Comparison of Apple Cider Vinegar and Metformin Combination with Metformin Alone in Newly Diagnosed Type 2 Diabetic Patients: A Randomized Controlled Trial

ABSTRACT

Objective: This study aims to compare the effect of metformin monotherapy with the combination therapy of metformin and apple cider vinegar on the parameters of Body Mass Index and glycemic control of recently diagnosed type 2 diabetes mellitus patients. Methods: A total of 126 patients were enrolled in this open-label randomized controlled trial, divided into two parallel arms Group I (Metformin 750 mg alone per day) and Group II (Metformin 750 mg+Apple Cider Vinegar 2 tablespoons per day) and assessed for weight, Body Mass Index, Fasting Blood Sugar and Hemoglobin A1c after which the post-treatment values of the aforementioned parameters were compared between the two groups. Informed consent from all patients and ethical approval from the institutional ethics board was obtained. A p-value of <0.05 was considered significant. Results: All the parameters underwent a significant reduction in the pre and post intra group comparison of each group (p-value<0.001). Moreover, a significant difference was found in the post-treatment comparisons of the Fasting Blood Sugar (p-value<0.001) and HbA1c (p-value=0.04) in between the two groups. However, no significant difference was obtained in the post-treatment comparisons of weight and Body Mass Index in between the two groups. Conclusion: Apple Cider Vinegar in combination with Metformin appears to be more effective in improving glycemic control versus Metformin monotherapy.
