Hello. Today’s topic is on non-small cell lung cancer. We’re going to discuss that and how it relates to vitamin D status in your body. And as usual, my regular is to go over a case study about… Or actually we’re doing a double-blind placebo study review today, on how vitamin D can affect non-small cell lung cancer. So, I’m going to share my screen here. Let’s get this going. And so, this is the study. It is right here from the Clinical Cancer Research journal. What year is it? 2018. So, titled, Vitamin D Supplementation and Survival of Patients With Non-small Cell Lung Cancer: A Randomized, Double-Blind, Placebo Controlled Trial.

So, we’re going to go over this and the reason I’m going over this is because, for those of you that don’t know me, I am Dr. Dylan Foster, I’m a Chiropractic Physician. I’ve been practicing since 1997 when I graduated from Life West. Since then, I got certified in Functional Medicine and Oncology Nutritional Counseling. So, I’ve done a ton of postdoctoral training, thousands of hours of extensive training in the field of helping people get healthier. Health and nutrition is, probably the best way to describe it is, figuring out the causes and addressing the causes. There’s the other side, the medical side, is more about addressing the symptoms and treating the symptoms and that’s okay. I think both sides should be working together to be honest with you. There’s a lot of people out there that think only one side matters and it doesn’t matter. But I think teamwork, helping people the bottom line is getting you better. That’s the bottom line. That’s all that matters.

So, what I’ve devoted my life to now is, helping people that have been through chemotherapy and radiation therapy. Two is probably the most extreme situations that I can possibly imagine. And then also using traditional therapies are the two most toxic substances on the planet from radiation and chemotherapy. That’s why they come with this new [inaudible 00:02:12] side effects, which leads me to Post Chemo Nutrition. My goal is to help people get rid of those side effects as fast as possible, so you can get your life back on track because as you know life is very precious, very precious indeed. And we need to make the most out of it and we don’t need to do, I hear a lot of people do, I got better in a year or two years or just someday I’ll get better. You’re missing all that time with your friends, your family, your loved ones. You’re feeling miserable, you can’t think you can’t function, you’re not enjoying life and that’s not what it’s about.

So, that’s why I have Post Chemo Nutrition here. This is my website, And the reason I’m talking about vitamin D today is because if you go to my products, I have two main products that’s all I have. Those are the main ones that’ll help people with most situations, with what they’re dealing with. Because bottom line is Cell Revive helps with mitochondrial function and inflammation and cellular repair. That’s what Cell Revive is for is to revive your cells back to life, back to health. And then you use Bindatox to reabsorb any heavy metals, toxins, radiation, chemicals, whatever you got going on in your body. It helps pull them out, grab them, bind them and remove them, get them out of your body, which most do not do that. Most just move them around and you got a big dust storm and you feel worse than you did when you started.

So, Cell Revive is one of my main products here, obviously. And it’s got, as you can see actually it’s, what it is is AM/PM packet, if you didn’t know that. So, you have an AM and a PM packet that you take with multiple pills and capsules in each packet. Now what’s in each packet is right here. There’s actually another side, so this is just part of it. But one of the things that’s in it is I got vitamin D in here. So, you can see vitamin D right here and we have 5,000 IU that’s a high dosage. A lot of people think that’s too high. But like I said, part of why I do what I do is because, I base my training and my knowledge off of not just research, but you’re going to see tons of research studies in here, but also on experience. And I have tested and done blood work on thousands of patients, I’ve done postdoctoral training through, what is it, Southern California, no, San Diego State University, sorry.

So, I did some on that on vitamin D with all medical doctors and studies on vitamin D and the importance and everything I’m finding is that we need to have our levels be at about 50,000. And the study that we’re going to look at, does 1200 IUs a day and I found 1200 IUs works but it’s going to take years to get you feeling better and doing better. Because usually again, everybody I’ve done, I’d say 95% of my patients I’ve seen that I’ve done blood work on, which has been a lot, have had very low vitamin D levels. Well below 50,000 micrograms per nanometer, I believe is what it is. But anyways, what we want to do is take in a lot of vitamin D up front to get our levels up quickly and then you don’t need to be taking it. So, this is not a long-term supplement. So somebody you’re thinking, Oh, that’s expensive and I can’t afford that.

It’s not long-term it’s just to get you better and when you’re better, you stop taking it. And 5,000IUs is the best dosage I’ve seen that works across the board. And vitamin K is with it because it helps it work better, absorbed better and you get more benefits out of it in absorption, which is key factor here. All right so, study-wise I was telling you, education. If you go to my website, we go to education, we scroll down to research and then you’re going to see our two products under the research page. So, I’m going to click Cell Revive when it comes up. Looks like my Internet’s going a little slow here. There we go. So here’s Cell Revive, we’re going to read the research and we’re going to go to, obviously, we’re going to go to Advanced-D. By the way, here’s all the studies that I’ve found to help me maximize, or not maximize, but utilize the nutrients that are in Cell Revive and why I use them.

So, these are mostly medical studies and medical books. It’s mostly studies and journals. So you can see, I have dozens, if not over a hundred in here, but we’re going to scroll down until I get to Advanced-D. Here we go. So vitamin D supplementation, let’s see, we’re going to do one on non-small cell lung cancer. Here it is right here. So, this is the one we’re doing today. And then you can see there’s a lot of other studies on vitamin D and cancer prevention and breast cancer survival, things like that. So, you look through those obviously in our website, but this is the one we’re talking about today, which is right here. Here’s the article it’s in PubMed. It’s basically, I want to edit it so I just kind of downloaded the PDF part. So, let’s go over it. I’m just going to give you a brief overview because I’m not going to get into all the, how they tested and people and stuff. So basically, I’m going to cover the highlights here.

And it’s kind of a tricky, I shouldn’t say tricky, but it’s got some good and bad to it. So, it all explain a little bit. So high serum 25 hydroxyD, so it would just say vitamin D levels, are reportedly associated with better survival in early-stage non-small cell cancer, lung cancer. Therefore, they want to find out whether vitamin D supplementation can improve the prognosis of these non-small cell lung cancers. So, that’s what this study was done to figure out. Now they’ve taken people kind of a small group, they got 77 people they used that took vitamin D and then 78 that didn’t and that were placebo. What they found is that the relapse in depth occurred in 28% and 17% of the patients in both of these groups. So, 28 and 17%. It wasn’t very significant difference in either survival rates with both of these groups, whether they took vitamin D or placebo.

However, here’s the caveat, what’s interesting the ones that had low vitamin D levels that supplemented had a much higher and better five year survival rate than the ones that didn’t supplement, that are the placebo group, I should say. So basically, what it’s going to go on to is say is that as it scrolls down here, I don’t know if it’s right here, patients that had low vitamin D and I believe they’re saying 20, I’ll get to it. Let me go over the review here. So basically, what it’s going to show you is that there are some benefits to supplementation. They already had to be low on your vitamin D levels. In patients with this non-small cell lung cancer, vitamin D supplementation may improve survival in patients with early-stage lung adenocarcinoma with lower 25 (OH)D levels. That’s one of your tests that you do, it’s the main test that people do when they test your blood vitamin D levels. That’s the one I did in my practice the most.

That’s the conclusion, it may help people with survival that have lung cancer, but that already had lower vitamin D levels, basically, than the ones that didn’t. So, let’s read through some more here, vitamin D is hypothesized to prevent cancer relapsed through inhibiting cell proliferation, angiogenesis, and metastases while inducing apoptosis, and differentiation. So, basically what they’re saying is vitamin D definitely helps prevent cancer in many different aspects from the spreading and nutritional blood flow to it. And there’s a lot of studies that will confirm this on my website. Indeed, patients with early-stage non-small cell lung cancer who had surgery, this is interesting, the people that had surgery during the summer months with the highest vitamin intake or the highest serum levels, because we get vitamin D from the sun, right? So in the summer, they had a better prognosis than patients that had surgery during the winter or low vitamin D intake. And they had lower vitamin D levels in their body. Interesting, huh?

So, just the time of year, if you’ve had more sun, you have a higher chance of survival. But how’s again? It’s related to your vitamin D levels in your body. So, here they talk about that a 1200IUs of vitamin D for a year and it raises, oh, this is from another study they did so I based it off of this from a Parkinson’s study. So excuse me, jumping on here. So Parkinson’s study, they found that 1200IUs a day for a year raised their levels from 22.5 micrograms per milliliter to 41.7, that’s a good jump. What’s interesting about this though, is that they’re going out for 41.7. All of my functional medicine training, this is on personal side now, states to be healthy, to have really good healthy levels you need to be at about 50. Not 41, not 22. Anything below 30 is from what my training was, is considered your cells can no longer repair and regenerate.

30 to 50 is when they maintain status quo, but they don’t heal and repair, which is good status quo. If you’re good and you’re healthy, but anything above 50, is where you want to be for healing, repairing, regenerating, having optimal health and wellness. Now there is a point of too high and I believe it’s around 90. You don’t really want to be above 90, so you always got to get them tested once in a while. Based off of this study here, they went ahead and use 1200IUs for this vitamin D trial, which in my practice, I never found 1200 IUs raise stuff significantly and very quickly. And they’re even saying this raised at a decent amount, but it took a year, so that’s a long time. In my practice what I found is, higher levels raise it quicker. And that’s the key because people want to feel better faster they don’t want to wait a year or two, three years to feel better.

So, let’s scroll down here we’ll go through just a little bit more information then back to the highlights. So different regimens, including higher doses and longer durations may lead to different findings. So, even what they’re saying one of their weaknesses is, it was a small case study only for 155 people. They didn’t do it very long they only did it for a year. Let’s see. And then also they feel like if they had higher doses, it might have helped and longer duration also it may lead to different findings. Which I personally agree with, I think that would have been very helpful. So, the bottom line about this vitamin D article is that if you go in for a cancer surgery and you’re dealing with non-small cell lung cancer, if your vitamin D levels, according to this study are below 20, then you are going to have a higher risk of nonsurvival unless you supplement. If you supplement, you’re going to raise your survival rates.

Now, for those of you in the study that already had higher than 20 for your vitamin D level, your survival rate didn’t really change much if you took a vitamin D supplement. And now occurring, this is 1200 milligrams. Also, it doesn’t say what kind of vitamin D they’re using. So I know, and that’s an interesting point, I know in my research that you have to use what’s called D3. And I’ve learned a lot of medical doctors and seen a lot of medical doctors use D2 for supplementation and that’s not an absorbable vitamin D form. So, that’d be interesting to find out. I don’t know why it doesn’t say it, I don’t know how you’d find out to be honest with you, but it would be nice to see if what were they were using… I mean, I talked about this test they did that they just don’t see what vitamin D supplement was used. So, I guess you’d have to contact the doctors that did the study, the researchers.

So anyways, sorry, off tangent again a little bit. But yeah, see here that’s saying people that have less than 20 had less survival unless they supplemented. Sorry, off tangent that my brain going here. Vitamin D is important, as you can see on my research page, I have a ton of research articles on the benefits of vitamin D from different cancers. You can read through those, but ultimately this study is stating vitamin D supplementation works very well for those that already had low levels of vitamin D before they went in for any types of treatments for their non-small cell lung cancer. So that’s it, that’s from Clinical Cancer Research from the American Association for Cancer Research website. So other than that, I am Dr. Dylan Foster, please visit my website One thing I like about my website is if you go to the main page, I have a wonderful, amazing health questionnaire quiz that you can take right here to see your overall health score based on a hundred.

Took me a long time and a lot of research to put together all the questions that basically relate to people’s overall health. So, if you take post chemo nutrition and you want to get healthier, this quiz is good to give you a baseline score to see where you’re at, so you know where you’re going and when you can stop. So, that way you can get the most out of it. And what I found in my experience in my practice is that a lot of people stop before they should have, because they’re starting to feel better, but not as good as it could have felt. And so, then they stopped and then they start regressing back to where they were slowly. We’re trying to keep the feeling good, keep you enjoying life, keep you having a great time with your friends, your family and maximizing the time that you have on this planet. So again, I’m Dr.Dylan Foster I look forward to hearing from you, please take care. God bless. And I’ll talk with you soon.
