Caffeine and taurine combo may boost exercise and brain power
NCT ID NCT07466654
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether low doses of caffeine and taurine, taken together, improve anaerobic, neuromuscular, and cognitive performance more than either alone. Thirty-two healthy young men who strength train regularly took part. They received caffeine, taurine, both, or a placebo before testing. The goal was to see if the combination works better than each supplement separately.
