The double-blind, crossover, placebo-controlled study,published in Nutrients,observed 16 participants between the ages of 18 and 28 years old during two separate three-hour trials. The participants sat through three cognitive tests, with results recorded both before and after consuming 1.5g of Nitrosigine + 8g dextrose or a placebo in the form of 8g dextrose. 7 days later, a second trial took place.
The findings: Immediate memory performance in the Nitrosigine group significantly improved compared to the placebo group between trials, with an increase of 27%; delayed memory scores also improved.
