Sweat Sodium Testing in Brenham
Brenham is home base. Individual sweat tests run year-round here, and you pick your own time slot.
Lab-grade testing with Precision Fuel & Hydration measures how much sodium you actually lose in sweat — a figure that varies roughly tenfold between athletes, which is why generic electrolyte advice so often misses. You leave with a hydration plan built around your own number.
