Probiotics/prebiotic supplementation represents a viable option for addressing systemic inflammation and chronic disease risk resulting from excessive body weight. The purpose of this feasibility study was to determine if 90-d of supplementation with prebiotic and probiotic could alter mRNA responsible for inflammation and subsequently metabolic health in weight stable overweight adults. Participants were advised to not change their diet or exercise habits during the study. All protocols were approved by the University IRB and participants gave written informed consent. Participants were randomly assigned to either placebo (N=7; rice flour) or combined (N=8) prebiotic (PreticX® Xylooligosaccharide; 0.8 g/d; ADIP) and probiotic (MegaDuo® Bacillus subtilis HU58 and Bacillus coagulans SC-208; 3 Billion CFU/d) and measurements were made at baseline, 30, 60, and 90-d. Whole body DXA scans (GE iDXA®) and blood 574-plex mRNA analysis (Nanostring®) were used to generate primary outcomes. Compared to placebo, supplementation was associated with a 36% reduction in visceral adipose tissue (p = 0.001). Supplement resulted in significant, differential expression of 15 mRNA associated with adipose tissue inflammation, systemic inflammation, and/or chronic disease risk. The key findings support that 90-d prebiotic/probiotic supplementation may be associated with an improved metabolic health, reduced adipose tissue inflammation, reduced systemic inflammation, and reduced chronic disease risk. Collectively these findings demonstrate the potential of a prebiotic/probiotic supplement to impact metabolic health risk independent of weight loss in free-living individuals.
