I had some mild diarrhea and GI distress in my pre-op diet including whey protein, but street surgery the whey protein and whey protein isolate absolutely killed me; super painful diarrhea. I started using plant based and I feel much better.
My questions are, one, can anyone recommend a whey alternative that isn’t gross? Two, is there anyone who can tolerate Genepro but not other whey protein? I’ve heard so many people rave about the Genepro in terms of taste, digestion and how readily it dissolves but I don’t want to buy it if it’s just going to make me sick!

Any interest in Collagen protein?

Any interest in collagen Protein?

I agree with this. I could tolerate whey protein and the protein shakes pre-op, but I find them disgusting now. Collagen peptides are the only thing that saved me. There is a very slight taste, but I've mixed it into a lot of things and I don't even notice it.
Now, I don't eat beef, and the collagen is made with bovine hide, but I just accepted it as a necessary, but temporary, evil until I can get all my protein from food. I'm just mentioning it in case bovine hide would be something you don't want in your food.
