Acute Dose-ranging Effects of Mango Leaf Extract (Zynamite® 15%) on Cognitive Function and Cerebral Blood Flow

Zynamite® is a novel mango (Mangifera indica) leaf extract standardized to contain polyphenol mangiferin.It has previously been shown to enhance brain oxygenation, physical performance and ergogenic parameters following ischemia-reperfusion in healthy humans when consumed alongside other polyphenols. Preliminary data has also indicated that a single 300mg dose of Zynamite® (60%) can improve performance across a range of cognitive tasks.This study aims to evaluate the effects, in healthy adults, of 3 doses of Zynamite® 15% on performance across a number of cognitive domains, as well as during a period of cognitively demanding task performance. A second sub-study will assess cerebral blood flow during cognitively demanding task performance.
