Skratch Labs Exercise Hydration Mix is an all natural sports drink. It replaces both the fluid and electrolytes you lose in your sweat while providing just enough calories to help fuel your working muscles. Flavored with only real fruit and containing no artificial colors or preservatives, our drink mix won't upset your stomach, leave a bad taste in your mouth, or challenge your IQ with tongue twisting chem-lab ingredients. It just works better. Maybe that's why, for years, top athletes have been secretly replacing their sponsors' products with drink mix made from Skratch.
