So you are saying a person can look totally healthy. Have normal bowel movements however because of biofilms hiding the bacteria what bacillus subtilis did was help to break up the biofilms setting the bacteria free which is what has happened to me and the rest?
Well i do not really think so. i am not sure why are you so adamant on thinking bacillus subtilis is such a good bacteria.
Different people tolerate different things. Maybe bacillus subtilis is not suitable for some?
For example the gut bacteria in an african native is different to those living in the us.
