How to boost nitric oxide to lower inflammation and live longer

TL;DR

Nitric oxide keeps arteries relaxed, guards against inflammation, and helps lower blood pressure over time. Daily intake of nitrate-rich vegetables and beetroot supports its production, while antiseptic mouthwash can hinder it and reduce nitrite formation in saliva. Movement also raises nitric oxide through increased arterial shear stress, contributing to long term cardiovascular health.

Transcript

So, there is a gas that your body makes deliberately, 24/7, all the time, inside the lining of your own blood vessels. And this survives, this gas survives about a second before it disappears. It's called nitric oxide. I talk about it literally all the time in most of my videos. And we actually use a synthetic version of it in emergency medicine an... Read More

Key Insights

• Nitric oxide is a gas produced by the endothelium that helps relax arteries and lower blood pressure, reducing long term cardiovascular risk.
• The nitrate from leafy greens is converted to nitrite by oral bacteria and then to nitric oxide in the stomach, linking saliva to circulation.
• Vegetables like rocket, spinach, chard, celery, and beetroot are rich in nitrates and can lower systolic pressure by a measurable amount over time.
• Antibacterial mouthwash reduces salivary nitrite levels and can cause small increases in blood pressure after starting use.
• Daily consumption of nitrate rich greens is recommended to maintain steady nitric oxide production, rather than sporadic intake.
• Movement increases nitric oxide production because arterial shear stress activates endothelial enzymes that synthesize the gas.
• Beetroot juice can lower blood pressure quickly in healthy volunteers, but whole vegetables are preferred for overall health value.
• Processed meat nitrates differ from vegetable nitrates in their combination with protecting nutrients and potential to form harmful nitrosamines when cooked at high heat.

Questions & Answers

Q: How can I raise nitric oxide levels through diet on a daily basis?

To raise nitric oxide levels daily, include nitrate rich greens in meals such as rocket, spinach, chard, and celery, and add beetroot when possible. The body converts these nitrates first to nitrite in the mouth via oral bacteria, then to nitric oxide in the stomach, helping lower blood pressure over time. Aim for regular intake across meals.

Q: What role does saliva play in nitric oxide production?

Saliva serves as a critical conduit for nitric oxide production. Nitrate from vegetables is reduced to nitrite by bacteria in the mouth, which then travels to the stomach where stomach acid converts nitrite to nitric oxide. This process links oral bacteria to systemic circulation and helps regulate blood pressure.

Q: Why should I avoid antibacterial mouthwash if I want to raise nitric oxide?

Antibacterial mouthwash can reduce the population of oral bacteria that convert nitrate to nitrite, lowering salivary nitrite and subsequent nitric oxide production. This can lead to a slight rise in blood pressure over days of use, though dentists may still prescribe it for specific conditions when benefits outweigh risks.

Q: Does movement really affect nitric oxide, and how much should I exercise?

Yes, movement increases nitric oxide because blood flow drags along the artery lining cells, which sense this shear and activate the nitric oxide producing enzyme. The video emphasizes that starting from sedentary and adding movement yields significant benefits, with increasing returns up to a point before plateau.

Q: Which foods should I prioritize for nitric oxide rather than relying on juice?

Prioritize whole nitrate rich vegetables over juice. Whole foods provide additional nutrients and fiber, and research shows beetroot juice lowers blood pressure, but whole vegetables are recommended for a more robust, sustained effect and better overall health outcomes.

Q: What is the relationship between nitric oxide, cholesterol, and inflammation?

Nitric oxide helps keep the endothelium smooth, reducing friction that can trap cholesterol and immune cells. When nitric oxide production declines, the endothelium becomes stickier, enabling cholesterol accumulation and inflammatory immune response, which over decades can form plaques leading to heart attack or stroke.

Q: Are nitrates in vegetables different from nitrates in processed meats?

Yes, vegetable nitrates come with vitamin C and polyphenols that steer them toward nitric oxide production, whereas processed meat nitrates can form harmful nitrosamines when cooked at high heat. The transcript notes these are not the same and highlights the protective context of vegetables.

Q: What is GTN and how does it relate to nitric oxide?

GTN stands for glyceryl trinitrate, a synthetic version of nitric oxide used in emergency medicine and cardiology to dilate arteries quickly during a heart attack. This demonstrates the potent vasodilatory role of nitric oxide and its clinical relevance for acute cardiovascular events.

Summary & Key Takeaways

• Nitric oxide is a protective gas produced by arteries that helps keep blood vessels flexible and blood pressure stable, reducing long term cardiovascular risk.

• Nitrate rich vegetables like rocket, spinach, chard, celery, and beetroot feed nitric oxide through a mouth and stomach conversion process involving oral bacteria.

• Antibacterial mouthwash can dampen nitric oxide production by killing oral bacteria, which lowers nitrite formation and subsequent nitric oxide synthesis.

• Regular movement increases nitric oxide by promoting blood flow and mechanical shear on the endothelium, triggering nitric oxide production.

• Eating leafy greens daily is more effective for nitric oxide levels than sporadic consumption, as the effect wears off after about a day.

• Whole foods are preferred over juice for nitric oxide boosting to ensure additional nutrients accompany nitrates.

• Be mindful that processed meats with nitrates can form nitrosamines, unlike nitrates from vegetables which come with protective compounds.

• Applications in medicine, such as GTN, demonstrate the powerful vasodilatory role of nitric oxide during emergencies, underscoring its centrality to cardiovascular health.
