This topic is so confusing, I would like to know the correct amount of the enzymes to take also. They upped my dosage as I was not gaining weight, but I think I’m now maintaining so that’s better than continuing losing - starts to feel like I am just going to fade away when it’s a lower # every time I am weighed (I am 5’ 7” and I weight 109 or so now). But when they upped my dosage (I was taking ZenPep, 20,000 IUs at meals, 10,000 for snacks) they okayed me to order a different, OTC med - Vital Nutrients, so take one of these at my three main meals along with the ZenPep. Much cheaper, $40/month. Now I am wondering what is the difference? - if much - between the ZenPep and cheaper OTC med? I wouldn't have known about the OTC cheaper med if the Dr hadn't recommended it, so they must have some faith in it. Hard to find answers for these medications. And is there much difference between Creon and ZenPep? I think Creon may be more expensive than ZenPep, I pay $194/month from the hospital mail order pharmacy - I’ve seen much higher $$ for both, the mail order option helps us (initially was paying $394/month).
