Our Nitric Oxide Indicator Strips, developed at the University of Texas Health Science Center, capture a simple, and non-invasive, saliva sample to determine the concentration of a salivary nitrite, a key biomarker, needed for the production and availability of Nitric Oxide. The concentration of the salivary nitrite, revealed through your saliva sample and collected on our nitric oxide indicator strips, help you understand your body’s NO production levels. 

Suggested Use: Wash your hands and gather saliva on fingertips.  Place saliva on indicator strip pad.  DO NOT PUT STRIP IN YOUR MOUTH.  Compare results with the color chart.
