Vitamins C contained inside Japanese green tea do not break up easily.

Japanese tea contains a variety of ingredients such as catechins, caffeine, and vitamins.

Usually, Vitamins C are known to weaken under heat. But Japanese tea, even when plunged into hot or warm water, is a food which does not lose its Vitamin C easily. The Vitamins C are protected by the catechin contained inside Japanese green tea. Green tea is a rare food that can fully provide the benefits of Vitamins C.
