I have had a problem these last few months. Each time after drinking my whey protein shake, I get diarrhea within 4-6 hours. Like I said, I've had his problem since end of October. When I don't drink my protein shake I'm fine. I have never been lactose intolerant in the past, but then again, I don't like milk so haven't drank much. Do you have anything on this? And if this is the case, do I have any options for an alternate protein supplement? Thanks for your help!
This is quite the coincidence, as I just made a thread about this in another sub-forum.
Long story short ON whey isolates was killing my digestion, leaving me bloated and with the ability to poop through a screen door. I thought for a while that I might be lactose intolerant, but I had my doubts (especially after my wife had a similar experience with my protein).
I finally decided to give whey protein another try and went with All the Whey this time, and have had no problems. So my issue with my ON protein had to be something other than lactose intolerance.
My advice would be to try a different protein company. Just order a 2.5lb container, or ask for a sample.
If it turns out that you are actually lactose intolerant, egg protein may be a good alternative for you.
