Product Review

Catalyte Isotonic is an electrolyte replacement formula that helps replenish vitamins and minerals lost through sweat. Although sweat rate and mineral concentration can vary, Catalyte Isotonic is formulated with the typical ratios of sodium found in sweat and a blend of potassium, calcium, and magnesium to support additional electrolytes lost during activity. We also add zinc, which is lost through sweat but rarely seen in electrolyte products, and D-ribose to help refuel muscles. Catalyte Isotonic contains no sugar or caffeine. It's designed to optimize hydration and can blend with other performance boosters like carbohydrates or Aminos. Catalyte Isotonic is lightly sweetened with a zero-calorie stevia extract and flavored with lemon-lime flavoring. Catalyte Isotonic is NSF Certified for Sport®.*
