If the Cyrex shows red for all dairy markers, so that includes casein, cow’s milk, casomorphin, butyrophilin, but it’s green for whey protein. Should the patient try introducing whey protein? The patient has low glutathione and may benefit from whey.

Dr. Amy Nett:  I think it’s reasonable to try introducing whey protein. So if there are no antibodies out of range for whey protein, absolutely worth a try, and remember, these tests give us a starting place. They’re not the gold standard. So just have your patient introduce whey protein when all other things are fairly stable. There’s not a lot of other variation. So a pretty good baseline, try whey, don’t change anything else for about two weeks and see how the patient does. I think that’s perfectly fine.
