Instant insight into your nitric oxide levels.

• See your nitric oxide status in real time—anytime, anywhere.

• Check how your oral microbiome may influence your NO levels.

Stay in tune with your body using these quick and simple saliva test strips from Designs For Health. In just seconds, you’ll know your nitric oxide (NO) status—helping you make informed choices about your diet and lifestyle.

Nitric oxide is naturally produced in the body and plays a role in circulation and cell signalling. Your levels can shift depending on what you eat and the balance of your oral microbiome. These strips help you see if you’re getting enough nitrate-rich foods, like beetroot and leafy greens, or if your routine could use a tweak.

With instant feedback, you can adjust your food and supplement choices to help maintain healthy nitric oxide levels every day.

Start your day by testing first thing in the morning, then take Designs for Health’s Vascanox HP®. Test again one to two hours later to see how your nitric oxide (NO) status responds. You can also try Designs for Health’s NOx Synergy™, which provides amino acid precursors for nitric oxide production.

NUMBER OF TIMES PER DAY: At least twice daily—once in the morning and again one to two hours after a nitrate-rich meal or supplement. Feel free to use the strips more often for regular monitoring.
