Description

Apple cider vinegar (ACV) is a fermented liquid rich in acetic acid and bioactive compounds, often used as a dietary supplement for its purported health benefits, especially for blood sugar regulation, weight management, and digestive support.

Main effects with level of evidence
Moderate
Note on evidence

There is moderate human evidence for effects on postprandial blood sugar and modest weight changes; other uses are less substantiated.

Blood Sugar Regulation

Moderate

ACV may reduce post-meal blood sugar levels and improve insulin sensitivity, especially in people with insulin resistance or type 2 diabetes.

Particularly relevant for: People with impaired glucose tolerance · Individuals with type 2 diabetes

Weight Management

Moderate

Regular use of ACV is associated with modest reductions in body weight and body fat, likely due to enhanced satiety and reduced caloric intake.

Particularly relevant for: Overweight adults · Individuals seeking weight loss

Digestive Health and Antimicrobial Effects

Limited

ACV exhibits antimicrobial properties that may support digestive health and help inhibit harmful bacteria in the gut.

Particularly relevant for: General population · People seeking gut health support
