Electrolyte loss varies widely between athletes, ranging from roughly 200–2,000 mg of sodium per liter of sweat — so your fluid and electrolyte replacement needs are unique to you.

Sweat Sodium Testing in Austin
Victorem travels to Austin for scheduled group testing days. Each athlete is tested individually — the day is shared, the results are yours alone.
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.
