As a vegan, Ada was careful to take vitamin B12 supplements but didn't take folic acid supplements until well after she realized she was pregnant (7 weeks gestation). Which of the following is true with respect to the risk of neural tube defects in her baby? Because Ada doesn't eat dairy, her diet is low in folate and she is at high risk for neural tube defects. Because she took vitamin B12 supplements, this will prevent neural tube defects regardless of her folate status. Because Ada is vegan, she was likely consuming enough folate in her regular diet so she is at low risk. Because she was taking vitamin B12 supplements, this would mask the effects of folate deficiency so she is at high risk. Because she took folic acid supplements at 7 weeks, this was early enough to allow the neural tube to close properly.
