Look, I'm no doctor but I've lived a very long time with digestive tract issues/ailments and learned a few things. The most important are twofold: 1) Doctors don't know everything; 2) Be responsible for your own health and KNOW YOUR OWN BODY! From Crohn's disease to Diverticulitis/dverticulosis, I have had a too long journey through digestive/intestinal tract hell. I have suffered explosive (often bloody) diarrhea and constipation in the same 12 hr period. Doctor's have been of little help. It wasn't until I took control of my own body by changing my diet (hey men HAVE to have certain things in our diet women don't, and there are definitely things guys - especially older guys like me - need to avoid) and adding a few crucial supplements that I was able to find digestive peace and have done so now for two years now. This Garden of Life Omega-Zyme product I initially found in one of the major chain vitamin stores (at a significantly higher price!) a couple of years back. I eventually switched over to the Ultimate Digestive Blend to see if it provided even better results than the good I'd already experienced. I never went back to the the regular blend. Amazon pricing is much more reasonable on top of that. I use this product 3 times a day. Morning, midday and before bedtime after dinner. Used in conjunction with a 50 billion bacteria probiotic product not offered on Amazon (hopefully one day it will) taken once a day, my digestive issues have almost been completely eliminated only (well to be honest: mostly only) arising when I go off my dietary regimen and "treat" myself to too much of bad thing for someone with my particular health issues. Two of my teenage kid's developed the same issues I have (which I in turn think is hereditary as my father and one of my sisters shared these ailments) and I started them on these same two products and there been no more doctor's office visits since. If you want to try something else when other doctor prescribed medications fail or make you sick in other ways. Try this stuff along with a good probiotic supplement. Forget about yogurt. Pasteurization ruins yogurt's ability to offset the "bad" bacteria in your digestive tract with "good" bacteria. Yogurt is a waste of money. Hope this helps someone feel better and get healthy
