Results

METHODS: A crossover RCT was conducted in 58 healthy Japanese men. Participants consumed either a test coffee chlorogenic acids (116.9 mg/d) or a placebo for 12-day with a 1- to 2-week washout periods. The primary outcome was a VAS for fatigue. RESULTS: 57 completed the study and were included in FAS. The LS mean difference in VAS for fatigue between the coffee chlorogenic acids and placebo was -7.4 mm (95% CI: -13.1 to -1.7, p = 0.012) at week 1, and -2.0 mm (95% CI: -8.7 to 4.7, p = 0.551) in week 2.
