Vitamin B12

[ASLAN]

Hi,
for an herniated disc in L4, now my foot is paralysed.
At the moment, following the prescription of my neurologist 
I take 2000 mcg of cyanocobalamine (in tablets)every day.
I don't know the neurotrofic properties of cyanocobalamine, but I
would like to know if there is anything better than vitamin B12 as
neurotrofic factor.
Thank you in advance
