessible chlorophyll, series of amino acids and so on, but also fatty acids that have antitoxic or antisclerotic effects recommended themselves rather well. There were elucidated the results of the studies that allow to note the positive influence of selenium-chromium-lipid complex of Chlorella vulgaris on metabolic processes in rats with experimental diabetes mellitus type 2. The skillful use of food additives for attaining the balance of food rations may cause regulation of prophylactic and treating measures, but any their use without scientific substantiation can cause negative results
