Benefits of zinc supplementation for infants and children.
Improves digestive function: The metabolism of fats, proteins and carbohydrates in the human body cannot be achieved without the participation of enzymes, of which there are many, and many of which cannot be achieved without zinc. As far as we know, zinc is related to the activity of nearly 300 enzymes in the body, and zinc can promote the activity of many enzymes in the body and improve the digestive function of babies.
Promote growth and development: Zinc is very important for infants and children in the growth and development period. Zinc is widely involved in the metabolism of nucleic acids and proteins, speeding up cell division and keeping cell metabolism at a high level, thus promoting the growth and development of babies.
Enhances immune function: Zinc improves the immune function of cells and enhances the phagocytic ability of macrophages, thus playing a bactericidal role and increasing resistance.
Promote intellectual development: Zinc can promote brain cell development and division, thus laying a solid material foundation for children’s intellectual development. Proper supplementation of zinc can strengthen memory function and reaction ability.
