My 18 year old daughter is at college and wants to find a supplement that enhances concentration and memory, because she can t recall everything she reads in the textbooks. She takes Fluoxetine 20 MG for her OCD. She asked me about taking one of these supplements: Noopept, Limidax & Pramiracetam, but I don t know anything about them, or if they are safe or effective. Can you recommend a supplement to help my daughter study, and that is safe to take with Fluoxetine? Thank you.
