Track nitric oxide levels from home.

The test measures nitrite levels in your saliva, which directly reflect your body’s nitric oxide (NO) availability. Nitric oxide is a vital molecule that supports blood flow, cardiovascular health, exercise performance, and more. By assessing nitrite levels, the test offers an easy, non-invasive way to monitor your NO status in real time.

The test uses a simple biochemical reaction where nitrite in your saliva reacts with specific reagents on the test pad, producing a color change. The intensity of the color correlates with the amount of nitric oxide available in your body. This proven method is based on decades of scientific research and is widely used for nitric oxide evaluation in both clinical and wellness settings.

If your results show low nitric oxide availability, you can take steps to improve it. Eating nitrate-rich foods (like leafy greens and beets), staying physically active, maintaining good oral health, and managing stress all help boost nitric oxide production. Regular testing lets you see how these changes impact your levels, helping you fine-tune your approach for better results.

Nitric oxide is a signaling molecule that relaxes blood vessels, improves blood flow, and helps deliver oxygen and nutrients throughout the body. It plays a role in cardiovascular health, exercise performance, immune defense, sexual wellness, and healthy aging. Low nitric oxide levels can contribute to fatigue, poor circulation, and reduced resilience, making it important to monitor and maintain optimal levels.

Testing frequency depends on your health goals. For lifestyle optimization—such as adjusting diet, exercise, or supplementation—daily or every-other-day testing provides the most insight into how habits affect your nitric oxide levels. For general wellness tracking, weekly or monthly testing may be sufficient. Consistency is key for spotting trends and making informed decisions. Athletes should test more frequently.
