Investigation on the Chronic Effects of Nepalese Pepper (Zanthoxylum Armatum DC) on Cognitive Function, Mood and Gaming Performance in Young, Healthy, Action Video Gamers

The goal of this clinical trial is to learn if daily supplementation with a Nepalese Pepper Extract (Zanthoxylum Armatum, ZA) can improve cognitive performance and gaming performance in action video gamers aged 16 to 39, when taken over an extended period. The main questions it aims to answer are: Does chronic (42-day) daily ZA supplementation improve speed of cognitive performance and reduce subjective mental fatigue? Do these effects translate into objective and self-reported improvements in gaming performance? Are there additional acute (within-session) effects at the end of a chronic supplementation period, on top of any chronic effect? Researchers will compare 275mg daily ZA supplementation to placebo to see if chronic ZA produces better cognitive performance and lower fatigue than placebo. Participants will: Complete a screening call and a training visit on the computerised cognitive tasks and gaming tasks Take a daily capsule (either ZA or placebo, depending on treatment order) each morning with food for 42 days, then switch to the other treatment for a further 42 days after a 2-week washout Attend four testing visits at the research centre: a baseline and an endpoint visit for each 42-day treatment period Avoid alcohol and energy drinks for 24 hours before each testing visit, and caffeine from waking Complete cognitive tests before dosing and 1 hour after dosing at each testing visit Complete mood and sleep questionnaires Wear a heart rate monitor at rest on arrival at each visit Complete gaming-specific tasks (aim training, MOBA character control, multi-tasking, finger tapping, Fitts' Law, multiple object tracking, collision prediction) Play their action video game of choice at home throughout each 42-day period and complete performance questionnaires

Investigation of the Acute Effects of Nepalese Pepper Extract (Zanthoxylum Armatum DC) on Cognitive Function, Mood and Gaming Performance in Young, Healthy, Competitive Gamers

The goal of this clinical trial is to learn if a Nepalese Pepper Extract (Zanthoxlum Armatum, ZA) supplement can improve cognitive performance and mental abilities in competitive gamers aged 16 to 34. The main questions it aims to answer are: 1. Does ZA supplement improve cognitive abilities like attention, memory, and decision-making? 2. What is the most effective dose of ZA supplement (300mg vs 150mg)? 3. How do the effects of ZA supplement compare to caffeine? Researchers will compare four different treatments (high-dose ZA, low-dose ZA, caffeine, and placebo) to see if ZA supplement produces better cognitive performance than placebo and how it compares to caffeine\*\*. Participants will: * Complete a screening visit with health checks and training on computer tasks * Attend four testing visits (7-14 days apart) where they receive different treatments * Avoid alcohol and energy drinks for 24 hours before each visit, and caffeine from waking * Take assigned treatment at 11:30am and complete cognitive tests at -1, 1, 3, and 5 hours in relation to dose. * Complete mood questionnaires, sleep assessments, and gaming-specific tasks (aim training, character control) * Wear heart rate monitors during testing * Eat standardized meals provided during visits * Play competitive games at home in the evening and complete performance questionnaires

Dose-Response Effect of Phosphatidylserine on eSport Performance

This study will evaluate the effects of daily phosphatidylserine supplementation on electronic gaming performance, cognitive function, sleep quality, stress-related outcomes, and autonomic responses in healthy adult gamers. Participants will be enrolled in a randomized, double-blind, placebo-controlled, parallel-group study and assigned to receive placebo, 100 mg phosphatidylserine, or 200 mg phosphatidylserine daily for 6 weeks. Outcome measures will be assessed at baseline, Week 3, and Week 6 and will include electronic gaming performance, cognitive function, visual analog scale ratings, sleep quality questionnaires, hemodynamic responses, and heart rate variability. The study is designed to determine whether daily phosphatidylserine supplementation can improve performance and selected physiological and psychological outcomes during prolonged electronic gaming sessions.

Effects of Paraxanthine Supplementation on eSport Performancre

This study will evaluate the effects of daily paraxanthine supplementation on electronic gaming performance, cognitive function, sleep quality, and autonomic responses in healthy adult gamers. Participants will be enrolled in a randomized, double-blind, placebo-controlled, parallel-group study and assigned to receive either paraxanthine or placebo daily for 6 weeks. Outcome measures will be assessed at baseline, Week 3, and Week 6 and will include electronic gaming performance, cognitive function, visual analog scale ratings, sleep quality questionnaires, hemodynamic responses, and heart rate variability. The study is designed to determine whether paraxanthine supplementation improves performance and selected physiological and psychological outcomes during prolonged electronic gaming sessions.
