Frequently Asked Questions
What is Yerba Mate?
Yerba Mate (Ilex paraguariensis) is a tree native to South America whose leaves are brewed into a traditional energizing tea. It contains caffeine, theobromine, polyphenols, and saponins, making it one of the most nutrient-dense functional beverages in the world. It has been consumed for centuries in Argentina, Paraguay, Uruguay, and Brazil.
How much Yerba Mate is safe to drink daily?
Most research supports 1-3 cups of brewed yerba mate per day as safe and beneficial for most adults. This provides approximately 65-130mg of caffeine. Pregnant women should limit intake to 1 cup daily. Allow the beverage to cool below 65°C before drinking, as very hot beverages are associated with increased esophageal cancer risk.
How does Yerba Mate compare to coffee and green tea?
Yerba Mate contains less caffeine than coffee but more than green tea, and uniquely combines caffeine with theobromine for a smoother, more sustained energy boost. It has a higher antioxidant capacity than green tea in several comparative studies, and its saponins provide additional anti-inflammatory and immune-modulating benefits not found in coffee or tea.
