Our Verdict
Klean Hydration is one of the few electrolyte products with genuine NSF Certified for Sport status (lot-by-lot testing for 290+ banned substances). The carbohydrate-inclusive formula is designed for fluid absorption during athletic activity, not zero-calorie daily use. However, the electrolyte amounts are surprisingly low for a sport product (180mg sodium, 70mg potassium), and at $2.00/serving the value proposition is weak compared to competitors.
