i hear this from alot of people that " probiotics dont colonzie". I believe that is partially true. "Transient" probiotic treatments dont colonize and colonization is also prevented when there are too many biofilms/pathogens stuck to the intestinal mucosa.
If fermented foods didnt colonzie over time then all theraputic healing diets are all void. GAPS, weston price and all other healing diets have healed people and changed their gut floras. The gut flora does change in time if apply enough effort and time.
fecal transplants are not accessible easily to people and if it were believe me i would get one every 2 months.
there is a new product going through the FDA at the moment called RBX2660 which is a Fecal Transplant suspension enema kit that will easily allow people to inject probiotics through the rectum. I bet, this will be highly expensive but it will definitely make a change in peoples health. But to deny all microflora therapys dont work is a farce.
