Ultimate fitness partner
Say goodbye to guesswork and hello to precision with NNOXX One. This revolutionary wearable device is the first of its kind to measure both nitric oxide (NO) and muscle oxygenation (SmO2) levels non-invasively.
Real-time data
With NNOXX One, you get real-time data and actionable insights to optimize your performance and achieve your fitness goals faster.
Key performance indicators
These metrics are key indicators of blood flow, oxygen delivery, and overall fitness.
Why Nitric Oxide?
The NNOXX platform monitors your nitric oxide (NO) and muscle oxygen (SmO2) levels. Nitric oxide is the body’s natural regulator of blood flow and oxygen delivery to the brain, heart, and muscles.
Nitric oxide is a measure of your fitness and performance capacity. The higher your NO level, the better you blood flow and oxygen delivery to brain, heart, and exercising muscles

How does NNOXX work?

1
Using patent pending biosensors, NNOXX One shines tissue-penetrating light into the body and measures the amount of oxygen and nitric oxide.
2
The NNOXX One app takes the information, displays it in real-time, and uses it to determine how effective and efficient your workout is.
3
The app can also provide instructions for increasing nitric oxide levels while you're exercising.
The experts love it
See what our lovely customers say about NNOXX Wearable.
I've really enjoyed the NNOXX One so far, I think there is a ton of potential value here!
NNOXX's device and platform were much more developed and responsive compared to other systems I have used in this industry. The continuing education being put out by NNOXX is extremely useful and by far some of the best content in the space.
This non-invasive wearable gives us the opportunity to measure nitric oxide concentrations in our athletes, which, in turn, can give us data and recommendations on programming our training to improve our athlete's performance based on their individual performance markers.
Exercise is good. Effective and efficient exercise is better. NNOXX unlocks better.
NNOXX is the first platform that gives the holistic picture inside your working muscles with real-time measurements of exercise effectiveness and efficiency. No more guessing about how long or how much exercise is needed. NNOXX gives clarity into every workout, every time.
