Key Benefits
- Fast, simple saliva testing in under 10 seconds.
- Helps establish a personal nitric oxide baseline.
- Useful for daily monitoring and routine tracking.
- Supports testing before workouts or after nitrate-rich foods.
Nitric Oxide Test Strips Tube provides a simple and non-invasive way to measure nitric oxide levels using saliva. Designed for at-home use, the patented test strips deliver immediate colour-based results, allowing you to check levels in less than 10 seconds without any equipment or preparation.
To use, place the strip on the tongue, press the ends together, and compare the colour result. This straightforward process makes the strips suitable for regular monitoring, whether used daily, before physical activity, or after consuming nitrate-rich foods or supplements.
Nitric oxide plays a role in blood flow, circulation, and cellular signalling. Levels can vary due to factors such as age, diet, lifestyle, and oral care habits. Regular testing helps provide insight into nitric oxide status, allowing informed decisions around nutrition and supplementation.

The best wellbeing website…
The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Amazing!
Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!

Great products, service, and customer support
Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf
It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
