A pulsating magnetic field or PEMF is said to produce one main result: stimulating cell metabolism. This action is thought to cause a chain of processes in the body that could lead to improvement of health without side effects. A cell produces its energy, called ATP (Adenosine Triphosphate). This energy is necessary for the function of the body, building up and breaking down molecules, and transporting substances across cell membranes. To produce energy a cell needs oxygen and about 90 other substances including enzymes, glucose, and nutrients. In addition to energy, cells also produce carbon dioxide, water, and waste products. To be able to execute and control all these processes properly, good cell metabolism is required. Therefore, the cell needs a membrane potential of 70 Ð 90 mV (millivolt). Whenever this electrical potential drops, active metabolism is impaired. Low-performance levels and chronic disease are the results. Ultimately, every illness is the consequence of impaired cell metabolism.
