研究概览
简要总结
This is a Phase 1, double blind, randomized, controlled, cross-over trial.
The primary outcome is to quantify the incremental area-under-the-concentration-curve (iAUC) for plasma caffeine after oral consumption of caffeinated beverages with various bioactive compounds vs. caffeine alone, in 16 healthy volunteers
Secondary outcomes are caffeine concentration at each time point from pre-dose baseline to 3.5 hrs post-dose, peak caffeine concentration (Cmax), time to maximum caffeine concentration (Tmax) and return to baseline concentration (TBR) for plasma caffeine
Other outcomes are ratings of physiological symptoms and mood, assessed using visual analog scales (VAS).
Polyphenol food frequency questionnaire data at screening will be collected as a possible co-variate.
