All the zenpep does is provide the mechanism for the adsorption of nutrients out of the food you take in. Are you with a partial pancreas still or without it totally as I am. Without the zenpep, if you are w/o a pancreas, you basically are just passing the food through your system w/o adsorbing any of the nutrients from the food. If you’re still with a partial pancreas then you are providing some digestive enzymes and the zenpep is just being used as a supplement to what you can still produce. Best to find it and take them with your meals and snacks as suggested by your surgeon.
