Maternal deficiency in which vitamin contributes to neural-tube defects?

Rationale

Maternal deficiency in folic acid contributes to neural-tube defects.

Folic acid, also known as vitamin B9, plays a critical role in the proper development of the neural tube during early pregnancy. Adequate levels of this vitamin are essential to reduce the risk of neural-tube defects such as spina bifida and anencephaly, making its supplementation vital for pregnant women.

A (Vitamin D) YOUR ANSWER

Vitamin D is important for bone health and immune function, but it is not specifically linked to the prevention of neural-tube defects. While it plays a role in overall health during pregnancy, it does not directly influence the formation of the neural tube.

B (Folic acid) CORRECT

Folic acid is crucial in preventing neural-tube defects, as it aids in DNA synthesis and cell division. Adequate folic acid intake before conception and during early pregnancy is strongly recommended to lower the risk of these defects, making it the key vitamin in this context.

C (Biotin) YOUR ANSWER

Biotin is a B-vitamin that supports metabolism and is necessary for healthy hair, skin, and nails. However, there is no strong evidence linking biotin deficiency to neural-tube defects, so it does not play a direct role in their prevention.

D (Vitamin B1) YOUR ANSWER

Vitamin B1, or thiamine, is involved in energy metabolism and the functioning of the nervous system. While important for overall health, deficiency in B1 has not been associated with neural-tube defects, making it irrelevant to this specific condition.

Conclusion

Folic acid is the vital nutrient needed to prevent neural-tube defects during pregnancy. While other vitamins like D, biotin, and B1 have their own roles in maternal and fetal health, they do not specifically address the prevention of neural-tube defects. Ensuring adequate folic acid intake is essential for expectant mothers to promote healthy neural tube development in the fetus.
