Product Information

Patented Berkeley Test Strips are a non-invasive saliva test which allow you to check your Nitric Oxide (NO) levels in seconds. By tracking your saliva nitric oxide status with Berkeley Test Nitric Oxide Saliva Test Strips you can make real-time dietary lifestyle adjustments.

You can test at any time during the day to check your NO levels. It’s simple, place the test strips with the “saliva here’ side on your tongue and compare the color against the NO scale.


Test before and two hours after your nitrate high meal or supplements. Ensure you have not consumed anything 10 minutes prior to testing.


  • 1. Place the test strip with the ‘saliva here’ side on your tongue.
  • 2. Fold the strip over and gently press the two sides together.
  • 3. Now simply separate and compare the color on the test pad to the NO scale.
