What role does Calcium play for pregnant women?

Calcium plays a crucial role in supporting fetal bone development. During pregnancy, the growing fetus requires a sufficient supply of calcium to develop healthy bones and teeth. The mother’s body also needs calcium to maintain her own bone density, as the demands of the developing fetus can deplete her calcium levels. Adequate calcium intake ensures that both the mother and the fetus remain healthy, preventing complications such as low bone density in the mother and growth issues in the fetus.

Other options, while important in their own right, do not specifically relate to the role of calcium during pregnancy. For instance, enhancing the immune system is primarily due to other vitamins and minerals rather than calcium. Iron absorption is influenced by factors like vitamin C intake, and blood sugar regulation involves hormonal balance and carbohydrate intake rather than calcium. Thus, the emphasis on calcium's role in bone development is critical for understanding the nutritional needs during pregnancy.
