Interesting. So how do you diagnose or find out that you have a parasite that feeds on the probiotics? I have gotten a stool test and they haven't detected a parasite (done by Genova). The other option I have heard was that its die off of bad bacteria and someone told me to hold out for 2-4 weeks to see if it gets better eventually. I'm not sure what to do exactly. parasites are something i have not looked into really bc i never thought it was a problem.
