It is often infused as a drink taken by people. Other sources of caffeine include yerba maté, guarana berries, guayusa, and the yaupon holly.

Post-pubertal Girls and Boys May React to Caffeine Differently

Girls also experience some differences in caffeine effect during their menstrual cycles. This study will be published in the July 2014 edition of the journal Pediatrics. The researchers have found a relationship between gender and caffeine dose, with boys having a greater response to caffeine than girls, as well as interactions between pubertal phase, gender and caffeine dose, with gender differences present in post-pubertal, but not in pre-pubertal, participants.
