This question is about Running
Runners need magnesium because it is an important electrolyte that plays a role in cellular metabolism, protein synthesis, energy metabolism, muscle contraction, oxygen uptake, electrolyte balance, and hydration. A recent study found that marathon runners who consumed adequate amounts of unsaturated fat, iron, potassium, and magnesium had better race-day performance [ 1 3
1]. Additionally, research suggests that magnesium supplements may improve overall sleep quality, which is important for running performance [
Studies have shown that a deficiency in magnesium is associated with low level chronic inflammation, which can lead to a variety of issues for runners [ 2
