The authors show that use of biologically active additions to food Bio-Normalizer, Oxine, Gonsyn and Lovsin is effective method of immune correction of human functional state. These biologically active additions to food lead to increase 15-25 per cent of T-helper activity, activates 20-32 per cent of B-component of immune system, enhance of immunocompetent cells cooperation and rise human antibacterial resistance. That all optimizes immune response and increases resistance to extreme impacts.
