Your brain on -- and off -- caffeine
Date:5/1/2009

physiological effects of caffeine withdrawal.

The researchers also discovered a provocative and somewhat unexpected finding that there were no net benefits associated with chronic caffeine administration.

"In addition to looking at caffeine withdrawal, this rigorous design also permitted comparison of chronic caffeine maintenance with chronic placebo maintenance, which provides unique information about the extent to which there are net beneficial effects of daily caffeine administration," said Stacey Sigmon, Ph.D., research associate professor of psychiatry at the University of Vermont and first author on the study. "In contrast to what most of us coffee lovers would think, our study showed no difference between when the participant was maintained on chronic placebo and when the participant was stabilized on chronic caffeine administration. What this means is that consuming caffeine regularly does not appear to produce any net beneficial effects, based on the measures we examined."
