Acute effects of a caffeine-containing, adaptogenic-rich (AD) natural energy beverage, a matched caffeine-containing beverage (CA), and a placebo were assessed toward several neurocognitive measures in a double-blinded, crossover trial. Thirty participants who were low consumers of caffeine without elevated feelings of energy. were subjected to tests measuring motivation, mood, and sustained attention (serial subtractions of 3 and 7, the continuous performance task (CPT), and the Rapid Visual Input Processing task (RVIP)) both prior to and after consumption of each beverage. Heart rate, blood pressure and fine motor skills (9-hole peg test) were also evaluated. Treatment X Time ANOVAs showed that when compared to placebo, CA increased feelings of anger and energy along with a reduction in fatigue. The AD beverage showed an increased number of responses on the serial subtract 3 task when compared to the CA beverage. An ANOVA examining overall changes noted significantly greater decreases in fatigue for the AD beverage compared to the CA beverage. These results suggest that caffeine, when mixed with adaptogens, can improve certain aspects of sustained attention and reduce feelings of fatigue, but had little effect on motivation to perform tasks and feelings of energy. Moreover, the addition of adaptoogenic herbs may also attenuate the anxiety provoking effects of drinking caffeine alone.
