Best treatment for neural regeneration/pancreatic nerve?

Since type 1 diabetics form damage on the pancreatic nerve, I want to know what supplements and foods (at what dosage) I need to start on to give my body a boost on removing scar tissue and growing new nerves. I have read that raw egg yolk is the best source for B-vitamin complexes. Lion's mane extract/Hericium Erinaceus is also something I'll look for.

starting on vitamin D3 10,000iu / 250mcg tommorrow.
