Mechanism

Electrolytes maintain critical physiological functions: Sodium (Na+) is the principal extracellular cation regulating plasma volume, blood pressure (via RAAS system), nerve impulse conduction (fast sodium channels), and glucose absorption (SGLT1 co-transporter). Potassium (K+) maintains resting membrane potential via Na+/K+-ATPase, essential for cardiac rhythmicity and muscle contraction. Magnesium (Mg2+) is required for ATP function (Mg-ATP), muscle relaxation (calcium antagonism), and >600 enzymatic reactions. Sweat contains ~40-60 mmol/L sodium, ~4-8 mmol/L potassium, and trace magnesium. Hyponatremia from excessive water intake without sodium replacement during prolonged exercise is potentially fatal.

Standard Dosing

Varies by activity level: 500-1500mg sodium, 200-400mg potassium, 100-200mg magnesium per liter of fluid during exercise

Timing

Before, during, and after exercise. Daily electrolyte support for low-carb/ketogenic diets (increased electrolyte excretion). First thing in morning for general hydration.

Cycle Duration

ongoing during training; increased during heat, prolonged exercise, or ketogenic diet

Side Effects

  • GI cramping (hyperosmolar solutions)
  • Bloating
  • Hypernatremia/hyperkalemia if excessive
  • Diarrhea (magnesium component)

Contraindications

  • Hyperkalemia with potassium component
  • Heart failure (sodium restriction may be required)
  • Renal failure (impaired electrolyte excretion)
