Citicoline Dose on Energy Drink Efficacy

The purpose of this study is to determine how the doses of cognitive-enhancing ingredients such as citicoline and caffeine effect the efficacy of acute energy drink consumption for improving cognitive performance (primary outcome), gaming performance, mood, energy expenditure, and fat oxidation. This study will utilize an In vivo acute response, randomized, double-blind, placebo controlled, cross-over trial study design. Participants will complete consent, complete screening, and then undergo familiarization and complete four experimental study visits. In brief, participants will consume a commercially available energy drink specifically formulated to improve cognitive performance with the standard dose of Cognizin, a reduced dose of Cognizin, a reduced dose of caffeine and Cognizin, or a placebo (water, which will be carbonated, matched for flavor, mouthfeel, etc.), then complete a battery of computer-based cognitive performance test, tasks in a video game (Tetris) to assess video game performance, have their resting metabolism analyzed, and then assessments of mood. Following a 1-week washout period, participants will return and consume one of the four remaining beverages and complete the same tasks. They will participate in four experimental visits, each time consuming a different beverage until they have consumed all beverages and completed all necessary tasks. Question(s) and Hypotheses (stated in null) Q: Does acute consumption of a new formulations (reduced active ingredients \[citicoline and caffeine\]) of a commercially available energy drink elicit similar improvements in cognitive performance, mood, energy expenditure and fat oxidation in young adults than the standard, currently marketed dose to formulation? H1: Acute consumption of the commercially available energy drink with standard dosing will improve cognitive performance compared to the reduced dose beverages and the placebo. H2: Acute consumption of the commercially available energy drink with
