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.
Interventions
DIETARY_SUPPLEMENTPhaeosol low dose
1 Phaeosol softgel of 440mg/day and 1 placebo softgel of 500mg/day (look like softgel of Phaeosol product) + 1 capsule of 440mg/day of natural stimulant Subjects were instructed to take the study supplement or placebo once daily for 1 months (±2 days). The first and the last doses will be administered at the clinical site during Visit 2 (Experiment 1) and Visit 3 (Experiment 2, respectively).
DIETARY_SUPPLEMENTPhaeosol high dose
2 Phaeosol softgels of 440mg/day + 1 capsule of 440mg/day of natural stimulant. Subjects were instructed to take the study supplement or placebo once daily for 1 months (±2 days). The first and the last doses will be administered at the clinical site during Visit 2 (Experiment 1) and Visit 3 (Experiment 2, respectively).
DIETARY_SUPPLEMENTPlacebo
2 placebo softgels of 440mg/day (look like softgel of Phaeosol product) + 1 capsule of 500mg/day containing Microcellulose (look like capsule of natural stimulant). Subjects were instructed to take the study supplement or placebo once daily for 1 months (±2 days). The first and the last doses will be administered at the clinical site during Visit 2 (Experiment 1) and Visit 3 (Experiment 2, respectively).
