People all over the world enjoy tea, which is renowned for its calming effects. Its peaceful powers are largely due to the chemical theanine, which occurs naturally in tea leaves.

Benefits of Theanine

Theanine provides flavor, is a relaxant, and is beneficial to the immune system. It produces a calming effect on the tea drinker without inducing drowsiness. It is also an amino acid.

Decaffeinated Tea

Several processes can decaffeinate tea, but none of them affect theanine, which can be found in both caffeinated and decaffeinated tea.

Theanine Vs. Caffeine

Theanine's relaxing, caffeine-fighting abilities are stronger than caffeine's stimulating properties. Therefore, even caffeinated tea drinkers are more likely to feel calm and stress-free than high-strung and jittery.
