What's inside
Five ingredients per bottle. Tap each one.
-
The carrier. Nothing more.
-
Our fiber, from oats. The entire reason this bottle exists — 10g per shot, most of your daily gap.
-
A single gram of fruit sugar to round out the lemon-lime. It is the only added sugar in the bottle.
-
A mineral salt that keeps acidity in check so the shot stays smooth, not sour.
-
Lemon and lime. That is the whole flavor story.
