Does Apple Cider Vinegar Blood Glucose Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Apple Cider Vinegar Blood Glucose Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - The pooled results using a random-effects model showed that daily ACV intake significantly reduced body weight [SMD: -0.39; 95% CI: -0.63, -0.15; p = 0.001; I 2 = 62%], BMI [SMD: -0.65; 95% CI: -1.05, -0.26; p = 0.001; I 2 = 83%], and WC [SMD: -0.34; 95% CI: -0.67, -0.02; p = 0.04; I 2 = 61%]. [Castagna A (2025); evidence level 1] - Sensitivity analyses excluding high-risk-of-bias studies confirmed the robustness of ACV's beneficial effects on body weight and BMI. [Castagna A (2025); evidence level 1] - Subgroup analyses suggested that ACV consumption significantly improved anthropometric parameters when administered for up to 12 weeks, at a dose of 30 mL/day, and in adults who were overweight, obese, or had type 2 diabetes. [Castagna A (2025); evidence level 1] - Background: Apple cider vinegar (ACV) is a naturally fermented beverage with potential metabolic health benefits; however, its effects on weight loss remain controversial. [Castagna A (2025); evidence level 1] - Although several meta-analyses have reported favorable outcomes associated with vinegar consumption, the overall strength and quality of the available evidence have not been comprehensively evaluated. [Shahmohammadi F (2026); evidence level 2] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
