Its too early for me to tell what its done for my digestion yet, but I got it mostly to help increase my GLP-1 production and it dang sure seems to do the job there! Within an hour or two I can feel it working in my stomach. Cravings are cut by like 80% and stay gone well into the evening. Apparently this isnt even the strongest dose either. Each capsule contains 1 billion units, whereas you can find some brands with over 300 billion units per capsule so if I develop too much of a tolerance to these pills I can easily find something stronger but so far these are working just fine. I like them. Will return for more when this bottle is gone.
