Delayed folic acid supplementation postpartum may pose potential risks, particularly for women who previously had inadequate folic acid intake or those who previously experienced pregnancies with neural tube defects. Folic acid is crucial for DNA synthesis, repair, and methylation, as well as for preventing neural tube defects in developing fetuses [1].

One potential risk of delayed folic acid supplementation postpartum is the increased likelihood of developing megaloblastic anemia. Megaloblastic anemia is a condition characterized by the production of large, structurally abnormal, immature red blood cells (megaloblasts) in the bone marrow [2]. This condition can lead to fatigue, weakness, pale skin, and heart palpitations [3].

Another potential risk of delayed folic acid supplementation postpartum is an increased risk of neural tube defects in subsequent pregnancies. Folic acid supplementation is recommended to begin at least one month before conception and continue through the first trimester to reduce the risk of neural tube defects [4]. Delayed folic acid supplementation postpartum may not provide sufficient time to accumulate adequate folic acid levels in the body before the next pregnancy, thereby increasing the risk of neural tube defects [5].

Moreover, folic acid plays a vital role in mental health. Delayed folic acid supplementation postpartum may increase the risk of developing depression and anxiety, particularly in women with a history of mental health disorders [6]. Folic acid supplementation has been shown to reduce the risk of developing postpartum depression [7].

In summary, delayed folic acid supplementation postpartum may pose potential risks, including megaloblastic anemia, increased risk of neural tube defects in subsequent pregnancies, and an increased risk of developing depression and anxiety. Therefore, it is crucial to continue folic acid supplementation postpartum, especially for women with a history of inadequate folic acid intake or those who have previously experienced pregnancies with neural tube defects [8].
