Berkeley Life
Nitric Oxide Test Strips
In just seconds, Berkeley Life’s patented, non-invasive, Nitric Oxide saliva test strips indicate salivary nitrite levels, which are a proven precursor to Nitric Oxide levels in the body. Each tube includes 50 strips.
How to Use
Berkeley Life Nitric Oxide Saliva Test Strips were specifically designed to indicate salivary nitrite levels, a proven precursor to Nitric Oxide levels in the body. Use before and after a nitrate rich meal or supplement.
1. Place the test strip with the “saliva here” side on your tongue and hold for 5 seconds.
2. Fold the strip over and gently press the two sides together and hold for 10 seconds.
3. Separate and compare your results using the Berkeley Test Nitric Oxide Scale on the side of the package.

Quickly and easily assess your Nitric Oxide levels as you track progress.
Regularly assessing your Nitric Oxide (NO) levels can help you track your success with the Berkeley Life Nitric Oxide Foundation supplement, and gauge progress toward your health goals. If you are taking in adequate levels of dietary nitrate and your body is converting it to Nitric Oxide, you will see results on the Berkeley Life test strip.
