The Caffeine-L-Theanine Synergy
Black tea is famous for its caffeine, but it also has L-theanine, an amino acid. Together, they give a balanced energy boost. This is different from caffeine alone, which can make you jittery.
Black tea has about 17.73 mg/g of caffeine and 5.13 mg/g of L-theanine. These two work together to improve focus and calmness. This is not what you get from caffeine by itself.
L-theanine in black tea balances out caffeine’s effects. It prevents the jitters and anxiety that caffeine can cause. This makes for a steady and productive energy level.
“The combination of caffeine and L-theanine in black tea provides a unique synergistic effect, enhancing cognitive performance and concentration without the unwanted side effects.”
Studies show black tea has less L-theanine than green and oolong teas. Green tea has up to 6.56 mg/g and oolong tea has 6.09 mg/g. This makes black tea’s caffeine and L-theanine ratio perfect for focus.
