Conclusions
Lactobacillus acidophilus
Nevertheless, the results of this study suggest that supplementation with active probiotics of Bifidobacterium, Lactobacillus acidophilus and Enterococcus faecalis is safe, although it does not reduce the risk of IGT conversion to DM. More clinical and laboratory studies using large samples and long-term observation are needed to explore the effects of different probiotic strains on IGT. This pilot study was designed to provide preliminary data to conduct more conclusive hypothesis testing.
