Product Benefits

Two additional active ingredients (besides the iron bisglycinate) are phycocyanin and Angelica sinensis. Phycocyanin is a blue pigment which helps stimulate erythropoiesis (the production of red blood cells) and oxygen transport. Angelica sinensis improves hematopoiesis and thrombopoiesis (the prodution of blood cells and platelets in the bone marrow) and contains polysaccharides which suppress the expression of hepcidin, a peptide hormone secreted by the liver which regulates iron metabolism in the body (excess hepcidin implies a decrease in circulating iron).
