Short answer: The headline ACV weight-loss claim rests on a study that no longer exists in the scientific record — a direct, unhedged statement of the claim's actual current evidentiary status.
Why "not supported" is the specific verdict, not "unproven"
This isn't a case of insufficient evidence — the single trial this rests on was retracted in September 2025 over statistical and data-integrity failures, actively removing the prior supporting evidence.
Why this claim still appears in marketing despite the retraction
The finding went global. It is still the study underneath most ACV weight-loss marketing you will see today — marketing materials often lag behind, or simply ignore, retraction notices.
What this means for your purchase decision specifically
Skip it if you're buying the ACV weight-loss story — a direct recommendation given this claim's actual evidentiary status.
