Nitric Oxide Ingredient from Fruit Polyphenols

Nexira (Rouen, France) has introduced ViNitrox, a nitric oxide formula made up of apple and grape polyphenols.

Nexira says its synergistic formula can increase nitrix oxide production during exercise by as much as 24%. Other demonstrated benefits include reducing oxidative stress by as much as 74% and increasing vasodilation up to 50%. In a double-blind, placebo-controlled, crossover study on 50 athletes, consuming 500 mg of ViNitrox reportedly extended physical training time by 10% and increased time-to-fatigue by 13%.

ViNitrox is intended for dietary supplement tablets, capsules, and gels.
