Can we help repair myelin sheath with supplements?

Ive been reading that addinmg Omeg 3's, Vitamin E, Lechitin, and a few other things can help repair the myelin sheath. Does anyone know if this is true?

I am a vegetarian, so I do not get any protein from meat,fish,chicken or eggs.

I use whey protein in shakes,kale,spinach,etc to supplement.

Diagnosed with CIDP last year but Dr did not treat until July of this year when symptoms took a sharp turn for the worse.

Currently having IVIG treatment,just initialdosage. No improvement. Next dose in 3 DAYS!!
