Explanation:

The most well-known is caffeine, a potent stimulant that you can also get from coffee and soft drinks. Tea also contains two substances related to caffeine: theobromine and theophylline. Finally, it provides a rather unique amino acid called L-theanine, which has some very interesting effects on the brain.
