Wheat grass is the young plant grown from wheat berries. It contains high levels of many nutrients, including iron, magnesium, manganese, and zinc. One of the most often cited benefits of wheat grass is that it is about 70% chlorophyll, the green pigment that plants use to convert sunlight into energy. Chlorophyll has a similar chemical structure to hemoglobin, and wheat grass juice is being researched for its potential to support healthy hemoglobin levels and reduce the need for blood transfusions in individuals with thalessemia and anemia-related disorders.
