A transparent ranking of creatine products, with the limits of direct GLP-1 evidence stated plainly.
Why creatine matters for GLP-1 users
Once creatine stores are saturated, the sports-science consensus is that a 3–5 g daily maintenance dose sustains them — the same reference range we score every product against.
Creatine monohydrate is the most extensively studied and clinically effective form of creatine — "fancier" forms don't score higher here, since the evidence doesn't support a performance edge, but they usually cost more.

OUR METHOD
How we ranked this
We score every creatine product the same way: how well-dosed it is against a clinical reference amount, whether the form is a good one, whether an independent lab has verified what's on the label, how clearly the label discloses every ingredient, and price per effective dose. On top of that, we add one GLP-1-specific check — for creatine, that means checking the form is monohydrate — the best-studied form — rather than a pricier, unproven variant. Every score is public and reproducible from the same two data sources anyone can check.

GOOD TO KNOW
Frequently asked questions
Should I take creatine on Ozempic to prevent muscle loss?
There are no direct creatine × GLP-1 clinical trials — our evidence here is general-population and mechanistic (the Barbell Medicine standard), not GLP-1-specific. We say so plainly on the category page rather than implying a trial exists. Full methodology, axis weights, and changelog: /glp-1-supplements/methodology/.
Best creatine supplement while on a GLP-1
We score creatine on dose adequacy against the clinical reference floor, form (monohydrate is the reference standard — "fancier" forms don't score higher, since the evidence doesn't support a performance edge, but they do cost more), verification, and label transparency.
