I currently take the following prescribed medications for depression and adult ADHD (diagnosed in Feb. 2013): Brintellix (20 mg.), Concerta (36 mg.) and Strattera (80 mg) in the morning, and Concerta (18 mg.) at noon. I also typed in that I take Vitamin B-12 oral (sublingual) and a Vitamin B-complex supplement, Vitiamin C, and Fish Oil supplements (Costco). I received a message online just now, warning me about
the latter. Why might this be a problem?
