Vinegar fermented from apples; the active compound is acetic acid.

Genuinely blunts the glucose spike after a high-carbohydrate meal, though the effect is small and short-lived.

This needs saying plainly. The viral 8 kg figure comes from a single trial that the journal formally retracted on 25 September 2025, citing statistics that were not possible and raw data that could not be relied on. A meta-analysis published the same month reporting 7.5 kg pools that retracted trial, so it cannot be trusted either.

Nothing to do with sleep.

What remains is a small post-meal glucose effect. Nothing wrong with that — just far smaller than advertised.
