What are nitric oxide test strips and how do they work?

Nitric oxide is essential for healthy blood flow, energy, brain function, and heart health. Low levels are common, especially after age 40 or with stress, poor diet, or prescription mouthwash use. Testing helps you understand when your body needs support—so you can adjust your nutrition or supplement routine.
