Hello Liza,
Welcome to the NeuroTalk Support Groups.
I'm sorry to read about your injury. You've posted on the PTSD Forum so I'll post the link to the TBI/PCS Forum below...
Traumatic Brain Injury & Post Concussion Syndrome Forum
At the top of that forum there are 'Sticky' threads. They include information, useful websites and other resources.
One of those threads is the
Vitamin & Supplements Regimen Thread
There is also the main vitamin forum
Vitamins, Nutrients, Herbs & Supplements Forum
