Currently, there is a growing interest to biological supplements created from the green freshwater algae of chlorella. Material and methods. The study involved 30 clinically healthy individuals between the ages of 17 and 66, 10 men and 20 women. The subjects used an aqueous suspension of live chlorella strain Chlorella Vulgaris IGF No. C-111 at a concentration of 19-34 million cells / ml. The course of admission was 28 days. Before and after the completion of the course, the following studies were conducted: anthropometry, studies of the composition of the body, studies of physical performance (test PWC170), general blood analysis, biochemical analysis of blood. Results and discussion. All subjects had a positive trend in subjective well-being, due to an increase in overall tone, a decrease in the duration needed to restore sleep, and normalization of bowel function. In the study of the dynamics of anthropometric indicators, no significant change in the weight of the subjects was revealed. However, a significant decrease in the waist and hip volumes was recorded. Unreliable changes in fat and muscle components were detected, and a tendency to decrease the amount of visceral fat was registered. Significantly increased indicator PWC170 / kg fat mass. A significant decrease in the values of systolic and diastolic pressure in the state of muscular dormancy was recorded. The values of the indicators of the double product and the Robinson index after the course significantly decreased, which indicates an improvement in hemodynamics during exercise. During a blood test, an increase in the number of leukocytes and lymphocytes (within normative parameters) was also registered, which let us assume the stimulation of the immune system of the blood on the first line of protection. When studying the functional state of the liver, indirect signs of an improvement in its detoxification function were found, and at the same time, there were no significant changes in lipid metabolism. Conclusion. At the previous dynamics of anthropometric indicators, there are no reliable signs of success. However, significant changes in performance and hips parameter have been registered. At the same time, when the compositional warehouse was not registered, there were no reliable reserves of fat and meat storage facilities. Tendencies to lower of visceral fat are registered. It the same times was shown an increase in the indicator PWC170/kg of fat mass, which is the more accurate parameter for determining the value of physical performance, just lower of weight and a ratio of PWC170/kg of total mass. Blood tests revealed no significant changes on the part of the red link, but a significant increase in the number of leukocytes and lymphocytes (within the normative parameters) was registered, which suggests that the immune system is stimulated by the first line of protection. A decrease AST/ALT ratio was observed which indicated an improvement in detoxification function of liver. At the same time, we did not register significant changes in terms of lipid metabolism, which were reported by some authors. This can be explained by differences in the concentration and state of aggregation of the active substance used in the studies: dry chlorella extract or, in our case, an aqueous suspension.
