Wheatgrass is the young, leafy growth of Wheat. Since the early Twentieth century it has been used as a high-nutrition food thanks to the very broad range of vitamins and minerals it provides. Wheatgrass is produced with minimal processing. Wheat is grown until the young leaves of the plant are in their most nutritionally rich and fertile phase, before the ear - or seed head - develops. It is then harvested, cleaned, dried and milled into a fine powder. Wheatgrass is high in Vitamin A and C, which help maintain healthy vision and contribute to normal brain function.
