everything you need

nothing you don't

Scientifically Optimal

The exact ratio of electrolytes your body needs to hydrate fastest. WHO-developed. Nothing extra.

OPEN-SOURCE HYDRATION

Our recipe is public, our math is public, and our mission is public. Because truth doesn’t need flavoring.

Radical Simplicity

Four ingredients. One proven ratio. Ratio cuts through the noise and delivers only what you need and nothing you don't.

Hydration is more than salt

Why it matters

Hydration isn’t just salt. Water uptake depends on sodium–glucose cotransport — requiring sodium, glucose, potassium, and citrate in precise balance.

Salt-only mixes like LMNT skip the mechanism. Ratio delivers the proven formula that drives actual absorption.

With Ratio, every gram is functional. Nothing is wasted.
