What is Nitric Oxide?

Nitric Oxide (NO) is a molecule that helps relax and widen blood vessels, improving circulation, oxygen delivery, and overall cardiovascular health. It also supports energy levels, endurance, cognitive and sexual function.

Nitric oxide plays a crucial role in maintaining good oral health. It helps to improve blood flow and supports the body’s natural defenses against harmful bacteria. Additionally, it aids in saliva production, which is essential for keeping the mouth clean and neutralizing acids that can erode tooth enamel. Without enough nitric oxide, these functions can become compromised, leading to various oral health problems.

Brush thoroughly, at least twice a day, or as directed by a healthcare provider. Use desired amount on a toothbrush.

Many users report an immediate clean mouth feeling with fresh breath.  Within a couple of days, an improvement in the oral microbiome and normal salivary pH.  Many people also report an increased energy and better circulation within days. However, consistent use over a few weeks yields the best long-term benefits.

Dr. Nathan Bryan Talks Nitric Oxide on FOX & FRIENDS

Dr. Nathan Bryan joins FOX & FRIENDS to discuss the critical role of nitric oxide in overall health, energy, and longevity.
As a leading expert in the field, Dr. Bryan breaks down how this essential molecule supports circulation, heart health, brain function, and immune support—and why so many people may be unknowingly deficient.

“We have known for more than 100 years that poor oral hygiene leads to increased risk of cardiovascular disease. Today we know that the oral microbiome responsible for optimizing nitric oxide production accounts for the oral systemic link. Stringent antiseptics, fluoride and poor oral hygiene all disrupt the oral microbiome. Our nitric oxide focused line of oral care products supports the oral microbiome, improving nitric oxide production thereby improving oral and systemic health.”

Healthier Gums. Brighter Smiles. More Confidence.

Your oral health thrives on strong circulation, healthy gums, optimal microbiome and optimal performance. But as you age, nitric oxide production declines—leading to weaker gum health, reduced blood flow, and less vibrant oral health.  Furthermore, the use of fluoride toothpastes, antiseptic mouthwashes lead to a loss of nitric oxide production. 

That’s why we created the CardioSmile Nitric Oxide Toothpaste—a revolutionary formula designed to boost nitric oxide levels, improve circulation, and support gum health, so you can enjoy a healthier smile every day.
