Thanks CJJ. From what I read in Doctor Murray's book and on his website, enzymes are the number one supplement that he recommends for effectiveness. My father isn't on any enzymes as of yet, but we do give him pineapple for the Bromelain. I am planning on giving him MD Fraction Maitake Mushroom and Curcumin also. I do have a worry though that if I give him too many supplements, one may counteract the other. perhaps this is me being paranoid considering the amount of substances making up our food. What are you thoughts on this?
