Years ago, wheatgrass has been given to patients with iron deficiencies and proved to be effective in restoring the blood to normal.
Chlorophyll in wheatgrass rebuilds the bloodstream. More recent research indicates that some porphyrins (ringed structures in chlorophyll) stimulate the formation of the protein portion of the hemoglobin molecule. This explains the effect of chlorophyll in blood production.
Other than chlorophyll, iron, niacin (B3), cyanocobalamin (B12), folic acid, copper, potassium and protein in wheatgrass, are all involved in healthy red blood cell production, making wheatgrass an excellent remedy for anemia and other blood disorders.
