Brief Summary
Probiotic supplements improve IBS symptoms through manipulation of the gut microbiota. Metabolites derived from microbiota metabolism and host-microbiota co-metabolism have an impact on host intracellular signalling pathways. Although probiotic supplements improve IBS symptoms, the precise composition of probiotics that can achieve optimal response remains unclear. SMT04 (M3XTRA, GenieBiome Limited, Hong Kong, China) is a novel product that is commercially available as a dietary supplement in Singapore. It consists of a patented probiotics blend of 5 probiotics (3 Bifidobacteria and 2 Streptococci with 12.5 billion CFU in 1 sachet). Probiotics preparation that included varying composition of Bifidobacteria and Streptococci strains had previously demonstrated efficacy in achieving symptom improvement in IBS patients. Streptococcus thermophilus, a component of the blended probiotics, significantly improved intestinal functional barrier in healthy subjects. Thus there is potential for SMT04, a dietary supplement, to be a treatment option for IBS patients. This is a multi-centered trial, all data and samples from the study sites will be pooled together for analysis.
