Mental Focus and Thinking Fast!
In a study comparing habitual and non-habitual coffee drinkers, they found that the best results for visual attention were achieved with 200mg of caffeine, a dose not available in your available cup of coffee. In comparison, a normal cup of coffee contains 75mg of caffeine while Busy Bee's The Sting High Caffeine Blend contains around 225mg of caffeine per 8 oz. serving.
In heavy coffee drinkers however, visual attention improved with a high dose of around 400mg of caffeine due to the build up in tolerance.
Caffeine and reaction time
The European Food Safety Authority has also studied and concluded that caffeine can increase not only alertness but also reaction time. They also found that the caffeine improved participants' accuracy on a test called the "Stroop test," which measures skills such as planning and focusing.
With the Philippines having a heavy coffee drinking community, your normal cup of coffee may not be enough to give you that energy boost and focus you need. Try out Busy Bee's The Sting and feel the difference.
