Gaming performance — accuracy and reaction time
The first ever clinical study on gamers (double-blind, placebo-controlled) confirmed nooLVL® significantly improved gaming accuracy, reduced error rates, and improved reaction time vs. placebo during extended gaming sessions. A second study confirmed these benefits specifically in esports scenarios — making nooLVL® the most rigorously studied cognitive ingredient for gaming applications.
Non-stimulant focus and mental clarity
nooLVL® improves cognitive performance through NO-mediated cerebral blood flow enhancement rather than stimulant receptor activation — providing clean focus and mental clarity without caffeine's anxiety, jitteriness, or crash. This non-stimulant mechanism allows all-day use and combination with caffeine for enhanced effects.
Brain health and neuroprotection
Inositol (a key component of nooLVL®) plays essential roles in neuronal cell membrane integrity, neurotransmitter signaling (serotonin, dopamine), and the phosphatidylinositol second messenger system. Regular inositol supplementation supports brain health beyond acute cognitive performance, particularly relevant for the brain health positioning that Nutrition21 has expanded nooLVL® into.
Cerebral NO production and inositol neuronal support
Arginine from nooLVL® serves as the direct substrate for endothelial NOS (eNOS) — producing nitric oxide that dilates cerebral blood vessels, improving oxygen and glucose delivery to active brain regions. The inositol stabilization in nooLVL® ensures superior arginine bioavailability vs. standard L-arginine (which is poorly absorbed orally). Inositol itself supports phosphatidylinositol synthesis in neuronal membranes and modulates serotonin and dopamine receptor sensitivity — providing direct neuronal cognitive support complementary to the vascular NO mechanism.
Randomized, double-blind, placebo-controlled crossover study of nooLVL® (1,600 mg) effects on gaming accuracy, reaction time, and cognitive performance in actual gamers playing modern video games.
Gamers. Double-blind crossover with actual gaming performance assessment.
nooLVL® significantly improved gaming accuracy, reduced error rates, and improved reaction time vs. placebo within 15 minutes of ingestion. First ever clinical study specifically designed for and conducted on gamers using real gaming scenarios. Supports nooLVL® as the evidence-based gaming supplement ingredient.
