protein powder giving me the runs

2 days ago i though i got food poisoning (or maybe i did) but i had the runs REAL bad and my stomach hurt like **** all night. Well i was a little better the next day cause i coudlnt eat anything but the runs have come back and i have to take a **** some times every half an hour and it really hurts like burning
i was trying to figure out what it was and i just figured out that it was some new protein powder i got from costco cause i just got it a couple days ago...
any1 ever had this happen to them??

Try switching to a Whey Isolate type of protein.

ON 100% whey gives me the ****s like hell. It really sucks when you take a shake 30min before you work out. Then your squatting and it hits you like a truck. That ****s up your desire to finish your workout.

Are you using creatine at the same time? I had a similar problem and attributed it to protein supplements, but it turned out that my creatine wasn't mixing properly and was sitting in my gut with poor absorbtion, which caused me pretty severe, erm, digestive discomfort.

Switch to an isolate. You can check out true protein.com's isolates. They have some great flavors and low prices.
