ParaGone recommends taking ParaZYME at the same time, which contains probiotics and enzymes for healing the intestinal lining. I would definitely be taking probiotics to help strengthen your immune system at this time.
I also had alot of cramping with the ParaGONE. I think this is just part of the cleansing process. In the first two weeks, I passed so many worms and hard fecal matter. I think this is just a very strenuous time for your system. I only have 4 days left on the program with very little symptoms at this point.
I know Antibiotics cannot tell the difference between the friendly bacteria and the bad ones they have been taken to fight. They kill them all. As for ParaGONE, I really think the specific herbs it contains is aimed only at the bad bacteia, worms, and parasites. However, it certainly would be a good idea to make sure you take the probiotics just to be safe.
