I can't guarantee that Omega 3 will help with her brain injury, but it is very good for the brain. You will definitely want her to take Lecithin. Lecithin is a basic building block for the brain. I also take a memory improving supplement called Piracetam. When you take Piracetam with Lecithin it increases the effectiveness. You also my want to read up on Lithium Oronate. Lithium Oronate is a mineral supplement, only a tiny fraction of the strength of the drug Lithium. Lithium Oronate is supposed to be a brain chelator, so if you are concerned about Alzheimers you will want to make this part of your arsenal.
