Compound Zinc, Iron and Calcium Oral Solution has the function of zinc, iron and calcium supplementation. When zinc is deficient, it will affect the renewal of taste buds, leading to loss of appetite, anorexia, abnormal development of the nervous system, decreased immune function or insufficient protein synthesis in retinal cells, resulting in night blindness. In addition, iron deficiency will lead to iron deficiency anemia, which will result in pallor, fatigue and weakness. Iron supplementation can strongly promote the synthesis of hemoglobin and improve the symptoms of iron deficiency anemia. Calcium in daily life is mainly derived from food, such as milk and shrimp skin. Through sunlight exposure, vitamin D in the skin can be turned into active vitamin D, which can promote the absorption of calcium. Compound zinc, iron and calcium solution can not only supplement zinc, but also iron and calcium, all in one go.
