Randomized Prospective Double-Blind Studies to Evaluate the Cognitive Effects of Inositol-Stabilized Arginine Silicate in Healthy Physically Active Adults.

 

Inositol-stabilized arginine silicate (ASI; Nitrosigine®) has been validated to increase levels of arginine, silicon and nitric oxide production. To evaluate potential enhancement of mental focus and clarity, ASI (1500 mg/day) was tested in two double-blind placebo-controlled crossover (DBPC-X) studies using the Trail Making Test (TMT, Parts A and B). In the two studies, healthy males took ASI for 14 and 3 days, respectively. In the first study, after 14 days of dosing, TMT B time decreased significantly from baseline (28% improvement, p = 0.045). In the second study evaluating shorter-term effects, TMT B time decreased significantly compared to placebo (33% improvement, p = 0.024) in a 10-min period. After 3 days of dosing, TMT B time significantly decreased from baseline scores (35% improvement, p < 0.001). These findings show that ASI significantly improved the ability to perform complex cognitive tests requiring mental flexibility, processing speed and executive functioning.

This seems like an awesome nootropic and it is very easy to get, but a little pricey. What could be the mechanism of action? Can we reach similar results with Citrulline plus Soy Lecithin?

Maybe, the function of the silicate is to allow the arginine to cross the blood-brain barrier.
