Not one EU country eats enough fiber. Here is what the research actually says.
An open research library built to answer the GLP-1 fiber question: what to take, how much, and when it actually helps. 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. Nausea and low energy hit hardest; constipation follows.
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 daily supplement, for Europe, for GLP-1 users, with the evidence shown openly.

01The 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.
Can You Take Fiber With a GLP-1? Timing, Safety, and Spacing
Yes, fiber is safe with Ozempic, Wegovy, and Mounjaro. The one timing rule that matters, why it is about your other pills not the injection, and when to take fiber.
Inulin vs Psyllium: How Two Fibers Differ (and When to Use Each)
Inulin ferments and feeds gut bacteria; psyllium gels and bulks stool. A precise, evidence-based comparison of how they work, what the research and EU regulators say, and how to choose.
The Best Fiber for Semaglutide (Ozempic, Wegovy): An Evidence-Based Guide
Constipation is the most common reason people on semaglutide (Ozempic, Wegovy, Rybelsus) add fiber. Which fiber actually helps, at what dose, and how to time it, based on the clinical evidence.
Which Countries Eat the Most Fiber? A World Cuisine Tour
Global fiber intake averages around 11g a day, but some traditional cuisines deliver far more. A region-by-region tour of the beans, grains, and dishes that pack the most fiber per plate, from Mexican frijoles to Ethiopian injera and Japanese sweet potato.
EFSA Fiber Health Claims: Which Are Real (and Why 9 of 10 Fail)
EFSA rejects roughly 9 of 10 health claims. What that means for fiber supplements: why chicory inulin holds the only authorized bowel-function claim, and how to read a label when comparing products.
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.
The daily fiber built for GLP-1 users, made in Europe.
We're developing a proprietary GLP-1 fiber formulation, taken once a day, specifically for the GLP-1 microbiome, dosing pattern, and regulatory environment of the EU and UK. Honest scope: we don't sell anything yet.
A daily habit you keep, through titration, the plateau, and the taper off.
Until we do, you get the library. Join now and the GLP-1 Fiber Cheat Sheet is yours today. The first run is 500 boxes. Everything we have learned publishing this site goes into it: a daily fiber built for GLP-1 users. Your email puts you in line for first pick, with 30% off for life.
