It may seem strange, but tea leaves contain more caffeine than coffee beans. However, when brewed, the caffeine in the tea combines with tannins (tannins) to form caffeine tannate. It does not have such a pronounced tonic effect.

“Caffeine tannate, also called theine, has a milder effect (mainly on the heart). It is excreted from the body faster, which prevents its accumulation. And, unlike pure caffeine, it does not have such a bitter taste,” said expert and Doctor of Biological Sciences Mikhail Goncharov.

In addition to caffeine, this drink contains many polyphenols, which are antioxidants. They help neutralize free radicals (reactive oxygen species) that trigger the oxidation process.

Oxidative stress is believed to be linked to the development of cardiovascular disease, cancer, and Alzheimer’s disease. Therefore, drinking antioxidant-rich tea can be considered a preventive measure against cancer and dementia.
