Three Natural Electrolyte Drinks for Post-Workout Muscle Cramps
When you exercise, your body loses water and minerals through sweat.
Plain water replaces water but does not replace all of those minerals.
Losing too many minerals may contribute to muscle cramps for some people.
Coconut water is a natural source of potassium and also contains smaller amounts of magnesium and sodium.
Lemon water with a little salt provides sodium, but it does not contain all the minerals your body may need.
Buttermilk provides fluids, several electrolytes and protein.
Drinking amounts suited to the workout may help, especially after longer or hotter exercise.
Stretching, cooling down, eating electrolyte-rich foods and avoiding sudden increases in exercise intensity may also help.
Frequent or unexplained cramps, weakness, swelling or symptoms that continue despite hydration should be discussed with a doctor.
Plain water replaces fluids but not electrolytes such as potassium, sodium, magnesium, calcium and chloride.
Fresh coconut water provides potassium and smaller amounts of magnesium and sodium, and may help reduce post-exercise cramps.
Lemon water with a pinch of salt supplies sodium but may need other minerals for a more balanced recovery drink.
Buttermilk contains fluid, sodium, potassium, calcium and protein to support hydration and muscle recovery.
Recurrent cramps, excessive sweating, dizziness, fatigue or headaches after exercise may indicate a need to reassess hydration and electrolyte intake.
