Yerba Mate is packed full of difficult to find, important nutrients: Vitamins B-1, B-2, A, riboflavin, carotene, colin, pantothenic acid, inositol and 15 types of amino acids (F. Alikaridis 1987). It also contains significant quantities of the all important iron, potassium, and magnesium minerals, something Green Tea lacks. As noted by The Pasteur Institute and the Paris Scientific Society, "It is difficult to find a plant in any area of the world equal to Mate in nutritional value."
