There is lactose intolerance and there is casein allergy - both components in milk and also found in whey protein concentrate.
Whey protein isolate is a very purified version of whey and my question is are there any here who have found an issue with whey alone (in the form of whey protein isolate)?
And if you have found an issue with whey alone, what do you think may be causing it?

Whey still contains lactose, including whey isolate. If you are highly lactose intolerant, it would explain the reaction.

I am casein and whey allergic. I used a very pure Japanese whey isolate product that is without filler, fats, or anything but amino acid whey. I take it post training. I tolerate it better than other dairy, decently. Still react with nasal mucous a bit. But less so.
Started taking BioCor digestive enzymes (the Now Foods dairy enzymes use that companies enzymes) with it and it is tolerated much better. Look into that.

Whey protein made me feel awful - In Feb 2012 bought a big bag of pure whey protein and started drinking it mixed in water, about 30g a day. It made me ridiculously thirsty, for every whey protein shake I had I was drinking about 4 pints of water, within days I broke out in big red spots down my entire back to my butt crack. and my knees and elbows ACHED. It was then that someone suggested I might have food intolerances, which in turn led me to the paleo diet :)

Most Whey is so heavily processed, the body works very hard to figure out how to process it. Only a healthy, non allergic system can do any good with it.
We've switched to Pumpkin Seed Protein Powder and it's added vitamin and amino acid profiles have done what Whey could never do.
It's not expensive and can be found organically. The high amount of Tryptophan works as a mood lifter and sleep aid, when the sun goes down. Can't recommend it enough.

I don't have issues with lactose, but do with casein. If I touch most anything made of cow milk, I get acid reflux. Weirdly enough I can eat certain Haagen Dazs ice creams, but not always.
I know the issue is the casein, because I've no issues with goat milk/yogurt/cheese, nor buffalo mozzarella.
Never had a problem with pure whey powders, except once - but that's because I mixed it in with yogurt. I haven't noticed any difference between isolate or concentrate, perhaps the levels of casein are too low. Certain places such as protein factory can mix up whatever you want, and they can include casein, if you ask for it.
Lactose intolerance will give you flatulence soon after consumption, and I never had that.
Hope this helps.
