Gammadyn Mg acts on the central nervous system, the musculo-skeletal system and the endocrine system. Magnesium is essential for normal bone formation, calcium metabolism, controlling membrane permeability, muscular contraction, nerve impulse conduction, blood viscosity, activation of enzyme systems, intracellular fluid regulation, protein synthesis and hormone regulation. This oligo-element is indicated for conditions such as osteo-articular and muscular disorders, muscle cramps, water retention, digestive disorders, hypercholesterolemia, hypertension and premenstrual syndrome.
