This study will evaluate how a yerba mate caffeine beverage affects energy, alertness, and well-being compared to participants’ usual caffeine intake. Researchers will measure self-reported outcomes such as jitteriness, relaxation, and mood using validated surveys, as well as wearable-tracked sleep and physiological data. The goal is to understand whether yerba mate provides a smoother, more balanced caffeine experience than coffee or energy drinks.
