It should be noted that caffeine is a very popular and widely studied substance , found in a large number of natural sources, including tea leaves and cocoa beans, plus if we add the synthesized versions to these sources natural, it becomes understandable how many caffeine-rich foods and supplements are available on the market.
But that's not all, as L-theanine is a non-protein amino acid naturally present in green and black tea leaves, which appears to be, in part, responsible for tea's unique effects on the human body .
