Thanks for that brilliant question. I would argue that if both CarbRepel and our DigestiveEnzymes worked as designed, you would not take them together. One helps you digest carbohydrates (CHO) so you can comfortably absorb them, and one blocks them, albeit there are other ingredients that may help digest other macronutrients in the Digestive Enzyme supplement. That said, depending on the primary goal of the user, I would suggest not using the 2 together and decide if overall digestive support is more important or blocking CHO is the priority because they simply can’t reduce their intake of CHO. But I have to say – you nailed it!
