Magnesium deficiency is one of the leading nutrient deficiencies in adults with an estimated 80 percent being deficient in this vital mineral. Magnesium is an essential dietary mineral, and the second most prevalent electrolyte in the human body. It is in every cell of the body and it is necessary from proper bodily function. It is involved in more than 600 reactions in the body. https://www.ncbi.nlm.nih.gov/pubmed/25540137
Approximately 60% of the magnesium in the body is found in bone. The rest is in muscles, soft tissues and fluids, including blood. https://www.ncbi.nlm.nih.gov/pubmed/25540137
One key function in which Magnesium plays a very important role is in muscle movements, more specifically related to the contraction and relaxation of muscles. Magnesium functions as a natural calcium blocker to help muscles relax.In both skeletal muscles, and in the heart, calcium binds to proteins such as troponin C and myosin. This process changes the shape of these proteins, which generates a contraction. Magnesium interacts with calcium enabling muscles to relax. https://www.ncbi.nlm.nih.gov/pubmed/7286246
Insufficient magnesium typically your cause muscles to contract excessively, causing cramps or spasms. Therefore, magnesium is commonly recommended to treat muscle cramps. https://www.ncbi.nlm.nih.gov/pubmed/8754704
A deficiency causes neural excitation, increases blood pressure and reduces glucose tolerance. Magnesium is vital for GABA function, an inhibitory neurotransmitter that produces serotonin. Certain hormones, including serotonin, regulated by magnesium are crucial for calming the brain and promoting relaxation, which is one reason why a magnesium deficiency can lead to sleeplessness or insomnia. Maintaining healthy magnesium levels is also associated with a protective effect against depression and ADHD. Initial scientific research into the effects of magnesium supplementation boosting physical performance is promising. Magnesium plays a critical role in brain function and mood, and low levels are linked to an increased risk of depression.
