Folic acid supplementation

A 26-year-old woman is taking valproic acid for her stable Juvenile Myoclonic Epilepsy. There has been no other seizure medication which controlled her convulsive seizures except for valproic acid. She is taking prenatal vitamins since she is sexually active. Would you recommend higher dose of folic acid to her? How would you counsel her regarding the evidence for the dose you are recommending? Would it change your management if she was taking lamotrigine, topiramate, or levetiracetam?
