The Science

Hydration is a science.
We treat it like one.

Every milligram in our formula has a peer-reviewed reason to be there. Discover the science behind performance hydration done right.

Isotonic Formula

285 mOsm/kg

Matched to blood plasma osmolality for maximum absorption speed. Faster than any sugar drink.

Lab Verified

Third-Party Tested

Independent sports nutrition lab confirms 340% faster cellular hydration vs. leading sugar drinks.

Zero Sugar

No Compromise

Zero added sugar, zero artificial colors, zero dyes. Nine real-science compounds, nothing fake.

Absorption Science

Why osmolality matters

Your body absorbs fluids through osmosis — water moves from low concentration to high concentration across cell membranes. When a drink's osmolality is higher than your blood plasma, your body actually has to work to absorb it, slowing hydration.

At 285 mOsm/kg, BaselineH₂O is isotonic — perfectly matched to blood plasma. This means zero osmotic resistance, maximum absorption velocity, and genuine cellular hydration rather than just moving fluid around.
