Nitric Oxide Test Strips by Designs for Health are a simple, at-home way to monitor nitric oxide (NO) levels and support overall cardiovascular, metabolic, and performance health. Nitric oxide plays a key role in circulation, oxygen delivery, endurance, and healthy aging.

These easy-to-use test strips help assess two critical factors involved in nitric oxide production:

1. Intake of nitrate-rich foods or supplements

2. Presence of beneficial oral bacteria that convert nitrates into usable nitric oxide

By testing regularly, you can better understand how your diet, supplements, and lifestyle support nitric oxide production and make adjustments to optimize results.

Key Benefits

• Supports cardiovascular and circulatory health

• Helps monitor nitric oxide bioavailability

• Supports athletic performance and recovery

• Encourages healthy aging and metabolic function

• Simple, fast, and non-invasive testing

• Helps guide dietary and supplement choices

Suggested Use

Test first thing in the morning, then take Vascanox HP® or another nitrate-supporting supplement.
Test again 1–2 hours later to confirm nitric oxide availability.

For ongoing monitoring, testing can be done at least twice daily, or more frequently as needed to assess daily trends.

How It Works

The test strips measure salivary nitrate levels, which reflect the body’s ability to convert dietary nitrates into nitric oxide. Results help determine whether lifestyle or nutritional adjustments may be beneficial for optimal NO production.

Who It’s For

• Individuals supporting heart and vascular health

• Athletes and active individuals focused on performance

• Anyone interested in monitoring nitric oxide status

• Those using nitrate-rich foods or NO-support supplements
