In Mediterranean countries people live to a ripe old age. The olive is a key constituent of their diet... the most nutritious part of the olive tree is the leaves. From the leaves we get Olive Leaf Complex - a highly nutritious food and powerful antioxidant. Antioxidants help reduce free radical damage and may contribute to heart and cardiovascular health and assist in the maintenance of general well being. Olive Leaf Complex has 400% more antioxidant capacity than vitamin C... probably the most commonly used antioxidant. Comvita Olive Leaf Complex is made solely from fresh, alive, olive leaves picked each day before sunrise when they are at their most potent.
