  • Quick relief! Way faster than others I’ve tried.

    They say it works within 15 minutes and it was right! Others I have tried take hours to work and don’t last long. This product was great. I was able to eat foods that usually bother my stomach! Thank you!!

  • No issues after eating what I love.

    My favorite dessert is ice cream and it wreaks havoc on my stomach. I took this beforehand and ate Apple Pie A La Mode and had no issues. I'll continue to try this before certain foods. It definitely helped.

  • Good Quality!

    I usually stay away from food that doesn't agree with my body. I like these pills because the pills are small and easy to take. They have no aftertaste, and I didn't get any bad reaction.

  • No more bloating.

    My tummy always get hard when I eat oily food. So I take this an hour before eating out. It does help. No more bloating and no more belly pain. I also go after 4 hours. I can tell this helps digest the food better and faster. I am happy with the result.
