About · The Good Fiber Company

Europe is under-fibered.
We’re fixing that.

GFC is the European authority on dietary fiber for metabolic health. We publish research, we cite our sources, and we’re building a fiber product that actually works for people taking GLP-1 medications.

01 · The problem

Not a single European country meets its own fiber guideline.

The European Food Safety Authority recommends at least 25 grams of dietary fiber per day. Germany’s DGE says 30. The British Nutrition Foundation says 30.

Average intake across the continent sits between 16 and 24 grams. Every country, every age bracket, every diet survey we’ve looked at: the gap is real and the gap is consistent1.

Adult intake, EU-27 mean
19.7g/day

Roughly five grams below the EFSA floor. In Spain, eight grams below.

02 · The compound problem

For Europeans on GLP-1s, the gap doesn’t add. It multiplies.

Semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro) reduce appetite. That’s the point. But less food means less fiber, and the high-fiber foods that would help are often the ones that make side effects worse.

STEP 01

GLP-1 starts

Appetite drops. Energy intake falls 20–35% in the first 12 weeks.

STEP 02

Fiber follows

Less food means proportionally less fiber. The 19g average becomes 13–14g.

STEP 03

Side effects appear

Constipation, bloating, slow transit. Affecting 30–40% of users.

STEP 04

High-fiber foods get cut

Whole grains, legumes, raw vegetables. The exact foods that would help.

And the loop closes
Our mission

We build the best fiber knowledge and products in Europe, starting with the people who feel the gap most.

03 · How we work

Three values. Each one is a contract with the reader.

01

Empathy

We start from what you’re actually going through, not from what’s easy to sell. Every article and every product decision begins with the real GLP-1 experience: the nausea, the not-feeling-like-yourself, the one more thing to manage. We write for the person living it, we credit your intelligence, and we never make you feel like a patient. No jargon, no hype, no talking down.
02

Substance

Every claim cites a source. Every statistic references a study. We’d rather say less and be right than say more and be vague. We cite primary sources only, and the full whitelist sits below. If the evidence isn’t there, we say so on the page.
03

Foresight

We share what we’ve found before it’s obvious. We connect dots others haven’t. The GLP-1 fiber gap is the example: it was sitting in the literature for two years before anyone in nutrition press wrote about it.
04 · What we cite

We don’t cite influencer blogs, supplement-brand whitepapers, or wellness magazines. If a finding only lives in a press release, it doesn’t reach our pages.

05 · Why we exist

A wave of demand is forming. Europe has no brand built for it.

GLP-1 medications are reaching millions of people across Europe, and the fiber gap they open keeps widening. The demand for a serious answer is arriving faster than the market can respond.

But Europe is not one market. Diets, regulations, languages, and shelf habits differ from Copenhagen to Madrid, and the supplement brands built for the United States do not translate. No one is building a fiber brand designed for this continent, in its own languages, to its own standards.

That is the work. We research first, in four languages, then build a product to the same standard. We started with the library because trust has to be earned before anything is sold.

Independent, by design

The Good Fiber Company is an independent research company based in Berlin. The work, the sources, and the standard are the point.

Some articles in our library link to products on Amazon, and we may earn a small commission. We keep those links for a reason that matters more than the cents: what readers actually buy tells us which fibers to research next. It is market signal, not a business model.
