Given the growing body of evidence pointing to the need for optimum magnesium nutrition in athletes, what tests are available to coaches for determining magnesium status? Muscle magnesium (obtained through a needle biopsy) is one of the most accurate methods of assessment, but it is time-consuming, very invasive and can cause discomfort.
