Nitric Oxide (NO)

Nitric oxide is a naturally produced signaling gas molecule in the human body that regulates blood flow, oxygen delivery, stem cell mobilization, and energy production. Its age-related decline is the earliest event in the onset and progression of chronic diseases.

Endothelium

The endothelium is the single layer of cells that lines every blood vessel throughout the body. These cells are responsible for producing nitric oxide, and their inability to do so leads to constricted blood vessels, inflammation, and stiff arteries, initiating cardiovascular disease.

Vascular Age

Vascular age is an objective measure of biological age, distinct from chronological age. It can be assessed by examining carotid intima media thickness, flow-mediated dilatation (endothelial function), and other markers like histone modification or methylation profiles, comparing an individual's vascular health to age-matched databases.

Oral Microbiome

The oral microbiome refers to the diverse community of bacteria residing in the mouth. Specific nitrate-reducing bacteria within this microbiome are crucial for metabolizing dietary nitrate (from vegetables) into nitrite and then nitric oxide, a biochemical pathway that humans cannot perform independently.

Telomeres

Telomeres are protective caps located at the ends of chromosomes, preventing DNA from fraying during cell division. Shorter telomeres are associated with a shorter lifespan, and nitric oxide plays a role in activating the telomerase enzyme, which helps prevent telomere shortening.

Mitochondrial Function

Mitochondrial function refers to the process by which mitochondria within cells produce cellular energy (ATP). In age-related chronic diseases, there is a reduced number of mitochondria per cell and impaired function, while nitric oxide signals the cell to increase the number and efficiency of mitochondria, generating more energy with less oxygen.

Hygienic Hypothesis of Disease

This hypothesis suggests that reduced exposure to diverse microorganisms, particularly during childhood, can lead to an increased susceptibility to allergic and autoimmune diseases. Epidemiological data supports that children growing up in rural, 'dirtier' environments tend to have better immune function and lower incidence of chronic diseases later in life.

?
What is nitric oxide (NO) and why is it important for health?

Nitric oxide is a naturally produced signaling gas molecule that regulates blood flow, oxygen delivery, stem cell mobilization, and cellular energy production, making it foundational for human health and longevity.

?
What are the common symptoms of low nitric oxide levels?

The first sign is often erectile dysfunction, followed by increased blood pressure, metabolic disease, diabetes, and exercise intolerance, as these conditions are linked to impaired blood vessel dilation and cellular function.

?
How does nitric oxide deficiency contribute to chronic diseases like Alzheimer's?

Nitric oxide deficiency reduces blood flow to the brain, causes insulin resistance (leading to 'diabetes type 3'), increases inflammation and oxidative stress, and impairs immune function, all of which are root physiological causes of Alzheimer's disease.

?
Why do many blood pressure medications fail to work for some patients?

Many common blood pressure medications, such as ACE inhibitors or calcium channel blockers, are not designed to restore nitric oxide production, which is often the underlying problem in cases of resistant hypertension.

?
How does the oral microbiome relate to nitric oxide production and overall health?

Specific nitrate-reducing bacteria in the oral microbiome are essential for converting dietary nitrate from vegetables into nitrite and then nitric oxide, a process humans cannot perform independently, making a healthy oral microbiome critical for NO levels and systemic health.

?
What are the negative effects of using antibacterial mouthwash?

Antibacterial mouthwash kills the beneficial oral bacteria necessary for nitric oxide production, which can lead to an increase in blood pressure, negate the cardiovascular benefits of exercise, and disrupt the overall microbiome, contributing to systemic disease.

?
Is fluoride harmful, and should it be avoided?

Yes, fluoride is described as a known antiseptic, chemical toxicant, thyroid toxicant, and neurological toxin with no proven benefit and significant risks, including lowering IQ in children and shutting down thyroid function.

?
How do antacid medications impact health, particularly nitric oxide levels?

Antacids suppress stomach acid production, which is crucial for breaking down proteins and absorbing essential nutrients like B vitamins, selenium, and iron; this nutrient malabsorption and altered gut environment can indirectly affect nitric oxide production.

?
Can nasal breathing improve nitric oxide levels?

Yes, nasal breathing activates the nitric oxide synthase enzyme in the epithelial cells of the sinuses, delivering NO gas to the lower airways and pulmonary arteries, which improves oxygen uptake and helps lower blood pressure.

?
What is the role of sugar in nitric oxide deficiency?

Sugar is a toxin that causes an elevation in blood glucose, which sticks to and inactivates the enzyme responsible for making nitric oxide, and also destroys the oral microbiome, leading to a significant reduction in NO production.

?
What is the link between oral infections and cancer?

People with solid tumors almost always have active oral infections (e.g., root canals, cavitations), suggesting a strong association where these infections may set the stage for cancer cell growth and proliferation, although direct causation is still being explored.

1. Eliminate Antiseptic Mouthwash

Cease using antiseptic mouthwash as it destroys the oral microbiome, which is essential for converting dietary nitrates into nitric oxide, and can negate the cardiovascular benefits of exercise.

2. Avoid Fluoride Products

Stop using fluoride toothpaste and be mindful of fluoride in municipal water, as fluoride is an antiseptic that kills the oral microbiome necessary for nitric oxide production and is also a neurotoxin.

3. Strictly Avoid Sugar

Eliminate sugar and high glycemic index foods from your diet because sugar binds to and deactivates the enzyme responsible for nitric oxide production, and it also disrupts the oral microbiome.

4. Prioritize Nasal Breathing

Engage in nasal breathing to activate nitric oxide production in your sinuses, which dilates bronchioles and pulmonary arteries, improving oxygen uptake and lowering blood pressure.

5. Practice Tongue Scraping

Regularly scrape your tongue, ideally with a copper scraper, to increase the diversity of your oral microbiome and improve oral health, but avoid using antiseptic mouthwash immediately after.

6. Get Daily Sunlight Exposure

Aim for 20-30 minutes of daily sunlight exposure, as both UV and full-spectrum infrared light stimulate nitric oxide release, which supports energy production and can lower blood pressure.

7. Engage in Moderate Exercise

Perform moderate physical exercise for 15-30 minutes daily to activate nitric oxide production in blood vessels, which is crucial for cardiovascular health and overall well-being.

8. Avoid Aluminum in Products

Do not use products containing aluminum, such as certain antacids, as aluminum is a toxicant that should be absolutely avoided.

9. Incorporate Humming

Practice humming regularly, as certain frequencies can activate the nitric oxide synthase enzyme in your sinuses, potentially increasing nitric oxide levels, provided the enzyme is functional.

I'm absolutely convinced this will eradicate and cure Alzheimer's.

Dr. Nathan Bryan

No one is interested in curing human disease because medicine is a business.

Dr. Nathan Bryan

If the scientific community can figure out how to restore the production of nitric oxide, it will change the world.

Lou Ignaro (quoted by Dr. Nathan Bryan)

50% of the men over the age of 40 self-report erectile dysfunction. That's in the U.S. So think about that. 50% self-report. I think the numbers are higher because most 40-year-olds that I know are never going to admit that they have erectile dysfunction.

Dr. Nathan Bryan

Dose dictates poison.

Dr. Nathan Bryan

Kids need to be dirty.

Dr. Nathan Bryan

I don't care what the question is, that's the worst answer you could provide, just because we're doing it because that's the way we've always done it, right?

Dr. Nathan Bryan

The body is electric, and we're batteries.

Dr. Nathan Bryan

So your health span is really probably the more important thing to be focusing on, not your lifespan.

Steven Bartlett

I'm at the point of knowing now that the future of medicine and healthcare around the globe is going to be dependent upon nitric oxide product technology.
