Apple cider vinegar: a quick fix for oxidative stress?
NCT ID NCT07414875
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a single dose of apple cider vinegar, taken with a meal, changes levels of a substance linked to oxidative stress in the blood of adults with obesity. 46 healthy obese adults were randomly assigned to either receive apple cider vinegar with a standard meal or just the meal alone. The goal was to see if the vinegar had an immediate effect on oxidative stress markers.
