You don’t just lose water.
Every mile, every climb, and every hour in the heat comes with sweat loss. And sweat doesn’t just take water with it.
It takes electrolytes — particularly sodium.
How much you lose depends on the athlete, environment, intensity, duration, acclimatization, and individual sweat composition.
Built around sodium.
Sodium
750mg
ROO SALT is intentionally sodium-forward because sodium losses can become substantial during prolonged endurance exercise, particularly as sweat volume increases.
250mg
Potassium
An essential electrolyte included alongside sodium.
60mg
Magnesium
Rounds out the electrolyte profile.
Built to work together.
ROO SALT wasn’t built in isolation. Its 750mg sodium profile was designed to work alongside ROO CARBS, which contributes an additional 250mg of sodium with 25g of carbohydrate per serving.
Together, one serving of each provides 1,000mg of total sodium plus 25g of carbohydrate — giving athletes a modular way to build hydration and fueling around the demands of the effort.

hydration.
Hydration isn’t one size fits all. Answer a few questions about your effort, conditions, and sweat profile to build a practical starting point.
