The study compared two popular ingredients used in sports nutrition today: citrulline malate (CM ) and bonded arginine silicate (Nitrosigine®). Nitrosigine® is a leading branded ingredient used in a variety of consumer products with a legacy of continued success in the sports nutrition and pre-workout arena. Nitrosigine® is added to formulations in order to significantly increase serum arginine and nitric oxide (NO) levels, reduce markers of post-workout muscle damage and increase cognitive processing speed. CM is used for its ability to increase blood serum concentrations of arginine, resulting in NO production.
Dr. Michelle Gray, Associate Professor and the Director of the Exercise Science Research Center at the University of Arkansas, commented "Current research has yet to compare CM and Nitrosigine® in vivo using a flow-mediated dilation (FMD) technique, a validated measure of the vascular endothelium's NO producing ability. We identified a need and designed the experiment with the purpose of determining the effectiveness of Nitrosigine® and CM compared to placebo, in up-regulating NO production in blood vessels as measured by acute changes in vasodilation."
The double-blind, placebo-controlled, crossover design study was performed, with a 7-day washout period between test visits. The subjects were 22 healthy, normotensive, and at least moderately active male (n=14) and female (n=8) young adults.
Results showed that a single dose of 1.5g of Nitrosigine® significantly increased FMD, a measurement of increased vasodilation, blood flow, and possibly nitric oxide levels, more than placebo (p<0.01) and to the same extent as 8g of CM.
Overall Clinical Results of the Study:
"Nutrition 21 was excited to hear of this independent study and the positive results showing the benefits of Nitrosigine® on increasing vasodilation, a process driven by increasing nitric oxide production, and believed to enhance a number of sports performance endpoints. We are especially pleased that this study was designed to test a healthy, athletically trained population, and showed that a 1.5g dose of Nitrosigine® worked as well as 8g of Citrulline Malate, in increasing flow mediated dilation." says James Komorowski, MS, CNS, Chief Science Office at Nutrition 21.
