Summary
This study looked at whether a supplement called MIB-626 (a form of vitamin B3) could improve physical performance in healthy, highly fit adults aged 19 to 40. Some participants also did a high-intensity exercise program. The goal was to measure changes in aerobic capacity and endurance. Since participants were already healthy and fit, this study aimed to gather knowledge rather than treat a disease.
