Can I drink just water?

Taking in the right amount of water will get you halfway to properly hydrating, but if that is all you do, then your performance will suffer and you could seriously injure yourself. The other half of the equation involves replenishing the electrolytes lost in sweat. Although sodium, potassium, calcium, and magnesium are all lost in sweat, sodium is, by far, lost in the greatest concentrations, with losses ranging from 200-700mg per 16 oz of sweat.

By choosing a hydration beverage that contains electrolytes at effective levels, you ensure you’re giving your body both the water and electrolytes it needs to perform optimally while preventing cramping and dehydration.
