The invention discloses a polypeptide composition for improving anemia symptoms and a preparation method thereof, belonging to the technical field of polypeptides, wherein the polypeptide composition comprises the following components in percentage by weight: 10-49% of a filling agent, 0.1-5% of a lubricating agent and the balance of a blood protein polypeptide A or a blood protein polypeptide composition preparation B; the hemoglobin polypeptide A comprises heme iron, and is obtained by adding an anticoagulant into fresh animal blood, then performing centrifugal wall breaking and heating, enzymolysis, ultrafiltration, concentration and drying; the blood protein polypeptide composition preparation B is prepared by adding water with the weight 3-6 times of the blood weight into fresh animal blood, then adding 0.4% -0.9% of animal protein hydrolysis complex enzyme for enzymolysis and stirring, then adding a medicinal and edible extract D, heating and centrifuging, ultrafiltering, concentrating and sterilizing. Compared with the traditional iron supplement, the polypeptide composition can be directly absorbed by intestinal mucosa cells, and is not easy to generate any digestive tract stimulation symptom. |
