Kassaian N, et al. - In a double-blind, randomized, placebo-controlled parallel-group clinical trial, the researchers evaluated the impacts of probiotics and synbiotic on glycemic indices in prediabetic individuals who were at risk of type 2 diabetes and its complications. For the purpose of this investigation, 120 prediabetic adults took part and were randomly allocated to receive either probiotics or synbiotic or placebo supplements for 24 weeks. Researchers reported that glycemic improvement by probiotics and especially synbiotic supplements in prediabetic people had been supported.
