What benefits are there of taking a nitric oxide supplement?

Nitocoxide: It is supposed to enhance relaxation of blodvesslels , decrease choleterol levels and enhance muscele function.

Probably none: I have seen conflicting studies. Many suggest that it is arginine which may be included as a supplement that releases a small amt of nitric oxide. Which may increase endurance. Seen other studies that say eating nitrates for breakfast may raise levels later in the day.
