Tea polyphenols, caffeine, and theanine are the "characteristic ingredients" of tea, which can be said to be the three treasures of tea.
Tea polyphenols: human body preservatives The tea polyphenol content in tea is as high as 18%-36%, which is the most important ingredient in tea.
It can remove excessive free radicals that are harmful to the human body and help the skin resist the damage of free radicals.
Caffeine: Refreshing and anti-fatigue Although caffeine is called "caffeine", there is more caffeine in tea than in coffee.
After drinking tea, you feel very energetic, which is the effect of caffeine. People in the past drank tea because of its refreshing effect.
Especially some old farmers, if they don't have tea to drink, they have no strength to work.
Theanine: natural sedative There are 26 kinds of amino acids in tea, and theanine is the highest content and the most special amino acid among them, because theanine is almost not found in other plants and is unique to tea.
The effect of caffeine is short-term, while theanine's calming and memory-enhancing effects are only apparent after a long period of accumulation. The two complement each other, making tea refreshing without being overly exciting.
Looking at these ingredients individually, each has its own advantages, and they are all concentrated in a cup of tea and interact with each other to produce greater energy. Tea is undoubtedly the greatest beverage in the world.
