Catalyte is NSF Certified for Sport®. Hydration and electrolyte balance are essential for all levels of exercise and athletic performance. Catalyte combines electrolytes with B vitamins, vitamin C, and D-ribose (which helps slow lactic acid build-up and stimulates energy recovery) for broad-spectrum repletion of nutrients and hydration of cells.* Catalyte is formulated with sodium in the ratio that is typically found in sweat. Its blend of potassium, calcium, magnesium, and zinc replaces the primary electrolytes lost in perspiration, while also helping to repair and rebuild muscle tissue.* To be mixed with water, it’s a tasty lemon-lime flavored electrolyte supplement low in calories with no artificial sweeteners. It’s perfect for before, during, and after a workout.
