Yes, Glenn is good at explaining the details of this. Thanks as always, Glenn.

GBS is typically treated today with IVIG... and is considered an autoimmune type of reaction. In the past before IVIG was available GBS was treated with plasmapharesis ...where the blood is taken out of the body and spun so the antibodies fall out of the serum and then it is put back. People with myasthenia gravis sometimes still have this treatment.

GBS often follows an infectious illness, say food poisoning with Campylobacter bacteria in undercooked chicken or other meat, or a virus. Some modern vaccines have a disclaimer warning on them the GBS may follow injections of these vaccines.

CIDP and GBS are autoimmune illnesses, and treated as such.
All the supplements we discuss that enhance remyelination, may be helpful to healing. But if the autoimmune process is not suppressed, supplements won't be able to keep up with any healing needed.
