Tag: Magnesium loss

The concentration of magnesium in sweat is reported to average around 36 mg per liter, although this figure can fluctuate widely depending on individual factors and exercise intensity. Understanding precisely how much magnesium do you lose in sweat is important for athletes and active individuals to maintain peak performance and avoid health issues related to mineral depletion.

Research suggests that athletes may experience up to a 20% loss of magnesium during training or competition, putting them at greater risk for deficiency. So, do you lose magnesium through exercise, and what does this mean for your athletic performance and recovery?

A systematic review found that despite a higher dietary magnesium intake, athletes have a significantly lower serum magnesium concentration and higher urinary excretion compared to sedentary individuals. This indicates that intense exercise, and not just diet, plays a major role in determining how much magnesium do you lose when exercising.

The kidneys play a central role in regulating the body's magnesium levels, typically excreting about 120 mg of magnesium into the urine each day in healthy adults. This daily magnesium loss is part of a complex process of mineral homeostasis, but it can be significantly impacted by dietary intake, lifestyle, and medical conditions.
