Abstract: NeuroDrinks® are beverages designed to enhance certain aspects of consumers’ lives, such as sleep, attention, or mood. The NeuroBliss® beverage is marketed as a product that helps reduce stress, enhance mood, provide focus and concentration, and promote a positive outlook (drinkneuro.com/bliss). NeuroBliss® contains some anxiolytic and memory boosting ingredients, such as L-theanine, chamomile, Alpha GPC and Vitamin D. We tested the impact of NeuroBliss® consumption on measures of mood, memory, and anxiety in undergraduate students. After a mood pre-assessment test, undergraduate students consumed either one bottle of the original NeuroBliss® blend (n=14) or a placebo (n=16). Participants then attended a college level biology class and took a mood post-assessment test and a memory test approximately three hours later. Statistical analysis using both paired and unpaired t-tests indicated that NeuroBliss® had no significant effects on anxiety levels, mood, or memory. The results indicate that NeuroBliss® did not provide the advertised effects in an undergraduate population. Future studies could determine the effects of the other NeuroDrink® line of beverages.
