Lemon actually prevents the oxidation of the tea Catechins, you can also use ascorbic acid or VitC tablets just break a 500 mg tablet in 4 parts and swallow one of the pieces with the tea, store the rest in an air tight container and use within 24 hrs ...about 10ml of fresh lemon juice is enough.add the juice to a cup filled with tea just before you drink it.

How does lemon raise antioxidents? How much lemon should be used per serving? Should lemon be added to water before or after steeping?

In another video you say that tea from japan is better than tea from china because of the lead. But I don‘t find white tea from japan. So whitch is better: Green tea from japan or white tea from china?
I would be very thankful for help in this question.
