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.
