Setria Performance Blend—a novel combination of L-citrulline and glutathione—may enhance the synthesis, bioavailability, and bio-efficacy of nitric oxide for athletes.
 
That’s the message Stephen Bailey, PhD, gave to attendees at last week’s Nutrition in Athlete Development Summit in Madrid. Dr. Bailey was one of several experts who discussed best practices and latest innovative approaches in sports nutrition for professional athletes, coaches, sport club officials, and producers of sports nutrition and supplements.
 
Studies have shown that Kyowa’s Setria Performance Blend supports nitric oxide production and sustains nitric oxide levels in the bloodstream. In addition, Setria Glutathione, which is the body’s most important antioxidant, allows for longer workouts by increasing time to fatigue while protecting muscle cells from free radicals and oxidants.
 
In his presentation, Dr. Bailey showed that increasing NO has a positive impact on several biological functions that extend well beyond vasodilation, such as skeletal muscle metabolism and force production during exercise.
 
“Oral L-citrulline supplementation is more effective than the same dose of orally ingested L-arginine at increasing circulating and tissue L-arginine content,” Dr. Bailey said. “Adding GSH [in the form of Setria Performance Blend] as a non-enzymatic antioxidant to help neutralize reactive oxygen species (ROS) may sustain the biological effects of NO.
 
Setria Performance Blend is manufactured by Kyowa Hakko Bio, a sponsor of the Nutrition in Athlete Development Summit.
