Yerba Mate tea is a high-antioxidant leaf with high amounts of minerals and vitamins (potassium, manganese, phosphorus, sodium, nitrogen, etc. and vitamins A, C, E, etc.) that can help promote healthy gastrointestinal tract. Yerba Mate naturally contains caffeine. No additional caffeine has been added.
P.S. Make sure to add a tea infuserto your cart -- they're kind of important, lol.
