I got in touch with a neurosurgeon who is primarily using omega 3 fatty acids as a way to help rebuild neural connections in patients with TBI. He said that every patient is different. It did recommend a brand 'nordic naturals' which by chance I have been taking due to then not having a fishy aftertaste!
His website is
http://www.brainhealtheducation.org/omega-3-protocol/
And he recommended to me the Omega 3 protocol. Check it out!
Lots of great info on there as well.
He also recommended a broad B complex alongside the Omega 3's.
Hope that helps!
Cheers!
