It is also suitable for a wide range of people, including elderly people with iron deficiency anemia, children with iron deficiency anemia, pregnant women and lactating women with iron deficiency anemia. Iron polysaccharide complexes provide iron to increase the formation of hemoglobin and raise the concentration of hemoglobin for the purpose of treating anemia.

In order to reduce the digestive side effects, it can be taken during or immediately after meals, which can effectively reduce the digestive side effects of iron polysaccharide complex, and do not drink tea when applying iron polysaccharide complex, so as not to affect the absorption of iron.
