Why Higher Sodium and Magnesium Are Important for Hydration During Exercise
When you exercise intensely, your body loses both water and electrolytes through sweat. Sodium is the electrolyte lost in the largest amounts. Replacing sodium helps maintain normal fluid balance, nerve function, and muscle function during physical activity.
Sodium and Fluid Balance
Scientific studies have shown that drinks containing higher sodium concentrations help the body retain fluid more effectively after exercise compared to drinks with lower sodium content (PubMed 38004153). Maintaining sodium levels helps support normal muscle function and contributes to normal functioning of the nervous system.
Magnesium and Muscle Function
Magnesium contributes to normal muscle function, electrolyte balance, and reduction of tiredness and fatigue. Physical activity can increase magnesium losses through sweat, so active individuals may have a higher need to replace magnesium. Research shows that magnesium plays a role in supporting muscle function and normal energy-yielding metabolism during and after exercise (PubMed 17172008).
Citrate Salts for Absorption
In SUPPLME electrolytes, we use sodium and magnesium in citrate form. Citrate salts are easily absorbed and also help buffer the acid-base balance in the body, supporting overall performance in sports settings (PMC10781183).
Hydration Beyond Water
Hydration is not just about water. It is about replacing the electrolytes you lose in the right amounts to match your activity level. For those who train or compete regularly, a balanced combination of sodium and magnesium supports normal muscle function, maintains electrolyte balance, and helps reduce tiredness and fatigue.
