Improves hematopoiesis

After blood donation, due to the decrease in the number of blood cells, it has a feedback effect on the bone marrow, promotes the release of mature blood cells from the bone marrow reserve, stimulates the bone marrow hematopoietic tissue, promotes blood cell production, and often donates blood according to the prescribed period, so that the bone marrow can maintain vigorous vitality.

Reduces blood lipids

It can reduce a part of the thick blood in the body, so that the blood is naturally diluted and the blood fat is reduced.
