This is so much better than zenpep. You take this once a day. Free advice: always take your enzymes, probiotics, mtc, etc, on an empty stomach so it can help rebuild your gut health instead of just band-aiding it along. I used to take awful trips down the hall, literally, like 10-15 times a day. My doctor's weren't really helpful. I researched and researched, chose this product on sheer numbers and I can say that it's really helped me. Along with other things, habits and products. Intermittent fasting really helps too.
