Which nutrient is most important to ensure before conception and during early pregnancy?

Folic acid is the most important nutrient to ensure before conception and during early pregnancy due to its critical role in fetal development. It is essential for the proper formation of the neural tube, which eventually develops into the baby's brain and spinal cord. Adequate intake of folic acid before conception and during the first trimester significantly reduces the risk of neural tube defects and other congenital abnormalities.

Health organizations commonly recommend women of childbearing age consume a daily supplement of folic acid, along with its presence in a balanced diet rich in fruits, vegetables, and whole grains. This preventive measure is particularly crucial as neural tube formation occurs very early in pregnancy, often before many women realize they are pregnant. Therefore, ensuring sufficient folic acid before conception is vital in establishing a healthy foundation for pregnancy.
