Myself & DH have used pumpkin protein and fermented pea protein with no issues (I'm vegetarian, although he isn't). Also, keep in mind that many folks get pinned gas if they consume large amounts of water/liquid after eating/taking food supplements etc., so mind your liquid intake after meals and such. That may help. I personally, have to drink room temp or warm water as well. Chilled liquids always eventually lead to painful gas.
Hope you find something agreeable!
