Athletes lose significantly more electrolytes through sweat than the average person — up to 2000mg of sodium per hour of intense exercise. Standard sports drinks fall short, loading you with sugar while delivering minimal electrolytes. We tested 5 athlete-grade supplements on actual training sessions to measure electrolyte delivery, absorption speed, taste during exertion, and value per serving.
We tested each product for 30 days, measuring mixability, taste, electrolyte content accuracy, and real-world hydration effectiveness. Below you'll find our honest assessment to help you make the right choice for your specific needs and budget.
