Low-sugar, not sugar-free in every formulation—check the current label
Read the official product page →Sugar-free is useful when…
- • You want electrolytes without carbohydrate calories.
- • You prefer to manage workout fuel separately.
- • Convenience matters more than an all-in-one sports drink.
Sugar-free is not always better
Carbohydrate can be useful fuel during prolonged exercise. A sugar-free mix also may contain non-sugar sweeteners, and “zero sugar” says nothing about whether its sodium amount fits your needs.
