How the studies fall
What the evidence shows
Erythritol is essentially **glycemically inert** — it is absorbed in the small intestine and excreted unchanged in urine without being metabolized for energy, so RCTs and reviews consistently show no meaningful rise in glucose or insulin. This zero-glycemic profile is the whole basis for its use in diabetes and keto products (and, ironically, why its blood levels rise so sharply on ingestion — the

| Mazi & Stanhope 2023 · Nutrients | observational | supports | moderate | In-depth review: erythritol absorbed then excreted unchanged, no caloric/glycemic contribution. |
Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
