Nitric Oxide Test Strips

Saliva Test for Nitric Oxide Foods and Probiotics

Saliva test strips designed to help individuals maintain optimal nitric oxide (NO) status for overall wellness, including healthy blood pressure and circulation.

These saliva test strips are non-invasive and easy to use. Plus, actionable results are instant — in just 10 seconds.

These test strips quickly and easily monitor two requirements needed to promote a major pathway of NO production: sufficient intake of NO-supportive supplements or nitrate-rich foods (such as beets and leafy greens), and the presence of oral nitrate-reducing friendly bacteria or probiotics.

Recommended Use: Use at least twice a day (once first thing in the morning and another test 1 to 2 hours after a nitrate-containing supplement or meal). Can be used multiple times a day for hourly or daily monitoring.

This test is not intended to diagnose disease. It detects prebiotic nitrate and the presence of the oral microbiome that begins the process to convert dietary plant-derived nitrate to nitric oxide.

Provides 50 saliva test strips

Nitric Oxide Test Strips by Designs for Health easily monitor prebiotic-nitrate intake and the presence of nitrate-reducing probiotics in your oral microbiome for healthy NO production.
