The Truth About Collagen Supplements And Breast Cancer || Dr. Liz O'riordan

Any supplement you take could interact with breast cancer treatments like Tamoxifen and chemotherapy

There is no supplement at the moment that can cure or stop your breast cancer coming back

It’s really important to do your own research to make sure that anything you’re taking is safe, regulated and won’t interfere with your treatment

Thank you, thank you, thank you. Common sense answered my question about collagen but you put the stamp on it. Thank you. 🙏🏻 You are in my prayers. Always.

Collagen made a super difference in my skin and made my fingernails lovely. When not taking it my nails are soft as paper and painful at the tips. Also it helped my psoriasis disappear. A big drawback is that it caused restless sleep and anxiety. That's bc collagen uses up tryptophan, which is necessary to create serotonin and is involved in making melatonin as well. If one takes tryptophan 4 hours after the collagen, then one doesn't get the anxiety or the restless wakeful nights.

Great info. So many patients put their trust in supplements which may help, but they may also interfere with the cancer therapy you are taking.

Very good to know. I've wondered about these products because my skin has taken a beating with all the cancer drugs (and stress). As my mama would say "get your priorities in order" and I know this, but most of us women do care about our skin, our looks, especially going through treatments that have dragged us through the wringer. I know, I know ... priorities.

I feel so blessed to have seen this by chance. I had a breast cancer recurrence while taking Tamoxifen regularly, and no doctor ever mentioned the enzyme to me. It has prompted me to research this enzyme more, and I found out I was taking a weak CYP2D6 inhibitor. I'm going to look into getting tested for that enzymes activity in my body. Thank you.

Please advise how to keep our muscle, bones, skin and brain healthy if you are on Tamoxifen. This obviously blocks estrogen that helps with so many things in our bodies. Thank you. I love listening to you ❤

As much as I love your videos and am in awe of your service to breast cancer patients, I did find this video less than fully helpful. There must be SOME research or background info available on collagen? (You're encouraging people to do their own research but isn't your tag line usually "I do the research so you don't have to"?) Encouraging thought and care (especially about if something you've considering could interfere with the mechanism of action of the drug treatment you're relying on + you only mention tamoxifen here, are AIs similarly affected?) is absolutely needed and warranted, but there are also pharmaceutical drugs that can interfere with each other, so it isn't just supplements you need to take a close look at. And these supplement + diet-based questions are a source of continuing frustration. There are A LOT of us who have co-morbidities (digestive/GI disorders, even something as "simple" as a hiatal hernia/ulcer and/or being on an H2 blocker/PPI or that the drug treatment itself adversely effects our GI system) that impact our ability to eat or digest so many of the foods we're being told are part of a healthy diet. Supplements are something we might have to rely on for nutrition and therefore, we'd actually quite like to have some info on if they are or aren't safe at any phase of treatment, or how they might work/be metabolized. It's quite a tangle as a patient to find sources of reliable information on all these potential interactions--or maybe benefits in our individual situation--& so often, medical providers don't have time or resources to delve into it. (Or maybe there just isn't data available, because there's no money in it for the big companies or it's too difficult to design the gold standard studies that would produce acceptable data.) In addition, many of us don't have access to a nutritionist/dietician, either from location/lack of providers or insurance/affordability. (And many I have tried, when I did have access, were not versed in cancer-related issues or able to adapt to multiple issues effecting dietary needs. Another source of frustration.) I'd love to see videos on what the best sources of reliable info are that a patient can access, or how to assess the information you're looking at, when we want or need to go deeper than even the best Youtube source can offer.

I keep seeing lots of collagen supplement people (Influencers) push the idea that sugar/glucose is whst causes cancer/make cancer grows, but surely taking collagen as it naturally glycosylated is just as bad??

What do you think about soya? I have soya milk every day on my porridge, but now I’ve read that soya might increase estrogen, my BC was estrogen positive

[sherouet]

I suffer from acid reflux and IBS so badly I take omeprazole I can’t take any supplements even the food I eat can’t digest it properly I don’t eat meat or fish it’s just too heavy I am frustrated

[uketlmw]

Can collagen supplements cause lumps in breast or breast cancer ?

[HL-qvyd]

Hi dr Liz, this another great video thanks, I just like to know is fruits ok to eat, like grapes appels because they are sweet? and plant based food? Im not a huge meat eating person, some times eat fish. ❤

[LouLou-joln]

I had a hospital phamacist sit down and tell me not to take any supplements during my chemotherapy treatment, he said the whole aim is to kill cells, not support cell growth. Thank you

Is it ok to eat healthy and eat anti oxidant food ?
