Beta Glucan and herceptin
I have read on the board a while ago and checked with my onc about beta glucan needing to be activated for herceptin to be effective (pten pathway.)
I believe it is found in mushrooms particularly oriental ones. Are there any other natural sources or do you need supplements to obtain sufficient amounts? Ellie |
Re: Beta Glucan and herceptin
Just for this reason, I took maitake mushroom supplements. I had a specific regime. I took 9 capsules per day (545mg standardized) for the week during Herceptin (3 days before, day of, 3 days after). During the rest of the time I took 4 per day. I still take 4 per day now.
Oatmeal also contains beta glucan but you just need to take enough to make a difference. The dose was my own idea. I am still here so who knows what I ended up doing right? |
Re: Beta Glucan and herceptin
Thanks becky
i think it was a post from you that brought beta glucan to my notice. I had remembered maitake mushroom supplements but have had a lot of difficulty getting it here in England. I am now hoping to import some from the states. Is there any particular brand you think is good? Thanks Ellie |

Re: Beta Glucan and herceptin
Hi ladies - I met with an integrative medicine doc who has 'prescribed' Maitake D-fraction extract. 53 drops twice per day, every day. She says the research looks promising! She strongly urged me NOT to take antioxidants when treatment is done. Evidence shows over consumption of them can proliferate cancer cells!

Re: Beta Glucan and herceptin
Hi Leslie
Can I just clarify what you meant by antioxidents? Do you mean vitamin and mineral supplements? Thanks Ellie |
Re: Beta Glucan and herceptin
Hi Ellie,
Yes, any supplement that is considered antioxidant such as Vit C. She says eating foods rich in antioxidants is fine, but do not supplement in pill or liquid form and don't juice! She says we should not try to achieve moe than 100% of any nutrient and that's exactly what supplements do, is exceed the 100% RDA. I was going to start taking antioxidants as soon as my treatment is done. Now I will consult with a naturapathic doctor as well and see if I can decide who makes more sense. Leslie |
Re: Beta Glucan and herceptin
Oh and, the Maitake D-Fraction is not an rx so she didn't really 'prescribe' but recommended.

Re: Beta Glucan and herceptin
Thanks Leslie
The juicing is interesting. I often do an occasional juice when I get days when I have not managed to get any fruit and veg. Guess it's people who juice all the time that may have the problem Ellie |
Re: Beta Glucan and herceptin

Re: Beta Glucan and herceptin
Here are a few studies I found. One is specific to monoclonal treatments, like Herceptin and Rituxan. There are 3 listed here. All of them are very early and small studies so we must use some caution in applying results to the entire population. The results in beta-glucan / anti-cancer research are impressive, however, and more research needs to be done in this area.

Re: Beta Glucan and herceptin
Thanks Tanya. I forwarded the studies to my naturopath. I have taken Maitake with Reishi and Shitake every day for 11 years. I also cook with shitake and the other mushrooms when I can get them. I never needed shots for my blood counts, so I think the mushrooms with beta glucan help. I read that even common white mushrooms and other common mushrooms are healthier than most people think, so I use them for cooking too.

Re: Beta Glucan and herceptin
Hi: I am taking Host Defense Mushroom capsules (these are a mixture of various mushrooms) and I noticed that they contain cordyceps extract (a type of mushroom). I recently read on Herbs 2000.com website that women who have had breast cancer should not be taking cordyceps. Has anyone else heard about this?
Thanks |
Re: Beta Glucan and herceptin
Although a great herb for boosting immune function, apparently it is not good for hormone positive breast cancer. Not sure if you have hormone negative.

Re: Beta Glucan and herceptin
This is on the Memorial Sloan-Kettering Herb site and mentions one animal study with possible increased progesterone production. See the summary below followed by the link.
Mechanism of Action Cordyceps stimulates the number of T helper cells, prolongs the survival of lymphocytes, enhances TNF-alpha and interleukin 1 production, and increases the activity of natural killer cells in cultured rat Kupffer cells (3). Enhanced proliferation of erythroid progenitor cell in the bone marrow of mice is also shown (8). One study suggests that cordyceps can stimulate progesterone production in animal cells (5). Another study shows that cordyceps may be effective against tumor celIs by down-regulating MHC class II antigen expression (7). In addition, anecdotal data suggest reduction of cyclosporin and aminoglycoside-induced renal toxicity, although the mechanism of action is not known (4). http://www.mskcc.org/mskcc/html/69193.cfm |
Re: Beta Glucan and herceptin
Does the integrative doc point to any study regarding antioxidant supplementation? What I can find doesn't seem to support that notion. Seems to be issues regarding certain supplements with certain treatments though.

Hi Tanya
What is a natural source dorBeta Glucan.My wife is allergic to mushrooms |
Re: Beta Glucan and herceptin
PibiKay,
Bakers yeast, oats and barley are also considered sources of beta-glucan. Most studies that I am aware of are based on the mushroom source. I did a quick pub-med search and did find some very positive (albeit small & animal based) studies with yeast-derived beta-glucans. |
Re: Beta Glucan and herceptin
Pibikay,
I've just got BetaGlucan from my "supplement" doctor. It's in soft gel form and made from black yeast (if I remember it right. I'm in hospital for Chemo taking, will look at its package once back home). This product is from Japan. Hope this helps Gift |
Re: Beta Glucan and herceptin
I did a search on Maitake mushrooms and found alot of interesting articles that might be interesting to those who want to know more about mushrooms.
