Yamamoto Research Magnesax is a dietary supplement containing magnesium, useful in cases of reduced intake or increased need for this nutrient. Magnesium contributes to electrolyte balance and normal muscle function. In addition, magnesium helps reduce tiredness and fatigue, supports normal energy metabolism and the proper functioning of the nervous system.Magnesium is one of the most important minerals for the body, it being the cofactor for a range of enzymes involved in many metabolic processes. In fact, magnesium is needed in many biochemical functions that ensure our body works efficiently. Indeed, magnesium plays a role in muscle contraction, in the normal functioning of the nervous system, in cardiac function and in the digestive system, combating states of fatigue and irritability, impacting upon the maintenance of hydrosaline balance and in the production of cellular energy.It is claimed that the majority of the population has a magnesium deficiency, for a number of reasons ranging from an improper and unbalanced diet due to eating fewer and fewer fruits and vegetables and an increased amount of processed foods such as dairy products, flours and sugars that do not contain magnesium and indeed, extract it from the body during the digestive process. The soil in which produce is grown has become greatly magnesium depleted due to intensive cultivation and the use of pesticides, thus rendering fruits and vegetables much poorer in this precious mineral.Those who use diuretics and laxatives may be lacking in magnesium, just like athletes may have a deficiency as a result of intense electrolyte depletion due to sweating. It is also common for the elderly to be lacking in magnesium. Magnesium glycinate is a form of magnesium in which the mineral is linked to an organic compound (a glycine molecule), allowing the mineral to have an increased absorption capacity in the intestine and therefore creating greater bioavailability, with less probability of favouring unpleasant diarrheal phenomena, thus being a form of magnesium that can be safely consumed to reverse long-term deficiency.
