Wheatgrass is sprouted from the seed, technically called cotyledon, of the common wheat field plant but lacks gluten protein.
Wheatgrass is consumed as a dietary supplement because it is highly nutritious.
Compared to other greens, wheatgrass contains more protein, vitamin E and phosphorus that either broccoli or spinach.
The powdered herb is often encapsulated, or added in small amounts to smoothies, soups and other foods.
