The Effect of α-GPC on Cognitive Function and Sports Performance

Sponsor: Nanjing Nutrabuilding Bio-tech Co., Ltd.

View on ClinicalTrials.gov

Summary

The goal of this clinical trial is to find out whether daily supplementation with Alpha-Glycerophosphocholine (α-GPC) can improve cognitive function and sports performance in healthy adults. It will also assess the safety and tolerability of α-GPC when taken over a 6-week period. The main questions this study aims to answer are: Does taking α-GPC every day improve cognitive performance on tests such as the Stroop Test, Go/No-go Test, Sustained Attention to Response Task (SART), and Digit-Symbol Substitution Test (DSST)? Does α-GPC enhance upper and lower body sports performance? Does α-GPC positively affect perceived mood, energy, and motivation? Is α-GPC safe and well tolerated compared to a placebo? Researchers will compare α-GPC (350 mg per day) to a placebo (an inactive substance that looks the same) in a randomized, double-blind study. Neither the participants nor the researchers will know who receives α-GPC or the placebo. Participants will: Be randomly assigned to take either α-GPC or placebo capsules once daily for 6 weeks Attend 3 study visits over an 8-week period at Atlantia Clinical Trials in Cork, Ireland Complete cognitive and physical performance tests both acutely (shortly after a single dose) and after 6 weeks of daily use Have their vital signs, body weight, and any adverse events monitored throughout the study Record their diet and well-being during the study period This study will include 80 healthy adults aged 25-55 years who regularly engage in physical activity. The results will help determine whether α-GPC has benefits for brain function and physical performance, and whether it is safe for long-term use.
