GOOD TO KNOW

Frequently asked
questions

How is this fiber ranking put together?
Every candidate is scored from public NIH label data on dose adequacy, form, third-party verification, label transparency, and price per effective dose, plus a GLP-1-specific check that favors soluble-first fiber sources (psyllium, PHGG) over insoluble-bulk-first formulas. We earn nothing on any pick. How scoring works: /glp-1-supplements/methodology/.
What happens to a fiber product's score when no independent seal exists?
It loses the verification points — the score says so honestly instead of pretending verification exists. Third-party certification is rare among the fiber products we score, so the ranking leans on what can still be verified: the label's own disclosed dose, form, and transparency, and price per effective dose.
Should I add a fiber supplement while taking Ozempic?
That's not a call this site makes. Constipation-type complaints are commonly discussed by people on GLP-1 medications, but whether a fiber supplement is right for you — and how to introduce one — is a conversation for your prescriber or pharmacist. What we publish is a like-for-like comparison for people who have already had that conversation.
