The number 1 element, that a human body needs, is O2. In case of heavy weights and more intensive training your body works hard to maintain blood oxygen levels.

There is a time during physical activity when heavy breathing does not produce enough oxygen. It is when the muscle fatigue achieves you (when the glycogen in Oxygen-starved blood transforms into lactic acid). Here is the main time to bring more oxygen into your body and muscles.

Nitro2 helps to reach your peak performance and recover faster. (By getting more oxygen, the blood is able to inhibit the production of lactic acid and expel any existing already.) Oxygen is the most important nutrient when it comes to athletic performance. It helps to produce ATP and restore it’s levels during recovery. Supplementing with high-purity oxygen is a game-changing factor at the hardest moments.

Nitro2 is 99% pure Oxygen, all-natural and safe.

According to the World Anti-Doping Association (WADA), supplemental Oxygen is not considered a banned substance.
