Quickly check your Nitric Oxide levels with Berkeley Life's patented, non-invasive nitric Oxide saliva test strips. Perfect for daily use, these strips help establish a baseline, track levels before workouts, and monitor after nitrate-rich meals or supplements.

You can test at any time during the day to check your NO levels. Ensure you have not consumed anything 10 minutes prior to testing. Allow a minimum of 1 to 2 hours after your nitrate high meal or supplement before testing.

1. It's simple, 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.
4. Download the Berkeley Test app to get your reading and to track over time.
