The purpose of the study was to conceptualize a system of views on the role of internal electromagnetic fields in the human body to understand the essence of the course of metabolism, the phenomena of biological life and health. Materials and methods. General scientific methods (dismemberment and integration of elements of the studied system, imaginary experiment, logical, historical research, analysis, induction, deduction, and synthesis of knowledge) and theoretical methods (method of constructing theory, logical methods, and rules of normative nature) were used in this theoretical study. Results and discussion. The informative and analytical presentation of the magneto-electrochemical theory of metabolism, life and health is published in the article in the form of the main postulates and conclusions of the atomic and molecular levels of the structure of living biological systems, including humans. This is the first attempt by scientists to combine existing fundamental knowledge about the role of electromagnetic processes in the human body from the standpoint of Systemic Medicine. 12 postulates and 4 conclusions regarding the atomic level and 26 postulates and 6 conclusions regarding the molecular level of the structure of living biological systems, including humans, are presented. All materials are available for viewing in the monograph “Magneto-electrochemical theory of metabolism. Conceptualization”. Conclusion. The life of a biological system is a process of magneto-electric activation of its biomolecules, which starts and ensures their biochemical activity and determines structural integrity in their collective interaction of a single organism. Modern deepening of fundamental knowledge to the level of the course of magneto-electric processes at the molecular level in living biological systems is expedient to be fully integrated into medical science with a change of the electrochemical paradigm of metabolism to a magneto-electrochemical one. Knowledge and understanding of the quantum-mechanical features of the functioning of biopolymers in living systems, the understanding of the essence of their energy functioning, the organization of the form and role of electromagnetic components is the next step to deepening the fundamental knowledge of the pathogenesis of diseases of internal organs with a further approach to optimizing their treatment and prevention
