After 30 Years of Clumpy Fiber, I Built Something Better

The fiber supplement I always wished existed.

THE PROBLEM

I've been taking fiber supplements for 30 years.
I tried them all. Metamucil. Benefiber. Citrucel. Every store brand. The capsules, gummies, wafers—everything.

Here's what I learned: Fiber drinks work. Everything else is a waste of money.

But even the best fiber drinks had the same problems:
They clumped if you didn't stir aggressively.
They tasted artificial. Orange flavor that barely passed as "orange."
They spiked blood sugar. I tested this with a continuous glucose monitor.
They felt like punishment. Not something you look forward to.

After three decades of dealing with this every morning, I decided to fix it.

THE SOLUTION

I'm Matthew. I spent 30+ years in consumer sales and marketing at P&G, Johnson & Johnson, and Method Products. I know how to build products people want to use.

And I know what makes great fiber—because I've been taking it daily since my 20s.

ForBelly is the fiber I always wished existed:

→ High-mesh psyllium that mixes smooth without aggressive stirring 

→ Natural lemon-ginger flavor that tastes refreshing, not medicinal 

→ Gentle fizz from sodium bicarbonate (makes it feel like a treat) 

→ No blood sugar spike unlike sugar-based formulas 

→ Perfect for weight loss - keeps you full, regular, and comfortable

Great mix. No drama. Just results

Cheers,
Matthew Brenner

WHY WE NEED TO TALK ABOUT POOP

Here's the thing: gut health shouldn't feel embarrassing or clinical.

Regular, comfortable, perfect poos are the foundation of feeling good. They affect your energy, your mood, your confidence, your entire day.

Great poops equal great days. That's not marketing talk. That's real life.

For too long, fiber has been treated like something you choke down in private and never mention. That's ridiculous.

ForBelly is built to destigmatize fiber and make it something you actually look forward to—not just tolerate.

WHO IT'S FOR

ForBelly is for anyone tired of fiber that clumps, tastes like medicine, or doesn't actually work.

It's especially great if you're:

→ On a weight loss journey (fiber keeps you full between meals) 

→ Taking GLP-1 medications like Ozempic or Wegovy (helps with regularity and satiety) 

→ Looking for something that actually tastes good 

→ Building a morning routine you can stick with

If you've been avoiding fiber because it's gross, or putting up with fiber that barely works—this is for you.
