Has anyone's dysautonomia actually been caused by vitamin deficiencies?

I am deficient in several and don't know where to start with getting my levels up with so many to consider. Started to get symptoms of dysautonimia a few months after having my second child which was made ten times worse after having covid and then the vaccine.

Has anyone's dysautonomia actually been caused by vitamin deficiencies? I don't actually know the cause of mine but wondered if it could be this. Had an iron infusion 2 weeks ago but feel no different!
