Frequently Asked Questions
What is South Korean green tea?
South Korean green tea is made from Camellia sinensis leaves cultivated in Korea's mountainous regions. It is rich in catechins (especially EGCG), L-theanine, and caffeine, and has been extensively studied for cardiovascular, cognitive, and antioxidant benefits.
How much green tea should I drink daily and is it safe?
Two to three cups daily is generally recommended for health benefits. Green tea is safe for most adults, but high-dose extracts exceeding 800mg EGCG per day have been linked to rare liver toxicity. Caffeine-sensitive individuals should moderate intake.
How does Korean green tea compare to Japanese or Chinese green tea?
Korean green tea is processed similarly to other green teas but is often pan-fired rather than steamed, yielding a slightly nuttier, less astringent flavor. The catechin and L-theanine content is comparable, with variations depending on cultivar, altitude, and processing. All high-quality green teas offer similar evidence-backed health benefits.
