You started a GLP-1 medication.
Then came the constipation.

GLP-1 medications slow gastric emptying. That's how they reduce appetite. But it also slows your gut. You eat less food, which means less fiber, less water, less of what your body needs to stay regular. The result: constipation, bloating, a disrupted microbiome.

The standard advice is "eat more fiber." But high-fiber foods like beans and lentils are exactly the ones that worsen GLP-1 side effects. And most fiber supplements deliver 3-6 grams per serving, well below the 12 grams per day where research shows meaningful results.

We obsess over functional fiber for metabolic health.

The Good Fiber Company is an independent European fiber research and product company based in Berlin. We're building the fiber resource that should already exist but doesn't.

Every article goes through the same question: would this help someone make a better decision about their own health?

A fiber supplement is in development. In the meantime, we publish research, review what's available, and tell you what we'd actually recommend to a friend.

We're not selling you a miracle. We're closing a gap.

Europe has a fiber problem. GLP-1 users have it worst. We're building the product and the research to fix it. Join the waitlist for early access and product updates.
