Calroy’s 2-in-1 Nitric Oxide Test Strips are quick, affordable, and scientifically validated. Measuring your nitric oxide levels offers valuable health and wellness insights. You can then make informed decisions and take steps to optimize healthy nitric oxide production.

With its patent-pending dual-pad testing, Calroy’s 2-in-1 Nitric Oxide Test Strips measure both:

• Prebiotic diet by measuring prebiotic nitrate levels
• Nitric oxide through salivary nitrite biomarkers

Test in just 10-15 seconds. Each canister contains 50 easy-to-use strips.

Test yourself to get a baseline before making any changes. Then test at 2 and 24 hours after taking Vascanox HP to track changes in nitric oxide levels.

1. Collect saliva from the tongue where "saliva here" is marked. Hold for 5 seconds.
2. Fold the strips over and gently press the two sides together. Gently hold both pads together for 10 seconds.
3. Separate and compare the colour of the test pad to the NO scale.
