What supplement reduces neural-tube-defect risk when started before conception?

Original practice item, not a recalled exam question. Nothing here is recorded.

    Correct: folic acid before conception lowers neural-tube-defect risk.

  • B. Vitamin K

    Vitamin K is used for coagulation-related roles.

  • C. Vitamin C

  • D. Iron only

    Iron treats or prevents anemia but does not replace folate.
