Newly Published Placebo-Controlled Study Shows Nutrition21's Nitrosigine® Improves Cognitive Performance Following Intense Exercise

Press Release ( - HARRISON, N.Y. - Aug 27, 2020 - A new clinical study yielding exciting results in the field of sports nutrition has been published in the Journal of Exercise and Nutrition (JEN) entitled “Inositol-Stabilized Arginine Silicate Improves Post-Exercise Cognitive Function in Recreationally Active, Healthy Males.” The results of the study showed significant improvements by Nitrosigine in post-exercise cognitive function tests compared to placebo.

Success in athletics does not come down to physical abilities alone, as cognitive factors and mental stamina are also critical to performance. As a leader in sports nutrition, Nutrition21 sponsored this study to further understand the cognitive benefits of a patented complex of inositol-stabilized arginine silicate (ASI; Nitrosigine®) – an ingredient known for its success in the pre-workout market. Nutrition21 had already established in multiple studies the significant cognitive benefits of Nitrosigine when used at rest. The objective of this study was to further the science on this ingredient by studying its ability to improve cognitive performance following intense exercise.

Twenty-four healthy, recreationally active males were enrolled in this randomized, double-blind, placebo-controlled crossover study. A single oral dose of 1500 mg Nitrosigine or placebo was administered 30 minutes before a maximally graded exercise test. Prior to dosing and following exercise, cognitive function was assessed via the Trail Making Test (TMT), which evaluates motor speed and visual attention. Safety was evaluated during and at the end of the study.

The study revealed that acute supplementation with Nitrosigine elicits a significant improvement in cognitive function following intense exercise, which may translate to enhanced athletic performance (as assessed by the TMT). Nitrosigine has the ability to prevent exercise-induced mental fatigue, a factor that could have profound effects on recreational athletes and physically active individuals who suffer from mental fatigue during extended amounts of exercise.

Nitrosigine has 30 research studies for safety and efficacy and has a number of powerful benefits for users:

  •  Nitrosigine works fast- within 15 minutes increasing focus, mental flexibility^, and executive function
  • Improved cognitive flexibility^ by 41% vs. placebo after a single dose
  • Nitrosigine significantly boosts nitric oxide levels, a key factor for increasing blood flow to working muscles
  •  As a non-stimulant, Nitrosigine increases energy both safely and quickly *
  •  Nitrosigine has been shown to boost muscle pump with significant increases in muscle volume
