Nutrex NIOX Advanced Review

Manufacturer’s Claim

For body builders and avid gym goers, investing hours at the gym requires hard, persistent effort and who doesn’t want to see their hard work at the gym pay off? Nutrex NIOX Advanced promises to optimize time at the gym by boosting levels of nitric oxide in the bloodstream. Combined with intense training, they promise taking their product will result in rounder, fuller muscles. They further claim that their product will enhance endurance performance.  With so many products available promising similar results, this review examines Nutrex NIOX’s effectiveness and if it is a product in which you will see amplified results at the gym. Because who doesn’t want to see faster and better results?


  • Carnosyn Beta-Alanine
  • Agmatine Sulfate and Agmapure
  • Arginine
  • Glycerin
  • Vegetable Cellulose
  • Purified Water
  • Polysorbate

It was a cause for concern for us that the amounts of each ingredient are not listed on their website and in our research, we were unable to find the amounts listed anywhere online. The key ingredients Carnosyn Beta-Alanine and Agmatine Sulfate and Agmapure are proven to increase the flow of nitric oxide but ultimately we don’t know how much we’re really getting in every dosage.


Nutrex NIOX Advanced recommends taking 3 liquid capsules with 10 oz. of water twice daily, 30 minutes before breakfast and 30 minutes before dinner. On training days, they recommend taking one daily serving 30 minutes before a workout. For optimum results, they advise staying hydrated and taking the capsules every day.

They do not recommend taking if pregnant or nursing.


The cost for one 120 capsule bottle listed on their website is $21.99. While this price doesn’t appear to be costly if taking the recommended 6 capsules a day, one bottle will last only 20 days.

Possible Side Effects

While the website does not list any possible side effects we found complaints online of consumers who had experienced low blood pressure. This puts into question how much research was conducted before putting this product on the market and if research has been done why they would not disclose this information to the consumer.


Nutrex NIOX Advanced offers a 30-day money back return policy for unopened bottles. For opened bottles, there is a 15-day money back guarantee from the point of receiving the product.

Nutrex NIOX Advanced Review – The Bottom Line

From our research, we have found several reviews of satisfied customers who have used Nutrex NIOX Advanced. Its key active ingredients, Carnosyn Beta-Alanine and Agmatine Sulfate and Agmapure are known to increase the flow of nitric oxide in the bloodstream. However, its effectiveness and credibility are put into question with its alarmingly high recommended dosage. Because the amount of each ingredient is not listed on their website or anywhere online, there is no way for us to know if the reason for such a high recommended dosage is simply a ploy to buy more. In our research, we have found similar products available on the market with better guarantees which leads us to further question Nutrex NIOX Advanced’s validity. A combination of its ambiguous list of ingredients and weak money back guarantee policy puts the consumer at risk.
