How to Test

Testing is simple, fast, and noninvasive. 

  1. Test first thing in the morning before eating, drinking, or brushing your teeth. 
  2. Place the end marked “saliva here” on your tongue for 5 seconds. 
  3. Fold the strip in half so the pads meet, and gently press for 10 seconds. 
  4. Compare the color on the pads to the chart printed on your test tube. 

Results appear in seconds. The darker the pink, the higher your nitric oxide levels. 

How to Test

Why Test Nitric Oxide? 

Healthy nitric oxide levels are key for your circulation, stamina, and cardiovascular wellness. But nitric oxide is also fleeting. It lasts only seconds in the body. Testing helps you make informed decisions about your diet, activity, and supplementation.

Calroy’s patent-pending dual-pad technology provides a more complete picture of your nitric oxide health by measuring both: 

  • Prebiotic nitrate levels, indicating your dietary intake of nitrate-rich foods 
  • Salivary nitrite biomarkers, reflecting your body’s nitric oxide conversion status 

Together, these readings show your current nitric oxide levels, helping you understand your overall health as well as the health of your oral microbiome.  

Why Test Nitric Oxide? 

Interpreting Your Results

The darker the pink color, the higher your nitric oxide levels. The goal is to be in the dark pink optimal range. Don’t worry if you test low. Most people do. Nitric oxide naturally declines with age, but you can improve your results with lifestyle and nutrition choices that encourage nitric oxide production: 

  • Eat nitrate-rich foods like leafy greens, beets, and celery 
  • Exercise regularly, which helps stimulate nitric oxide production 
  • Support with supplements like Vascanox HP®, providing nitric oxide support for up to 24 hours*† 

Test. Don’t Guess. 
Nitric oxide levels are dynamic, affected by your oral microbiome, diet, stress, age, and physical activity. With Calroy’s 2-in-1 Nitric Oxide Test Strips, you can track those changes and see how daily habits influence your vascular health. 

Quality You Can Trust 

  • Patent-pending dual-pad design for comprehensive nitrate + nitrite testing 
  • Scientifically validated, easy to read results in 10–15 seconds 
  • 50 test strips per canister 

†As measured by saliva NO test strips in an open-label published study.

Frequently Asked Questions

How often should I test?

You can test daily, weekly, or as often as you’d like to see how lifestyle choices affect your nitric oxide levels.

What do these strips measure?

Both oral microbiome health (prebiotic dietary nitrates) and nitric oxide biomarkers (salivary nitrites), givinga comprehensive view of your salivary nitric oxide health.

How soon will I see results?

You’ll get your nitric oxide reading in seconds. Test before and after dietary or supplement changes to track changes in nitric oxide status.

Can I use them with Calroy supplements?

Yes. Use with VascanoxHP® to see sustained nitric oxide effects that supports nitric oxide production at its source.* For foundational vascular support, consider ArterosilHP®.
