Magnesium is an essential supplement when it comes to maintaining optimal health. Not only is it vital to hundreds of enzyme reactions, but it has many health benefits attached to it. Magnesium is a shock-absorber and helps to prevent the body from experiencing excessive amounts of stress. It also helps in the absorption process of other key elements: calcium, phosphorus, sodium, and potassium. Magnesium is essential for growth, development, the healing of wounds, and the proper utilization of thiamine. It also aids in temperature regulation, which is key to adequate brain and nervous system functions. Excessive shaking, nervousness, muscle spasms and an irregular heartbeat can be helped just by taking a Magnesium supplement.
