How Does Jacked Factory Essentials Nitric Oxide Work?
Jacked Factory Essentials Nitric Oxide is designed to improve blood flow, enhance energy levels, and support muscle performance. Its key ingredient, Nitrosigine, is a patented blend of arginine and silicon that is known to boost nitric oxide levels in the body.
Nitric oxide helps to relax blood vessels and improve circulation. Improved blood flow allows the muscles to receive more oxygen and nutrients during exercise. This results in better pumps, enhanced endurance, and quicker recovery.
Studies suggest that Nitrosigine supplementation increases exercise blood flow and decreases biomarkers of muscle fatigue after exercise. Although Nitrosigine has research supporting its role in improving nitric oxide levels and workout performance, individual results can vary.
Jacked Factory Essentials Nitric Oxide Ingredients: Are They Safe & Effective?
The key ingredients used in making this formula include:
Nitrosigine
Nitrosigine is the key ingredient in Jacked Factory Essentials Nitric Oxide. It is a patented blend of arginine and silicon known to increase nitric oxide levels in the body. Nitric oxide relaxes blood vessels, improving circulation and enhancing oxygen and nutrient delivery to muscles.
Our Niagara XL Reviews (another supplement containing this ingredient) show that it stimulates levels of nitric oxide in the body, which may improve circulation and decrease blood pressure. A study in the Journal of the International Society of Sports Nutrition highlights that Nitrosigine may improve exercise performance, muscle recovery, and cognitive focus after supplementation.
Rood-Ojalvo, S., Sandler, D., Veledar, E. et al, mentioned that
Daily doses of Nitrosigine prior to workout significantly increases pre-workout energy levels, increases muscle pump immediately following a workout, and decreases biomarkers of muscle damage immediately after a workout

Do not know what it is, but after taking L-Arginine N.O. Booster, my legs were sore as heck. Did not see any real benefit. Probably because I stopped using it after 2 days of my legs cramping up. Could hardly walk!!!

The first time and the three other times I took the L Arginine, I had no energy at all. This product does not do as the manufacturer describes. Not at all
