Been taking Adderall since October. Just had a blood test and had a Folic Acid deficiency. Is this a side effect of Adderall. Couldn't find any thing about it. Has anyone else had this problem?

I'm not a medical doctor, however, I've never (personally or professionally) heard of that as being an artifact of either one.

That certainly doesn't mean it couldn't happen. I've just never read or heard about it.
