How much green tea should one drink in a day?

Green tea, derived from Camellia sinensis, boasts abundant health benefits. Its key component, epigallocatechin-3-gallate (EGCG), contributes to lowering blood pressure and improving blood sugar control. L-theanine, present in green tea, fosters relaxation and mood enhancement. However, to reap these advantages, you have to aim for around 6 cups a day or consider green tea supplements.
