Frequently Asked Questions
How much sodium do I need to prevent heat cramps?
Needs vary with sweat rate and climate, but many cramp-prone athletes benefit from mixes that provide several hundred to 1000 mg of sodium per litre. Start with a moderate concentration, monitor cramps and thirst, and increase sodium for heavy sweat losses or persistent cramping.
Should I use a carb-containing mix or a sugar-free electrolyte powder?
Use carb-containing mixes for sessions longer than ~60–90 minutes or when you need steady energy; choose sugar-free mineral powders for short workouts, keto diets, or if you want electrolytes without calories. For long endurance events, combining both approaches can also work (e.g., carbs during activity, tablets/dilute mix afterward).
Can these mixes reduce muscle cramps completely?
Electrolyte mixes help reduce cramps caused by sodium and mineral losses, but cramps have multiple causes (muscle fatigue, conditioning, biomechanics). Use appropriate electrolyte intake, stay well trained, and address pacing and muscle conditioning alongside hydration strategy.
