Nutrition 21 is thrilled to have this additional clinical evidence further supporting the significant long-lasting bioavailable benefits of Nitrosigine.

Nutrition 21, LLC (“Nutrition 21”) is proud to announce the presentation of new clinical study results supporting the bioavailability of Nitrosigine® bonded arginine silicate (ASI), titled, “A Pharmacokinetic Evaluation of the Duration of Effect of Inositol-Stabilized Arginine Silicate and Arginine Hydrochloride in Healthy Adult Males.” The study was presented on April 3rd, 2016 to scientists and other professionals at the acclaimed Experimental Biology 2016 annual meeting and the abstract will be published in the Federation of American Societies for Experimental Biology Journal (FASEB).

The study demonstrated that Nitrosigine® bonded arginine silicate supplementation significantly increased plasma arginine levels at multiple time-points up to six hours, post-dose, while Arginine Hydrochloride (ArgHCl) supplementation did so for only one hour (Figure 1). This study also showed that Nitrosigine supplementation resulted in a >70% increase in plasma arginine levels (area under the curve) compared to Arginine HCl and a lower standard deviation than that seen with Arginine HCl, supporting Nitrosigine as a more bioavailable, long-lasting and less variable, source of arginine.     

James Komorowski, MS, CNS, Vice President, Scientific & Regulatory Affairs of Nutrition 21 commented, “We are extremely pleased with the presentation of these impressive clinical results, showing Nitrosigine supplementation significantly increased plasma arginine levels at multiple time points from baseline at 1, 1.5, 2, 3 and 6 hours (p<0.05), while plasma arginine levels in the Arginine HCl group only increased at 1 hour (p<0.05). These results continue to enhance our knowledge of the positive effects of Nitrosigine in humans.”

“Nutrition 21 is thrilled to have this additional clinical evidence further supporting the significant long-lasting bioavailable benefits of Nitrosigine. Leading sports nutrition companies continue to recognize the unique value of our ingredient Nitrosigine, and formulate it into their workout products. Nitrosigine has been shown to enhance performance to give sport nutrition products a competitive edge. Consumers should look for the Nitrosigine logo on workout products to get more out of their fitness training. We anticipate continued high market interest with robust customer sales,” said Bill Levi, Vice President, Strategy & Business Development at Nutrition 21.

Consumer benefits directly linked to Nitrosigine supplementation have been clinically substantiated, including:

  • Nitrosigine is a safe, bioavailable source of arginine and silicon
  • Nitrosigine significantly enhances blood arginine levels for up to 6 hours^
  • Nitrosigine significantly increases silicon levels for up to 1.5 hours
  • Nitrosigine boosts key factors for increasing blood flow^
  • Nitrosigine increases energy quickly and safely
  • Nitrosigine dramatically improves mental acuity and focus
  • Nitrosigine increases muscle volume^
  • Nitrosigine reduces muscle damage from exercise
