30-Day No-Questions-Asked Guarantee
Try it for thirty days. If it isn't the fiber routine you actually keep, send back what's left and we'll refund you. No forms, no interrogation.
How many gummies should I take?
+
Two a day. That's one serving — 5g of soluble fiber. You can take them together or split them across the day, with or without food.
Will these cause gas or bloating?
+
Adding fiber quickly can do that to anyone, regardless of the source. There's also 1g of sugar alcohol per serving. If you're sensitive, start with one gummy a day for three or four days, then move to two. Drink water alongside.
They're sugar free, so what makes them sweet?
+
Sucralose, plus 1g of sugar alcohol (sorbitol) per serving. No sugar is added, and there's no high fructose corn syrup.
Are these vegetarian or vegan?
+
No. These gummies are made with gelatin. They also contain tree nuts (coconut), and they're produced in a facility that handles egg, fish, shellfish, soy, and tree nuts.
Fast Shipping. Risk-Free Guarantee.

I've started so many fiber routines and quit by week two. This one I just... keep doing.

How The Habit Actually Sticks The Routine
Fiber works cumulatively. Here's how to build a routine that survives past week one.
Days 1–3
Start Simple
Start with two gummies a day, with or without food. If you're new to added fiber, one a day for the first few days is a gentler on-ramp.
Week 1
Build The Habit
Two a day, same time each day. Pair it with something you already do: coffee, brushing your teeth, so you don't have to remember it.
Week 2 And On
Stay The Course
Keep going. Fiber works cumulatively, not overnight. Give it a full bottle before you judge it.

I've tried three other fiber gummies that barely had any fiber in them. This one actually lists 5g on the label.

Two gummies after coffee and that's it. Way easier than mixing powder every morning.

Berry and peach actually taste good, so I don't dread taking them. That's the whole difference for me.

Two gummies, once a day, right next to my toothbrush. Haven't missed a day in a month.
