Many of us with CFS/FM are aware that undentured whey is part of Dr. Cheney's protocol due to its ability to raise L-glutathione levels and strong detox and antiviral effects. It seems that according to Dr. Cheney's discoveries, it can be one of the single most important elements toward recovery from CFS/FM. The problem is, this stuff is expensive. Right now, I'm using Immunocal, which is costly. I'm looking for another inexpensive brand that is just as effective that does not contain flavorings and other additives. ProHealth's product, Immunplex looks good, but I can't take it because it has vanilla and alpha lactalbumin, to both of which I have delayed food allergies (as does everyone with CFS and fibromyalgia, whether they know it or not). So, I'm wondering if there's anyone out there who has found a source for an inexpensive, but effective brand of this product.
