Clinical studies were conducted to evaluate the effectiveness of the developed dietary supplement, based on vegetable oil and maral antler extract, containing phospho- and glycolipids. The dietary supplement was prescribed to a group of 30 patients (main group) for 4 weeks, once before or during meals in the first half of the day, in a dosage of 10 drops. The control group of patients did not receive any dietary supplements. Based on screening diagnostics, all patients were found to have autonomic nervous system (ANS) disorders. The patients in the main group had an average of 10±2 clinical manifestations of panic attacks (PA). A reliable decrease in clinical manifestations of PA was observed in all patients taking the dietary supplement (p<0.05). A complete alleviation of manifestations such as fear of death and the feeling of inability to control oneself at any given time was observed. There was a subjective improvement in well-being, manifested by decreased emotional instability, increased vitality and performance, increased work effectiveness, and decreased complaints about PA in all patients. The additional inclusion of nutritional supplements in the diet of patients with PA resulted in a significant redistribution of adaptive response types towards a reliable increase in the number of patients with a physiological response of training and activation, and a reliable (p < 0.05) decrease in the number of patients with acute and chronic stress. Based on the studies, it was concluded that the additional inclusion of dietary supplements in the diet leads to reliable normalization of the functional state of the autonomic nervous system, increased overall performance, and adaptive responses. A positive dynamic was observed in the state of the central and autonomic nervous system. The mechanism of ANS harmonization involves a decrease in tone via the sympathetic nervous system, followed by normalization under the influence of the parasympathetic nervous system.
