Impact of Multistrain Probiotic Supplementation on Glycemic Control in Type 2 Diabetes Mellitus—Randomized Controlled Trial

Abstract

Hyperglycemia, a key characteristic of type 2 diabetes mellitus (T2DM), highlights the need for effective management strategies. This study aims to analyze the impact of multistrain probiotic supplementation on glycemic control in T2DM patients. During a 24-week randomized controlled trial involving 130 participants, subjects were assigned to either a probiotic group or a placebo group. The key outcomes included fasting blood glucose (FBG), postprandial blood glucose (PPBG), glycated hemoglobin (HbA1c) levels, and lipid profiles, assessed at baseline and post-intervention. The results indicated a significant reduction in HbA1c (p = 0.004) and increased HDL-c (p = 0.023) and improvements in lipid profiles in the probiotic group, alongside a trend toward decreased FBG and PPBG. No serious adverse effects were reported, indicating good tolerance of probiotics. These findings suggest that probiotics may positively influence metabolic parameters in T2DM patients, supporting their potential as a complementary dietary intervention. Further research is needed to understand the underlying mechanisms and enhance probiotic formulations for diabetic control.
