• Amp up Nitric Oxide level
  • Improves muscle performance and break through the fatigue barrier
  • Powerful antioxydant

ViNitrox TM is a unique proprietary synergistic combination of apple and grape polyphenols. ViNitrox TM  is the result of the association of a unique “terroir” expertise and a specific process to meet with specific athletes demands, looking for natural dietary supplements.


Nexira’s Grape Extracts are mainly sourced from famous French vineyards and are carefully harvested and selected to offer the highest content in phenolic compounds. Active ingredients are extracted from seed, leaf, skin and shoot as each part of the vineyard is unique.

Nexira draws its know-how from its exceptional French heritage to offer the best combination of grapes and apples supported by a clinical study.

Healthy blood flow is linked to production of Nitric Oxide (NO) by an enzyme called eNOs (endothelial Nitric Oxyde synthase). In vitro1 and ex vivo2 studies show that Vinitrox TM increases eNOs activation by 43% and NO production by 24%.

The latest clinical study of Nexira was conducted on 50 athletes aged from 25 to 451. Results shows that athletes who took 500 mg per day of ViNitroxTM and making an intense effort, improve physical capacities:

  • Increases physical training time by 10%
  • Optimized physical capacities by delaying the fatigue barrier by 13%

It offers outstanding properties on sports nutrition, especially with an effect on performance improvement and an extension of the effort duration. An in vivo study shows protective properties3:

  • A decrease of 74% of oxidative stress
  • A minimum guaranteed ORAC value 6000µmol TEq/g

Moreover, similar conclusions were observed during the two new consumer studies4 (running contest and working out sessions):
70% agree that ViNitrox™ reduces muscle fatigue and cardio-respiratory fatigue
ViNitrox™ increased individual power during “Clean” exercise from the first intake.

Manufactured in France, ViNitroxTM is a nutraceutical ingredient easy-to-use in tablets, capsules, gels, shots etc..
