Europe doesn't get enough fiber. We're fixing that.
An open research library on dietary fiber, GLP-1 medications, and what actually works. Built for the millions of Europeans on Ozempic, Wegovy, and Mounjaro who can't find a straight answer.
The fiber gap is the largest unaddressed nutrition deficit in Europe. Not one country meets EFSA's 25 g/day recommendation. Average intake is 18 g.
GLP-1 medications make this gap worse. Appetite drops; food volume drops; fiber drops with it. Constipation follows in up to 24% of users.
The supplement aisle hasn't kept up. Most products are American formulations sold to a continent with different food, different microbiome, different regulation.
So we're building a fiber resource — and eventually a supplement — for Europe, for GLP-1 users, with the evidence shown openly.

01What Is Dietary Fiber? Everything You Need to Know
What dietary fiber actually is, why most Europeans don't get enough, which types matter, and what the science says about dosing. A complete, evidence-based guide.
The European Fiber Gap: Why Almost No One in Europe Gets Enough Fiber
EFSA recommends 25g of fiber per day. No European country meets it. Here's what the data actually says, and why it matters more than ever for GLP-1 medication users.
How Much Fiber Do You Actually Need? (EU vs. US Guidelines)
EFSA says 25g. Germany says 30g. The US says 25-38g. Here is what the fiber recommendations actually mean, how they differ, and what most Europeans are really eating.
The Best High-Fiber Foods: A Guide by Regional European Diet
Europe's traditional diets are full of high-fiber foods most people have forgotten. Legumes, whole grains, fermented vegetables, and regional staples, organized by dietary tradition: Mediterranean, Nordic, Central European, and Atlantic.
GLP-1 Side Effects: What 410,000 Reddit Posts Reveal About Real-World Experience
A peer-reviewed study analyzed 410,198 Reddit posts from GLP-1 users. Constipation ranked #4, fiber confusion is everywhere, and clinical trials are missing the full picture.
Soluble vs. Insoluble Fiber: Which Type Do You Actually Need?
Soluble fiber dissolves, ferments, and feeds gut bacteria. Insoluble fiber adds bulk and speeds transit. Here is what each type actually does, which foods contain them, and how to choose the right supplement.
Everything we publish, open and sourced.
No paywalls. No marketing fluff. Every claim links to its source. The numbers below are the live state of fiber in Europe — pulled from EFSA, national surveys, and peer-reviewed studies.
A fiber supplement built for GLP-1 users, made in Europe.
We're developing a proprietary fiber formulation specifically for the GLP-1 microbiome, dosing pattern, and regulatory environment of the EU and UK. Honest scope: we don't sell anything yet.
Until we do, you get the library. When we ship, waitlist members get first access and first-batch pricing.
