DOES IT WORK?
Results vary. ACV is overhyped by wellness influencers but not completely worthless. The acetic acid does have small clinical trials showing modest blood sugar reduction after meals. Weight loss effects are minimal. It's not magic, but it's not snake oil either. Just don't expect miracles.
