Is a natural food supplement that is made from the cereal grass juice, such as immature grasses of wheat, barley and oats. This product contains every nutrient necessary to sustain life. The vitamins, minerals and enzymes in GreenLife are alive, active and balanced by Nature. It is Nature's answer to a multi-vitamin and multi mineral supplement. It is harvested at 21 days and cut before the culm stage so there is NO GLUTEN in it. It also has vitamin c in it. Ascorbic acid is to prevent the oxidation of those more elusive enzymes and vitamins.
