Hi, Jeff. My husband has suffered many years with the constant diarrhea. I put him on Dr. Schulz's #2 Intestinal Formula. Don't do the #1 Formula. After one jar of it, he is seeing good results. The diarrhea has stopped and he is cleaning out the plaque at the same time. He told me he is going alot more than he is eating. This is great! This formula also helps with the parasites.
