I was wondering about repairing nerve damage. I read that it is damage to the myelin sheath that causes the symptoms, and that b12 can repair it. I also recently read that it is the methyl type of b12 that will do this and not the other forms. Is this correct? I ask because going into self injecting for my daughter, and wanting to get high levels into her to help this, I was thinking that buying the methyl form in a spray to take daily would help with this. Would it? Or is it only by injecting it that the amount would be enough to repair? Also I wasn't going to do this whilst the jabs were three times a week, only when we cut them back to wherever the level is right for her, because it seems a bit pointless if having injections close together. Any thoughts? I don't want to go down the road of injecting the methyl form, not without monitoring by the doctor etc. We use Hydroxo.
