Letter to the Editor

Sir: We appreciate Dr. Frankenburg’s thoughtful letter outlining her reservations about the proposed use of folate supplementation in the psychiatric field. Dr. Frankenburg points out a number of concerns regarding potentially harmful effects of folate. We have considered these issues and conducted some additional literature review to address her questions.
