Caffeine is an attention enhancer
By David Liu, PHD
Sunday March 3, 2013 (foodconsumer.org) -- Caffeine, which is found in tea and coffee, is an attention enhancer, according to a review recently published in Psychopharmacology.
Einöther SJ and Giesbrecht T from Unilever R&D Vlaardingen inVlaardingen, The Netherlands and colleagues reviewed trials and found "caffeine improves performance on simple and complex attention tasks, and affects the alerting, and executive control networks."
Additionally, the researchers also found "there is inconclusive evidence on dose-related performance effects of caffeine, or the influence of habitual caffeine consumption on the performance effects of caffeine."
The review was based on double-blind placebo controlled studies that assessed acute effects of caffeine on attention in healthy adults.
The authors concluded "Evidence shows that caffeine has clear beneficial effects on attention, and that the effects are even more widespread than previously assumed."
Caffeine is a dietary supplement that can be purchased from online stores. Caffeine is a stimulant that is commonly used in sports drinks among other things.
