Our Verdict
Skratch Labs is the gold standard for ingredient transparency in the electrolyte category: real fruit flavoring (actual lemon oil and lime juice, not 'natural flavors'), no fillers, no artificial anything, and clean mineral sources. The 19g sugar is intentional -- it's designed as a combined fuel + hydration product for endurance athletes, not a daily wellness supplement. For its intended purpose (exercise hydration), the formulation is excellent. For daily low-calorie hydration, look elsewhere.
