Immunocal is supposed to be a superior type of whey protein. I've taken other whey products but have never tried Immunocal (it's expensive!) but I've heard some great testimonials from people who have taken it and I thought I'd share my mother-in-law's.
My M-I-L has some kidney damage from the blood pressure medicine she has taken. Her doctor told her that she would have to go on dialysis so she went to another doctor. The second doctor told her she was not ready for dialysis yet but would be soon. After 5 weeks taking the immunocal she had a test done on her kidneys and her doctor told her very surprised that there was a slight improvement and that that never happens, what are you taking?! She also has had blotches on her skin and dark circles under her eyes, both of which are gone. She says she has a lot of energy and gets up in the morning feeling good. Also, I don't know if this is related but she had a cataract operation last week and it healed very quickly. She had the bandage taken off in 2 days. Her doctor was surprised.
