I am doing a bit of research for my local support group and thought this might be a bit easier than trying to narrow down on the Web. All I can tell you is that when Ted left an HMO to private neurologist, he asked about B-12. Seems they had tested him for it and it showed very low, but due to changes in doctors, it had slipped through the cracks. Neurologist explained that B-12 has special meaning for a neurologist. He said that Ted needed shots since in Scandanavian males, often the stomach would not absorb it. He started him on shots and it made a tremendous difference for him ... and also for his not being so tired all the time. He gives himself the shots now every other week.
