Catalyte replaces what you lose through sweat with a clinically dosed blend of sodium, potassium, magnesium, calcium, and chloride, plus B-vitamins, vitamin C, and taurine to support energy metabolism alongside hydration. Developed by Thorne, a brand trusted by practitioners and professional sports teams, it's third-party tested and NSF Certified for Sport. With 485mg of sodium per scoop, it's built for real sweat loss, so if you're on a sodium-restricted diet, check with your doctor before daily use.
