Nitric Oxide Indicator Strips by HumanN
Nitric Oxide Indicator Strips by HumanN provide a quick, non-invasive way to evaluate your body’s nitric oxide production using a simple saliva sample. Developed with research collaboration from the University of Texas Health Science Center, these strips measure salivary nitrite — a key biomarker required for nitric oxide availability in the body. Nitric oxide plays an important role in circulation, vascular signaling, and exercise performance, making these strips a practical tool for monitoring lifestyle and nutrition changes.
Key Benefits
• Provides immediate feedback on nitric oxide production
• Simple at-home wellness test
• Helps monitor dietary nitrate intake (beets, leafy greens)
• Useful for athletes and active individuals
• Tracks response to nitric-oxide-supporting supplements
How It Works
Dietary nitrates are converted by oral bacteria into nitrites, which are then used by the body to produce nitric oxide. The indicator pad on each strip reacts with nitrite in saliva and changes color. The resulting color is compared to the included chart to estimate nitric oxide availability.
Suggested Use
Wash hands and collect saliva on fingertips. Apply saliva to the indicator pad. Do not place the strip in the mouth. After approximately 30 seconds, compare the pad color with the color chart provided in the package.
Who Can Benefit
• Individuals supporting cardiovascular wellness
• Athletes monitoring performance response
• Users of beet or nitrate nutrition programs
• Individuals evaluating vegetable intake
