Why Magnesium is important to our body? Magnesium is a FUEL for our busy body. It is needed for aerobic (= with oxygen) and anaerobic (= without oxygen) energy production. Magnesium fuels over 600 processes in the body. Magnesium supports many physiological processes, including ACTIVE ONES like muscle contraction and more CALMING ONES like relaxation and sleep.nesiu Magnesium supports a healthy heart, skeletal system and inflammatory response, as well as steady blood pressure, blood sugar and energy levels.m f Possible Symptoms of Sub-Optimal Magnesium Intake Muscle cramps, twitches or tremors  Regular or excessive fatigue  Feelings of irritability and/or lethargy  Frequent mood swings, including depression  Pre-menstrual bloating  Restless legs at night  There are three main organs that stored high magnesium, which are brain, bone and muscle. How does Magnesium work in the brain? Activates Serotonin to induce satisfaction and regulate attention. Activates GABA to improve mood and sleep. Reduces Cortisol to reduce stress and excitation. Magnesium In The Bones Magnesium is required for the production and release of parathyroid hormone. The parathyroid hormone produced by the thyroid glands helps maintain the right balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning. This is especially important for nerve and muscle function, as well as bone health. Magnesium converts vitamin D into its active form so that it can help calcium absorption. Magnesium - the unknown nutrient for muscle and strength Much of the body’s energy comes from ATP, a molecule that captures chemical energy from food and uses it to fuel other processes in the body.
