What is Green Tea? Prepared from the dried leaves of the Camellia sinensis plant, green tea is an ancient beverage that has been enjoyed for thousands of years for its simple, soothing taste and its traditional health benefits. Used in China, Japan, India and Thailand, green tea is one of the most popular beverages in the world. Green tea is produced by lightly steaming and then immediately drying the tea leaves. This process prevents oxidation and preserves active constituents in the herb. Green tea is a source of polyphenols, particularly the catechin, epigallocatechin gallate (EGCG), which offer powerful antioxidant protection.* What are the key benefits of Vitacost® Green Tea Complex - Alcohol Free?
