I get mushroom products from a website suggested by a nutrionist at a cancer conference. The website is www.fungiperfecti.com They have several different individual and combined types of mushrooms which means there can be fewer to take.
I get Thornes Fractionated Citrus Pectin from several different websites, just put the name in a search engine. Some will only sell to medical professionals, but many don't ask any questions. I buy this in powdered form as it would take so many capsules to get the suggested dose. One scoop (included)) contains the daily dose. I put it in a smoothie for my partner who has stage 4 non small cell lung cancer. Nearly 3 years ago she was given 6 months to 2 years to live. Something is working, natural, traditional? Who knows, who cares? The important thing is she is still here and relatively healthy. Another hint...get a good oncologist, preferably one who is also doing clinical trials. I hear folks saying all the time that their initial one just gave them a death sentence and gave them some same old same old treatment. Ours is great, and never runs out of alternatives. Also, we have found some of the side effects of chemo can be prevented by the use of daily supplements. For example, many people have to have potasium infusions (painful), after the first one I solved the problem with a daily potasium supplement. Similarly, iron...they give you $3,000. shots to keep you from becoming enemic. This seems to work only a while, and then a blood transfusion is required (takes all day). After the first time this happened I began giving my partner 58 mg. of iron daily...she hasn't been enemic since.
Hope this is helpful...and good luck.
