What is the role of Vitamin D supplements during pregnancy?

Vitamin D plays a crucial role during pregnancy primarily in supporting fetal bone health and development. Adequate levels of Vitamin D are essential for the proper metabolism of calcium and phosphorus, which are vital minerals for the formation of a healthy skeletal system in the developing fetus. Insufficient Vitamin D can lead to complications such as low bone density and increased risk of skeletal deformities in the newborn.

Additionally, Vitamin D contributes to the immune system functioning and may influence fetal growth and development positively. While it is important for overall health, especially in the context of pregnancy, its direct impact on fetal bone health is recognized as one of its most significant roles during this time. Other options related to increasing energy levels or enhancing digestive health are not directly linked to Vitamin D's primary functions, and morning sickness is typically influenced by hormonal changes rather than vitamin supplementation.
