People complement nitric oxide test strips with the NAD+ pen as monitoring nitric oxide levels helps track vascular health, while NAD+ supports cellular energy and recovery, enhancing overall cardiovascular function and wellness.
Supports testing before workouts or after nitrate-rich foods.
Nitric Oxide Test Strips Tube provides a simple and non-invasive way to measure nitric oxide levels using saliva. Designed for at-home use, the patented test strips deliver immediate colour-based results, allowing you to check levels in less than 10 seconds without any equipment or preparation.
To use, place the strip on the tongue, press the ends together, and compare the colour result. This straightforward process makes the strips suitable for regular monitoring, whether used daily, before physical activity, or after consuming nitrate-rich foods or supplements.
Nitric oxide plays a role in blood flow, circulation, and cellular signalling. Levels can vary due to factors such as age, diet, lifestyle, and oral care habits. Regular testing helps provide insight into nitric oxide status, allowing informed decisions around nutrition and supplementation.
