###Human: Can taking less Folic acid during pregnancy by Crohn's patient affect baby? ###Assistant: Hi. I have read your concern. You need not worry or be anxious about it. Although absorption of Folate may be disturbed because of your Crohns, taking 400 mcg for four months will be good enough. Meaning, you are not deficient from it from the very start but since you are now pregnant, additional Folic acid is needed to be used by the baby. I suggest you have your serum Folic acid test done so as to make sure that everything is not below normal. Because Chrons as you already may know effects the absorption of folic acid.
