MAGNESIUM : contributes towards reducing tiredness and fatigue, electrolyte balance, normal energy metabolism, muscle function, normal protein synthesis, maintaining bones in normal conditions and intervenes in the process of cell division. POTASSIUM : plasma potassium levels tend to decrease during exercise (1). Potassium is essential for isotonicity, electrolyte balance, nerve transmission, and active transport mechanisms (2). ZINC : contributes to the proper functioning of various metabolic aspects such as DNA synthesis, acid-base metabolism, carbohydrate metabolism, macronutrient metabolism, fatty acid metabolism, vitamin A, protein synthesis, maintaining healthy bones under normal conditions, functioning of the immune system and the protection of cells against oxidative stress. VITAMIN B2: contributes to the maintenance of mucous membranes, maintenance of red blood cells, protection of cells against oxidative stress and reducing tiredness and fatigue. VITAMIN B3: contributes to normal energy metabolism, maintenance of the mucous membranes and reduce tiredness and fatigue. VITAMIN B5: contributes to normal energy metabolism, mental performance and reducing tiredness and fatigue. VITAMIN B6: contributes to the normal synthesis of cysteine, normal energy metabolism, normal metabolism of homocysteine, proteins and glycogen, maintenance of red blood cells, normal functioning of the immune system and reducing tiredness and fatigue. VITAMIN B12: contributes to the normal synthesis of amino acids, normal blood formation, normal homocysteine metabolism, normal functioning of the immune system, reduction of tiredness and fatigue and is involved in the process of cell division.
