they cant keep it is very difficult for consumers to discern the companies and product that have solid scientific backing versus those that are taking advantage of them i worry that this sort of pollution in the marketplace could have negative effects on the valid products when they come to market what is your opinion on probiotic supplements do healthy adults need to supplement given that most supplements contain only a few different bacterial strains how effective are these in rebuilding gut flora wrecked by antibiotics there are many mixed findings on probioticssome very promising reports that they are effective other reports that show no effects or even harmful effects it is complex since the supplement market is flooded with poor quality products labelled with the wrong bacteria name or containing no viable organisms but even for good quality probiotics there is likely to be range of success depending upon the individual since the microbiota is a bit different in each of us many of these probiotics were isolated from different fermented foods therefore i prefer to consume feremented foods as way to take probiotics
