Wheatgrass is a kind of grass. The above-ground parts, roots, and rhizome are used to make medicine. Wheatgrass is often used as a source of nutrients. It contains vitamin A, vitamin C, vitamin E, iron, calcium, magnesium, and amino acids.
Wheatgrass is the freshly sprouted first leaves of the common wheat plant (Triticum aestivum), used as a food, drink, or dietary supplement. Wheatgrass is served freeze dried or fresh, and so it differs from wheat malt, which is convectively dried. Wheatgrass is allowed to grow longer and taller than wheat malt.
Like most plants, wheatgrass contains chlorophyll, amino acids, minerals, vitamins and enzymes. Claims about the health benefits of wheatgrass range from providing supplemental nutrition to having unique curative properties, but these claims have not been scientifically proven.
Wheatgrass juice is often available at juice bars, and some people grow and juice their own in their homes. It is available fresh as produce, in tablets, frozen juice, and powder. Wheatgrass is also sold commercially as a spray, cream, gel, massage lotion, and liquid herbal supplement. Because it is extracted from wheatgrass sprouts (that is, before the wheat seed or “berry” begins to form), wheat grass juice is gluten free, but some dietitians recommend that those with celiac disease avoid it due to the risk of cross-contamination
