Isopure Protein Powder = Diarrhea

Was wondering if anyone else has this problem? It's the Dutch chocolate low carb and the Pineapple orange banana zero carb powder. I drink the clear bottle isopure protein frequently.no problems! This is first time a protein powder has given me diarrhea.
I normally buy the nectar but the gnc I went to yesterday doesn't stock it!

I haven't had a problem with Isopure. I have a tub of unflavored and a tub of strawberry cream. The unflavored I use to make a double scoop shake along with a scoop of Champion Whey chocolate. But no distress from it that I've noticed.

If you got the Isopure at GNC they will refund your money within 30 days with receipt.

I used the Creamy Vanilla and the Dutch Chocolate with no problems.  It's sweetened with Splenda, so if you have an issue with that, it could be the problem, although it shouldn't be since that is what the "pure" products are sweetened with as well.    The other difference is that the "pure" is milk protein isolate, while the powder is whey protein. 

Or...what are you mixing it with?  Milk/1/2 n 1/2, heavy cream?  Possible that you have a lactose intolerance?

Just ideas...good luck figuring it out!

I apologize! Sorry, I haven't answered your answers to this post.
I'm not lactose intolerant, but thinking the half/ half(fat) I've been mixing with could be a cause.
Having labs done tomorrow and requesting bacteria cultures while I'm in there. Since this has all came about after hernia repair in February. I thought at first it could be my gut transit time sped up? Or my DS was kickin' in to overdrive, which isn't case initially lost several pounds but scale has went back to same old weight.
I'm a stress eater and my nerves are shot! Carbs are probably the biggest culprit!!!!
Thank you, for answering and please accept my apology for taking so long to answer you all.
