The fiber gap
You're probably missing this.
Most of us fall well short of the 25–38 g we need each day. One stick closes part of the gap.

Fiber works through consistency. A stick in the drink you already have every morning is the easiest way to stay on track.

-
Week 1
Ease in.
A stick every other day while your body gets used to more fiber.
-
Weeks 2–4

Keep going on autopilot, or get a full refund on your first order.
