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.
