I was told to avoid whey protein isolate, high doses of lactobacillus - no more than is in Activia yogurt, grapefruit, and blood oranges. Any supplement that activates the immune system will counteract Prograf, which is an immunosuppressant. I learned from my pharmacist when I was first diagnosed with AML that I can't take anything without checking with my oncologist first.

I hope you find this helpful. Good luck with the shakes!
