I have a friend who is a serious bodybuilder and he asked me if wheatgrass juice would be a choice supplement for him to take? Since wheatgrass juice is very nutritious ( wheatgrass juice contains most of the vitamins and minerals needed for human maintenance. It is a whole meal and a complete protein with about 30 enzymes and is approximately 70% crude chlorophyll. Wheatgrass is also an excellent source of calcium, iron, magnesium, phosphorus, potassium, sodium, sulphur, cobalt, and zinc ) I strongly recommended it. Wheatgrass juice is a body builder. It is very high in enzymes and chlorophyll. It contains up to 70% chlorophyll, which is an important body builder. The chlorophyll molecule closely resembles that of the hemin molecule, the pigment that combines with protein to form hemoglobin. The major difference is the chlorophyll molecule contains magnesium as its central atom, and hemin contains iron. The molecular structure of these two substances is almost identical in all other respects. It builds the blood. Wheatgrass juice has been proven to build red blood cells quickly after ingestion. Whew, more science, but I promised to be informative.
