Are you really that dense! WHy is it so incredibly difficult for you to understand what I am saying. I know the function of Human Microbiota and its role in Maintaining health. I thought the subject was whether Manufactured probiotics establish and whether they cure dysbiosis. This is what we are discusssing. Right!? They do not establish and they do not cure. How can I be more clear. And, yes, I do know a lot about he subject.
