I just found out one of my best friends has leukemia...?

Although I see a thump down on Jim answer, I have to say that I heard about this Immunocal stuff, and seems it does some wonders. I found out the word while I was doing some research on Glutathione and Mark Hyman, M.D. in his blog mention the word "Immunocal" under the 9 Tips to Optimize your Glutathione Levels. His blog can be found at http://www.huffingtonpost.com/dr-mark-hyman/glutathione-the-mother-of_b_530494.html. Also your friend can see some more info at this other site posted by Medicine.net. http://www.medicinenet.com/script/main/art.asp?articlekey=50746
