Is There a Subgroup of Probiotics?

People still misunderstand about probiotics, and I try so hard to clear this up. Just like when we talk about vitamins, we are talking about a class of different things that operate in different ways. They have totally different roles, and you have totally different needs for each of them. So just like vitamin A is not the same thing as vitamin E, strain for immunity is not thesame thing as a strain for mental health,.
