NO2 Red is a nitric oxide booster, which looks more like an arginine supplement with a ton of vitamins thrown in for good measure. All nitric oxide boosters contain at least one form of arginine. Arginine works to promote nitric oxide production and function naturally, so why not supplement it to boost natural functions? Arginine and other ingredients used in NO2 Red are trusted in the bodybuilding community, so there is no need to offer clinical research supporting these ingredients. We notice a statement at the bottom of the product label that explains what the company truly believes the supplement will do for the user. According to the statement, “Ingredients in NO2 Red help promote exercise recovery and balance healthy homocysteine levels.” That statement says nothing about nitric oxide production and support.

Product Features

There are a few problems with the label description for NO2 Red that clearly negate the claims made by MRI. First, the six phase process explained as the core function of the supplement is nothing more than an explanation of how the ingredients in the supplement work in the body. We could use the same process to explain how water works in the body and tack it onto the side of a water glass, but drinking that water is not going to improve the processes.

Next is the statement clinically tested. We are unsure what the company means by clinically tested, but it clearly does not mean clinically proven. The ingredients are likely tested for safety in the lab and nothing more. There is mention of in vitro (lab) testing that shows potential for increasing nitric oxide. However, lab tests are not the same as human tests because there is no way to replicate the body processes that occur after the supplement is taken in a lab setting without humans being involved.

  • MRI lists all ingredients in NO2 Red.
  • Arginine is trusted in the bodybuilding community.


  • The formula is not clinically proven.
  • The six phases do nothing more than explain how the ingredients naturally work in the body.
  • The label states the product may help – not will help.


NO2 Red is not a proven supplement and the ingredient list is redundant compared to other NO supplements. MRI does not have the secret weapon for muscle growth and recovery in NO2 Red.
