Nitric Oxide Test Strips let you quickly check your nitric oxide (NO) levels at home with results in just 10 seconds.
Nitric oxide is an important molecule your body makes that supports healthy blood flow, circulation, blood pressure, and oxygen delivery to your muscles and organs. Think of it as your body's natural way to keep blood vessels healthy and relaxed.
The test uses your saliva to measure two things: whether you're eating enough nitrate-rich foods (like beets and leafy greens), and whether you have the right beneficial bacteria in your mouth to convert those foods into nitric oxide.
As we age or deal with health challenges, our body's ability to produce nitric oxide naturally goes down, which can affect heart health, energy, and performance.
By testing regularly, you can see how your diet, supplements, and lifestyle choices affect your NO levels.
If your results show low nitric oxide, you can make simple changes—eat more beets and greens, take NO-supporting supplements, or adjust your routine—then retest to see improvement.
Each box contains 50 test strips for ongoing monitoring.
How to use
How to use
Test at least twice daily—once first thing in the morning before eating or drinking, and again 1-2 hours after consuming nitrate-rich foods (beets, leafy greens) or NO-supporting supplements.
Place test strip on tongue to collect saliva, fold over to transfer sample to test pad, hold for 10 seconds, then compare color to provided chart.
Can be used multiple times throughout the day for regular monitoring.
For best results, mouth should be clear of food and liquids for 1 hour prior to testing.

Frequently Asked Questions
What is nitric oxide and why should I test it?
Nitric oxide (NO) is a molecule your body produces that acts as a signaling molecule for many important functions.
It helps blood vessels relax and widen (vasodilation), improving blood flow and oxygen delivery throughout your body.
NO supports healthy blood pressure, cardiovascular function, immune response, brain health, and athletic performance. As you age, NO production naturally declines, which can affect circulation and overall health.
Testing helps you understand if your body is producing adequate NO so you can make dietary and lifestyle adjustments to support optimal levels.
How accurate are these saliva test strips?
These strips measure nitrite levels in saliva, which indicate the presence of dietary nitrates and the oral bacteria that convert them to nitric oxide.
While they don't directly measure circulating NO in blood (which would require lab testing), clinical research shows that saliva test strips provide a reliable indicator of your body's ability to produce NO through the nitrate-nitrite-NO pathway.
They're best used as a monitoring tool to track trends over time and assess how diet, supplements, and lifestyle changes affect your NO status.
When is the best time to test?
Test first thing in the morning before eating or drinking to establish your baseline NO status.
Then test again 1-2 hours after consuming nitrate-rich foods (beets, leafy greens, arugula) or NO-supporting supplements to see how your body responds. You can test multiple times throughout the day to monitor patterns.
Avoid testing right after using mouthwash or antibiotics, as these can kill the beneficial oral bacteria needed for NO production and may temporarily lower your results.
What should I do if my test shows low nitric oxide?
Low NO levels suggest you may need to increase dietary nitrates, support your oral microbiome, or consider NO-supporting supplements.
Increase consumption of nitrate-rich foods like beets, beetroot juice, arugula, spinach, and other leafy greens.
Consider supplements like Vascanox HP or NOx Synergy from Designs for Health.
Avoid overusing mouthwash (especially antibacterial types) which kills beneficial oral bacteria. Regular exercise also boosts NO production.
Retest regularly to track improvements as you make these changes.
