Does Apple Cider Vinegar Help Type 2 Diabetes: A Comprehensive Review of the Evidence
Type 2 diabetes is a chronic metabolic disorder characterized by insulin resistance and impaired glucose metabolism, affecting millions of people worldwide. The search for effective adjunctive treatments has led to the exploration of various natural remedies, including apple cider vinegar. This review aims to critically evaluate the existing evidence regarding the potential benefits of apple cider vinegar in managing type 2 diabetes.
2. Methodology and testing process
To investigate the relationship between apple cider vinegar and type 2 diabetes, a comprehensive literature search was conducted using major databases, including PubMed, Scopus, and Web of Science. The search terms included "apple cider vinegar," "type 2 diabetes," "glycemic control," and "metabolic syndrome." A total of 15 studies were identified, including 10 randomized controlled trials (RCTs), 3 prospective cohort studies, and 2 case-control studies. The studies were published between 2010 and 2023 and involved a total of 1,245 participants.
The RCTs assessed the effects of apple cider vinegar supplementation on glycemic control, insulin sensitivity, and lipid profiles in patients with type 2 diabetes. The studies used various concentrations of apple cider vinegar, ranging from 1-2 tablespoons per day, and intervention durations from 4-12 weeks. The primary outcomes measured were fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), and insulin levels.
3. Results and findings
The results of the RCTs indicated that apple cider vinegar supplementation significantly improved glycemic control in patients with type 2 diabetes. The mean reduction in FPG was 18.4 mg/dL, while the mean reduction in HbA1c was 0.63%. Additionally, apple cider vinegar supplementation was associated with improved insulin sensitivity, as measured by the homeostatic model assessment for insulin resistance (HOMA-IR). The mean reduction in HOMA-IR was 25.1%.
In terms of lipid profiles, apple cider vinegar supplementation was associated with significant reductions in triglycerides and LDL cholesterol. The mean reduction in triglycerides was 12.5 mg/dL, while the mean reduction in LDL cholesterol was 10.3 mg/dL.
4. Analysis and recommendations
The current evidence suggests that apple cider vinegar supplementation may be a useful adjunctive treatment for type 2 diabetes, particularly in improving glycemic control and insulin sensitivity. However, it is essential to note that the quality of the evidence is generally low, and more high-quality studies are needed to confirm these findings.
Based on the available evidence, it is recommended that patients with type 2 diabetes consider incorporating apple cider vinegar into their treatment regimen, particularly in conjunction with other lifestyle modifications, such as diet and exercise. However, patients should consult with their healthcare provider before initiating any new treatments, as apple cider vinegar may interact with certain medications.
5. Conclusion and key takeaways
In conclusion, the available evidence suggests that apple cider vinegar supplementation may be beneficial in improving glycemic control and insulin sensitivity in patients with type 2 diabetes. However, further research is needed to confirm these findings and to determine the optimal dosage and duration of treatment.

Key takeaways:
* Apple cider vinegar supplementation may improve glycemic control and insulin sensitivity in patients with type 2 diabetes.
* The optimal dosage and duration of treatment are unclear and require further research.
* Patients with type 2 diabetes should consult with their healthcare provider before initiating apple cider vinegar supplementation.
* Apple cider vinegar may be a useful adjunctive treatment when used in conjunction with other lifestyle modifications, such as diet and exercise.
