I can't say which component of my modified oral version of the klenner protocol helped to resolve my sensory ataxia / loss of proprioception BUT it is true that vitamin b1 features prominently in the protocol. if i'd known then what i know now i would have asked for tests of everything and been able to see what happened. but, it still wouldn't tell me which element(s) had the most beneficial effect.
at first I did lean heavily toward crediting the b-complex component of the protocol as the reason for the improvement. in hindsight I would give the vit E megadosing some credit as well. (although I didn't know about E8 complex at the time and was using whatever vit E I could get easily. not the best plan. when working to an old protocol it's always best to merge it with more recent knowledge. eg the klenner protocol has nothing whatsoever about vitamin d3).
i don't have good data on my own vit E levels over time.. i'd be lucky to find one serum value in my files, but prior to dx my dietary vit E intake was certainly marginal. for a very long time. http://neuromuscular.wustl.edu/nother/vitamin.htm#e
