Sodium, potassium, magnesium and calcium are critical electrolytes which are all excreted in urine. Sodium and potassium help regulate fluid balance, muscle contractions and nerve signals. Magnesium supports the immune system and bone health, regulates heart beat and glucose levels, and helps create energy and proteins. Calcium helps build strong bones and teeth, and maintain healthy blood pressure.

Measuring urine electrolyte levels can help ensure you have enough of each to perform at your best.
