How much sodium do you actually lose?
If plain water covers you, we'll say so.
Sweat carries sodium out with it. Six quick taps estimate your loss per hour — and which tier fits.
01
Volume
Session length, sport, environment, how soaked your kit gets.
02
Saltiness
White salt marks, stinging eyes — the signals your body already gives you.
03
Your dose
Volume × saltiness gives your range, and a recommendation: water, 500, 1000, or a mix.
