What You Should Know
NOx Edge is a chewable tablet taken before a workout to increase nitric oxide levels. This means the supplement is for bodybuilders, not typical dieters working out for weight loss. NOx Edge will not increase metabolism, boost weight loss or curb appetite. What it may do is help the bodybuilder feel stronger muscle pumps in the gym. The supplement is sold through GNC, General Nutrition Center and other online retailers. The pre-workout tablet is one of the few chewable supplements on the market. Chewable supplements dissolve completely in the mouth, allowing for faster absorption and quicker muscle response.
List of Ingredients
Caffeine Anhydrous Microencapsulated, Citrus Aurantium Extract.
Proprietary Creatine Blend: L-Isoleucine, L-Valine, Taurine, MCT Oil, L-Arginine Pyroglutamate, Alpha Lipoic Acid, L-Arginine Alpha Ketoglutarate, L-Citrulline, Beta-Alanine, L-Leucine, Creatine Monohydrate, Creatine AKG Dicreatine Malate, L-Ornithine AKG, Tribulus Terrestris Extract and Guarana Extract.
Caffeine, citrus aurantium and guarana are stimulants. Stimulants are commonly included in weight loss and bodybuilding supplements to increase energy and metabolism. There is a fine line between healthy supplementation with stimulants and overstimulation. NOx Edge includes an unhealthy amount of stimulants. With 200 mg of caffeine, this supplement has the same amount of caffeine as “No Sleep” pills on the market. Add in the stimulating effects of guarana and citrus aurantium and the bodybuilder is likely to feel a good case of the jitters soon after chewing the tablet.
Citrus aurantium is of particular concern. The ingredient is a source of synephrine, the cousin of Ephedra. While synephrine is still legal in the United States, the ingredient has some of the same negative side effects of Ephedra and thus should be taken with caution.
The remaining ingredients are nothing more than amino acids, medium chain triglycerides and creatine. Tribulus terrestris is commonly associated with testosterone boosting supplements, but there are no clinical trials supporting the claims that this natural ingredient boosts testosterone at all.
NOx Edge sells for $41.99.

NOx Edge is more of a stimulant than nitric oxide booster. The supplement may give the user an energy edge, but none of the ingredients are particularly noted as nitric oxide boosters. Users must be wary of taking too many stimulants as they can cause negative side effects. Unless the user is used to taking high levels of caffeine, it is likely they will feel jitters and shakes, especially since the tablet is chewable.
