Efficacy of a Microalgae Extract PhaeoSOL Combined With Natural Stimulant on Cognitive Function and Gaming Performance of Video Gamers

Study Overview
=================
Brief Summary
-----------------
Considering the important growing development of gaming in the world, this research area has developed considerably over the last few years. Even if it seems to be well admitted that video gamers showed better cognitive functions (e.g. visual selective attention, cognitive flexibility, task switching) parameters compared to non video gamers there is a constant concern for optimizing performance as for all other kind of athletes. However to our knowledge, only one randomized controlled trial have investigated the potential benefits of dietary supplementation on cognitive function and performance in video gamers. The use of microalgea as molecule of interest sources is a recent promising approach also to meet societal challenge as the maintain of biodiversity/landscape. Thus, the purpose of this study is to examine whether acute (single-dose) and chronic (1 month) supplementation of Microphyt's phaeosol ingredients (BrainPhyt) ingested with or without a natural stimulant, would affect cognitive function and gaming performance in experienced video gamers.
