01/03/2016 - Getting a weird immune response/allergic reaction to this. Wondering if it's not good for people with autoimmune illness (celiac in my case). I've gone off of it and got on it several times to confirm that this is what's causing the weirdness. 04/11/2016 - Tried this supplement again, and presently have the worst, most raging migraine of my entire life. During midterms. Yeah. Go, me! I didn't learn my lesson the first time. I have confirmed that immunomodulators like AHCC are not supposed to have these kinds of effects on people with autoimmune problems, and the only thing I can imagine might be going on is some kind of contamination of this product. I really wish this product worked. I had very high hopes. I've never had this kind of reaction to *any* supplement, in my life... and I've tried many. Wish I didn't spend over $110 (it's presently $180, which is pretty messed up of them to jack the price so much), for something that had to be thrown in the trash. Read more
