Having Low Levels of this Miracle Molecule Puts You At Risk of a Heart Attack. The Best and Worst Habits to Increase Nitric Oxide Production with Dr. Nathan Bryan
Mon, 24 Feb 2025
This episode is brought to you by Levels and Fatty15. When we think about long-term health and longevity, nitric oxide production probably isn’t the first thing that comes to mind. But today’s guest explains why this crucial molecule plays a key role in our bodies—and the tell-tale signs of low production that can ultimately contribute to chronic disease. Today on The Dhru Purohit Show, Dhru sits down with Dr. Nathan Bryan to explore why nitric oxide is the holy grail of molecules for long-term health—and the top lifestyle factors that can make or break its production. Dr. Bryan ranks the biggest disruptors of nitric oxide, including alcohol, poor sleep, a sedentary lifestyle, ultra-processed foods, and chronic stress, and dives into the latest research on how they impact your body. He also breaks down the critical role nitric oxide plays in disease prevention, from chronic illness to Alzheimer’s. If you’re looking for a masterclass on how to boost nitric oxide production and what habits you need to tweak, this episode is a must-listen. Dr. Nathan Bryan is a renowned biomedical researcher known for his groundbreaking work on nitric oxide (NO) biology. Dr. Bryan's research has significantly advanced our understanding of NO's critical roles in cardiovascular health, immune function, and neurobiology. Beyond academia, he advocates for public health, translating his research into practical solutions for improving human health. His new book is The Secret of Nitric Oxide.

Chapter 1: What is nitric oxide and why is it considered a miracle molecule?
Dr. Nathan Bryan, welcome back to the podcast. We have you here today to talk about the holy grail of health, nitric oxide, and the miracle molecule, as you like to call it. And specifically, we're going to start off today's episode by tier ranking the root causes of visceral fat, inflammation, and disease relating to poor nitric oxide production. Are you game for that? Let's do it.
OK, so we're going to start off with a big one that my audience has questions on, which is alcohol. What's the relationship between alcohol and nitric oxide and where does it fall on our tier ranking system?
Well, I think it's, you know, it's certainly moderate alcohol consumption has some cytoprotective, cardioprotective properties. And so what happens is when you have moderate alcohol consumption, and we're talking maybe one or two drinks every couple of days, right? What that does is it's called alcohol or ethanol preconditioning. And this has been studied for 30 or 40 years.
And the observation was that people who drink moderate alcohol, if they have a heart attack, the heart is a little bit protected from injury from someone who hasn't consumed alcohol. It's ethanol preconditioning. So it's upregulating an enzyme called aldehyde dehydrogenase, which is an enzyme that's responsible for metabolizing and prolonging nitric oxide activity. So there's a clear connection.
However, the problem with overdoing alcohol consumption, you get portal hypertension, you get liver disease, and it destroys nitric oxide production, leads to inflammation, oxidative stress, and immune dysfunction. I think what we're finding is, and the other thing people ask me all the time too, what about drinking alcohol and affecting the oral microbiome? Because we know alcohol-based mouthwash
Kill it. But I tell people, at least when I drink a scotch, I'm not holding in my mouth for 30 or 60 seconds and swishing it around. So the alcohol in spirits in wine doesn't have a resident time long enough in the oral cavity to disrupt the microbiome.
So if you had to give alcohol a grade as it's related to not just nitric oxide, but the whole conversation of visceral fat inflammation. And again, to contextualize it, you're talking about a moderate light level of drinking, right? Where would you put it on our ranking here? All right, we have S is supreme. That means like something is really actually genuinely great for you.
And then we have the classic grades, A, B, C, D, F. Where are we going to put alcohol on this tier rank system?
You know, if we're talking about moderate consumption and not over consumption, again, and this is not my opinion, it's based on published science. But I think it's somewhere in the middle. It's probably a D. I'll give it a D. Can you give it a D?

Chapter 2: How does alcohol consumption affect nitric oxide levels?
But again, in the vapes, there's probably more toxic chemicals in there that outweigh the benefits of a little bit of nicotine.
What I'm seeing a lot is people using these nicotine little pouches and kind of keeping in their mouth. You're not a fan of that.
Not a fan. No, personally, I wouldn't do it. I mean, anything that chronically constricts blood vessels to me is about chemists and physiologists and the biomedical sciences I stay away from.
Let's talk about one of the most controversial topics of maybe the last five years, but especially right now, if I had to rank it. Yeah. Seed oils. Talk to us about seed oils, your thoughts on them. Because from everything that I've seen out there, and we've had people on all sides of the spectrum that have been on this podcast, people will tell you that universities like Harvard and Tufts
And the nutrition schools at a lot of our elite institutions are saying that not only are seed oils not bad for you, but they seem to have some sort of protective benefits that are out there. Then the other side, let's call it the Maha movement, the individuals that are out there that are saying, Hey, these things have been used for industrial lubricants. These things are not benign.
And just because there are observational studies that are out there that show that seed oils typically are associated with better health, that doesn't mean there aren't downsides related to it, like trans fats from overuse of seed oils. Where do you fall on the spectrum of seed oils and how would you rank it? All right, I got a question for you.
What if you could track your food, sleep, exercise, blood sugar, and key biomarkers all in one place? Well, I have good news for you. With the Levels app, this is not only possible, it's actually needed if we're gonna fix our broken healthcare system.
You wanna hear something pretty shocking that I learned from the Levels founder, Josh Clemente, recently on this podcast, is that there are so many people who are unhealthy and they don't even know that they're unhealthy. We have over half of US adults that have prediabetes or diabetes, and just these two conditions alone set the stage for things like Alzheimer's, heart disease, and even cancer.
That's why it's so important to use technology, things like the Levels app, to stay on top of your metabolic health and stay on top of all your biomarkers and your exercise and your sleep and the tracking of your food. I've had to use a bunch of different apps to do this. Now with the Levels app, I can do this all in one place.

Chapter 3: What are the dangers of smoking and its impact on nitric oxide?
But like Dr. Twyman, who's a good friend and a great cardiologist, he doesn't rely on this. He complements functional endothelial test, FMD, flow media dilatation, which looks at the functional production of nitric oxide in the lining of the blood vessels and then correlates it with a biochemical test. Then you really get a complete clinical picture. So the answer is they can have utility.
And we may bring them back because really what we're measuring is how well is your oral microbiome. And if you have a good diet and a good oral microbiome, then we can move the needle on these test strips. And that gives people something good because people want to see changes.
A lot of times you don't feel the effects of nitric oxide, but you can certainly see it on these test strips in your fasting sugar, in your fasting insulin, in your blood pressure, in your sexual function. But people, it's a nice show and tell. For sure.
Nice show and tell, has some limitations. That's right. Ultimately, you want to make sure you're doing all the right things that are there. We're going to be talking about some of them. And eating the right foods, we're going to be talking about some of them. Did you want to do anything else with these test strips?
Well, I'll just show what we're doing. And the reason this is so important, and we may bring them back, is because the effects of toothpaste, daily oral hygienic practices have such a profound impact on the microbiome and nitric oxide production. But with this mouth rinse, we've recapitulated the effects of a healthy salivary pH environment. And so in these mouth rinses,
We can actually, if you use it, I'm not a big fan of mouth rinse. I don't even, maybe I'll use my mouth rinse, but I don't need to. As I've shown you, I can do what I'm doing now, maintain healthy microbiome. I haven't had a cavity since I was five years old. I brush twice a day. I don't floss, but I eat a healthy diet and take care of myself.
So there's really no need for me to take my own mouth rinse. Well, maybe, maybe not. But people who don't, people who want to take a mouthwash and who want a fresh breath, they don't have a fresh breath otherwise, then this becomes extremely important. That could be helpful. It could be very helpful.

Chapter 5: What role do ultra-processed foods play in nitric oxide levels?
That's 99% of the things that people stress over. Right. So what I do is it's, and it's still saying, it's not what happens to you that matters. It's how you respond to what happens to you that matters. So, You know, I live a pretty stress-free life.
And it doesn't mean that there's not stressful things around you.
People apply a lot of stress to me. I just don't stress over it because if I can't control it or change it, what good does it do? It's not going to change the situation. No, but what we have to do is affect the, you know, there's something called adrenal fatigue and the adrenal glands secrete these things like adrenaline, these stress hormones and cortisol.
So when you have an elevation, chronic elevation of cortisol, I mean, that's a normal stress response. We need that acutely. But when you're chronically stressed, then it completely shuts down and disturbs other hormones and the whole endocrine system.
And it'll eventually shut down nitric oxide production because you're inflamed, you develop oxidative stress, and you develop an immune dysfunction.
So part of what I'm hearing you saying is that there's this chronic stress that so many people are wrapped up in. It could be physical stress on the body from an ultra-processed diet. It could be not dealing with the toxic people in your life and putting up boundaries, you know, other examples of that. But stress in itself, like doing a cold plunge, that's a little bit stressful.
So there's good stress. There's bad stress that's there. So stress isn't the worst thing for us. We shouldn't fear it, but we should look at the areas that it's overruling our life and the root causes that are contributing to it.
Yeah, we call that hormesis in terms of how the body adapts to, because when we exercise or when we go for a run or when we do a cold plunge, it's an acute stress on the body. So the body then transduces an adaptive response. So like resistance training, there's intermittent hypoxia when we contract our muscles. It's squeezing on the blood supply. and then it's causing intermittent hypoxia.
So the body responds with angiogenesis. We're creating more blood vessels. So now with that same resistance, we're not developing hypoxia because now we revascularize that tissue. We develop, you know, we build more protein, we build more muscle, and that's, you know, the benefits of weight training.

Chapter 8: How does hydration affect nitric oxide levels?
So the body responds with angiogenesis. We're creating more blood vessels. So now with that same resistance, we're not developing hypoxia because now we revascularize that tissue. We develop, you know, we build more protein, we build more muscle, and that's, you know, the benefits of weight training.
For instance, when we run, you know, if you're doing a marathon and you're running for two to three hours, you're completely diverting blood flow away from the kidneys, the intestines, and some people can develop ischemic organ disease. But the body adapts to that and go, oh, I don't want to run out of oxygen again. I need more mitochondria. Turns on mitochondrial biogenesis.
It improves the oxygen utilization. So now that cell can make more energy with less oxygen. And why is that? Because it was confronted, it dealt with a stress, an acute stress. And that's kind of like the cold plunge. When I go from the sauna, 170 degrees to 37 degrees, it's flexing the blood vessels. Because when you're hot in a sauna, your blood vessels are maximally dilated.
trying to rid the body of the heat so it doesn't overheat. Then when you go to cold, the body's trying to preserve heat so it constricts all the blood vessels. But for me, it's like weight training for your blood vessels because there's smooth muscle that's around all the blood vessels and it's working them out. But it's stressful. But the adaptive effects to that acute stress
are undeniable i would look at the system that we have and i would take something like stress we got a guy with you know putting his hand on his head in front of a laptop it probably could be like a b or c in the sense that it depends if it's a controlled stress chronic stress will kill you chronic stress will kill you yeah but a control stress stress that you choose is actually really helpful so i'm going to throw it on here under c as a place to say that it depends either way
Because really good stress for you could be an A or maybe even an S in certain situations. Absolutely. Okay. A sedentary lifestyle, specifically walking less than 4,000 steps a day, which the CDC says is sedentary. How bad is that for you? Talk about both nitric oxide and anything that you know when it comes to keeping a healthy body composition.
Well, we have to move. I mean, humans are designed to be mobile, to move. And yet most Americans aren't. We get in our car, we drive to work, we sit for six, eight, ten hours a day. Nobody gets exercise. And then the calories we consume through diet are stored as fat and become unhealthy.
But we have to move and kind of scientifically explaining this because exercise has been shown to stimulate nitric oxide production. And that's why exercise is medicine. You're giving your body activation and stimulation of nitric oxide. The other thing is kind of an electrical, you know, we're electrical beings, right? We diagnose death through loss of electrical activity, EEG or EKG.
So we have to maintain electrical conductance and flow and current and maintain voltage across cell membranes. Muscles are what we call piezoelectric, meaning that when we contract muscles and we move muscle, they're muscle battery packs. So they're creating voltage. And through the fascia, through these meridians, those muscle battery packs supply different organs with certain voltage.
