Barley grass
Barley grass refers to the young, green barley plant, which produces grain in its later stage of growth. In human nutrition, barley grass is a popular dietary supplement, as it is particularly rich in vitamins, minerals, trace elements, enzymes, antioxidants and secondary plant compounds. Its nutrient density is higher than that of other green plants.
For example, barley grass is rich in vitamin C, vitamin E, B vitamins, calcium, phosphorous, magnesium, copper, zinc, essential amino acids and chlorophyll.
