Özet: 

Gebelikte folat eksikliği ile nöral tüp defektleri (NTD) ve bazı konjenital anomaliler arasında ilişki kuran birçok çalışma mevcuttur. Nöral tüp defektlerinin önlenmesinde folik asit proflaksisin ne şekilde yapılacağı literatürde yaygın tartışmalara konu olmuştur. Bu derlememizde, gebelikte folik asit kullanımını güncel literatürler ışığında irdelemeyi amaçladık.

Many studies relate folate deficiency during pregnancy
with neural tube defects and congenital disorders. How folic acid prophylaxis should be carried out has been a contentious topic in the literature. In this review, we aimed to
examine folic acid use according to current literature.
