The science
Protected by design.
Our proprietary emulsion technology wraps the alkaloids in tiny protective droplets, built for better bioavailability.
The flavor
Real flavor, in harmony.
The same emulsion that protects each molecule also carries our flavor, so you taste bright, true fruit that works with kratom's natural earthiness instead of fighting it.

-
Wrapped
Each molecule is suspended inside a tiny droplet instead of floating loose in the water.
-
Protected
The droplet's shell shields the molecule from breaking down in the can, from the fill line to your last sip.
-
Bioavailable
The emulsion is formulated for better bioavailability.
The flavor

The same emulsion that protects each molecule also carries our flavor, so you taste bright, true fruit that works with kratom's natural earthiness instead of fighting it.
-
True, bright fruit
Flavor is emulsified into the same tiny droplets, so real fruit notes come through clean and crisp in every sip.
-
Melded, not masked
Instead of piling on sweetness to cover the leaf, the flavor blends with kratom's natural bitterness into one smooth, balanced taste.
-
Zero sugar needed
Nothing to hide means no sugar to hide it with. Just a crisp, refreshing seltzer, best served ice cold.
