NO CAFFEINE, AN ALTERNATIVE TO COFFEE
Some consumers consciously reduce the amount of caffeine they consume
Scientific research indicates that caffeine improves basic cognitive functions such as attention, vigilance, and response time. At the same time, however, in addition to its benefits, caffeine can cause a number of problems, particularly among those who feel tired or weak. Too much caffeine leads to perceived anxiety and sleep problems, which are factors limiting brain work. Caffeine has not been proven to support key brain functions beyond focus or creativity. Some studies suggest that caffeine intake may inhibit the absorption of vitamins.
