Thanks for responding.
I know most whey is from cheap milk, but this was supposed to be organic whey ($50 for 14 servings!!) so I doubt the problem came from hormones and antibiotics, I think it was an allergic response possibly caused by leaky gut. I’m just wondering if there is any whey in kiefer, or does it all get skimmed off? I may try it after my joint aches go away. (Hopefully the aches will go away!)
