I've explored, but am unaware of any nutrition or supplements that truly accelerate recovery from GBS. There may be a benefit from taking Omega 3 fatty acids & certain B-vitamins (B6 & B12, I think), though I don't know that the efficacy of those supplements has been proven. My answer may be outdated by new research, breakthroughs may reveal new diet strategies to improved GBS recovery or symptom management. Internet research is your friend.
