When choosing a sugar free electrolyte powder iHerb shoppers should focus on sodium, potassium, and magnesium content.

Staying hydrated isn’t just about drinking water. During workouts, heat exposure, or heavy sweating, the body loses electrolytes—mainly sodium, potassium, and magnesium. Many sports drinks replace these minerals, but they often come with added sugar that some people prefer to avoid.

That’s why sugar-free electrolyte powders have become popular—especially among gym-goers, keto followers, and anyone focused on clean daily hydration.
In this guide, we compare the best sugar-free electrolyte powders on iHerb, based on mineral content, ingredient quality, taste, and overall value.
