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.
How long does shipping take?
+
Free shipping on every order, always — no minimum. [CLAIM — PENDING SUBSTANTIATION: insert actual dispatch and delivery windows once the fulfilment partner is confirmed.]
What if they're not for me?
+
Thirty days, no questions asked. Send back what's left and we'll refund you.

I've bought the powder three times and thrown it out three times. This is the first one I've finished the bottle of.

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.

Customer Reviews
Real people, keeping a fiber habit for the first time.
Actually Finished The Bottle
I've started so many fiber routines and quit by week two. This one I just... keep doing.
No More Powder In The Cabinet
Two gummies after coffee and that's it. Way easier than mixing powder every morning.
Tastes Like Candy, Not Medicine
Berry and peach actually taste good, so I don't dread taking them. That's the whole difference for me.
Simple Habit That Stuck
Two gummies, once a day, right next to my toothbrush. Haven't missed a day in a month.
