Vitamin D deficiency in pregnant women will affect fetal bone development, affect the nervous system, and cause congenital rickets.
Vitamin D can promote the absorption of calcium, when the pregnant woman’s body lacks vitamin D, it will cause calcium deficiency in the body, affecting fetal bone development, and also have an impact on the eruption of teeth after birth, such as late eruption of teeth.

Vitamin D deficiency in a pregnant woman’s body during fetal brain development can make brain cells biologically active abnormally, affecting the normal development of the fetal nervous system.
Severe vitamin D deficiency in pregnant women may cause the fetus to develop congenital diseases, such as congenital rickets, which is a systemic chronic nutritional disease characterized by insufficient vitamin D in the body of a child, causing disorders of calcium and phosphorus metabolism, resulting in bone lesions.
