Protein causing stomach pain

[Chips]

Last year I had H.Pylori a stomach bacteria. Anyway This year I thought it came back but apparently the pain is only there when I drink this protein shake I have. It's a low carb one, and last year when I had the pain I was on the same one. Do any of you know of or experienced this yourselves? If so anybody have an info on this?

dont really know but different types of protein affect me differently

when i bought pure whey protein isolate that stuff went right through me so i no longer use it

u may want to try a different protein powder

I have had trouble with protein powders in the past, mainly gas and cramps. Optimum Nutrition protein seems to be fine for me try it I mix mine with whole milk and I have no digestive problems.

You know what....It's that Whey Protein isolate that kills me too. Maybe I should try a different kind.

you may be lactose intolerant. i had the same problems until i realized i was LI, then switched over to pure (read: not blended) whey isolate. make sure its not a combination of concentrate and isolate. iso has a higher biological value (iso: 90-98% protein, con: 70-85%), and is pretty much lactose free, which means its alot easier on your body. no problems so far, so long as i get in some fibre.
