Questions and evidence-based answers to probiotics

Probiotics are living microorganisms that have beneficial effects on the human body. Food eaten by probiotics is called prebiotics, and the metabolites produced by probiotics are called postbiotics. The number of bacteria indicated on probiotic products means the guaranteed number of bacteria remaining until the expiration date. There seems to be no difference in the effects of probiotics depending on the material from which they are obtained. In general, the strains of probiotics consumed are diverse, and the greater the number of bacteria, the better the effect will be, but more research is needed. It is difficult to say that ingested probiotics must be excreted in the feces to be effective, but the higher the detection rate in feces, the better it seems to have settled in the intestinal mucosa. Finally, it seems that probiotics taken before meals have a higher rate of intestinal delivery than those taken after meals.
