Which Perks Your Brain Up Better? Green Tea or Coffee
Green tea has a substance called l-theanine that coffee lacks and it’s this component that can have cognitive benefits over coffee.
Caffeine in your green tea (as opposed to tea that is specifically decaffeinated) can contribute to increased mental sharpness, and brewing a bit longer can increase the caffeine in the component you consume.
Mental sharpness after caffeine is most potent in the first hour after you consume it.
Teas mostly aid hydration, coffee can be dehydrating.
So, tea wins for a better brain pick up.
