Magnesium is known to contribute to 300 biochemical functions within the human body. One of the many processes it is notable for is the adept way it helps enzymes to convert food in to energy by extracting its nutrients. It keeps bones healthy by stimulating something called calcitonin which absorbs calcium from the blood before directing it to your bones. Magnesium is also found within joints and muscles and helps to prolong the onset of tiredness and fatigue. Not only is magnesium produced by the human body but it can also be found within many varieties of foods and plants including nuts like cashews and almonds and also spinach, wholemeal bread and quinoa. These tablets contain 110mg of magnesium.
