Magnesium and potassium supplements deserve a section dedicated exclusively to them, also because these two elements often characterize the different formulations precisely because of their concomitant presence. This happens because both prove useful in the same measure and in the same districts of the organism, especially as regards the production of energy through and its availability throughout our body. They obviously have a specific role: potassium intervenes in neuromuscular function and also as a balancer of the concentration of body fluids. Magnesium is the feminine element par excellence because in addition to acting as a catalyst for many energy reactions, it becomes a decisive part of those typical metabolic cycles of the woman linked to the menstrual cycle for example or to the regulation of the humoral tone when influenced by particular hormonal changes, such as during the menopause period. Therefore, when energy is needed or when we need to recover the right amount of mineral salts lost through sweating and physical exertion, these two elements must always be present in our integration and it is for this reason that the supplements based on their formulation they are all grouped in this section.
