PURCHASE, NEW YORK – April 30, 2014 – Nutrition 21, LLC (“Nutrition 21”) ”) is proud to announce the presentation of new clinical study results supporting Nitrosigine™ inositol-stabilized arginine silicate, titled, “A Clinical Evaluation to Determine the Safety, Pharmacokinetics and Pharmacodynamics of an Inositol-Stabilized Arginine Silicate Dietary Supplement in Healthy Adult Males.” The study will be presented today to scientists and other professionals at the acclaimed Experimental Biology 2014 annual meeting’s poster session and will be published in the Federation of American Societies for Experimental Biology Journal (FASEB).

The clinical study demonstrated significant increases in plasma arginine levels (P<0.01) and serum silicon levels (P<0.01) after a single dose of Nitrosigine™. In addition, a significant increase in nitric oxide levels (measured as salivary nitrites) was seen after 14 days of product consumption (P<0.05). The results of the clinical study support the use of Nitrosigine™ as a bioavailable source of arginine and silicon, validating the preclinical studies and confirming Nitrosigine™ as an effective ingredient in products for sports nutrition, men’s health and cardiovascular health.


Nitric Oxide Levels Clinical Evaluation Results

NO was measured using salivary test strips in a 10 subject clinical study, using a color scale for “Depleted”, “Low”, and “Normal” levels.


NO levels were measured in each study subject before, and at a number of time points after, administration of ASI as a single dose and after 14 days of daily dosing.


Primary author, Douglas S. Kalman, PhD, RD, CCRC, FACN, Director BD, Nutrition & Applied Clinical Trials at Miami Research Associates stated, “Nitrosigine, a new FDA-approved arginine-based molecule, has early and preliminary research that is deserving of further development.”

James Komorowski, MS, CNS, Vice President, Scientific & Regulatory Affairs of Nutrition 21 commented, “We are immensely pleased with the new clinical results. The clinical study confirms our pre-clinical work, and supports Nitrosigine’s™ ability to optimize the benefits of rigorous workouts by significantly increasing nitric oxide levels. Fitness-focused customers who want to get the most out of their training regimen, will appreciate that Nitrosigine™ is quickly absorbed by the body, taking effect in 30 minutes and lasting up to three hours. Nitrosigine™ has also been shown to significantly raise arginine and silicon levels – both important nutrients for cardiovascular performance.”

Consumer benefits directly linked to the clinical study findings include:
• Nitrosigine™ significantly enhances nitric oxide levels
• Nitrosigine™ is a safe, bioavailable source of arginine and silicon
• Nitrosigine™ significantly increases plasma arginine levels in 30 minutes
• Nitrosigine™ significantly increases plasma arginine levels for up to 3 hours
• Nitrosigine™ significantly increases silicon levels for up to 1.5 hours

“Nutrition 21 is thrilled to have the human clinical study available as support for our NDI-accepted, Nitrosigine™. Based on clinical and pre-clinical results, Nitrosigine™ demonstrates superiority over arginine as shown by increases in blood flow markers and silicon absorption. Nitrosigine™ is currently available in the retail channel in products such as, SuperPump® 3.0 and Razor8® and is in development in other finished goods. We anticipate continued high market interest with robust customer sales,” said Jim Kahn, Executive Director of National Sales at Nutrition 21.
