Mrs. D, I am responding here to your stats on B12. Like most people with Polycythemia Vera (my disease #3) I have high B12 readings, usually around 1200. I have a theory that
possibly we don't absorb B12 well, and that's why it's high on blood tests (that is, those with Polycythemia Vera, not MS). I also test high on Omega 3's, although I cannot take
them very well without spastic reaction in the gut. I think I may not absorb them well.
But I am taking small amounts Omega 3 in food, and taking small dose of Alpha Lipoic Acid, which is said to help neuropathy.

My D3 levels went to 85% of normal on just 600 a day. I have increased to 800. As I
explained elsewhere, I don't go above that because D3 is a hormone and might
threaten Porphyria, my Disease #2. I have no proof or stats on that, but I think I went
up pretty well on only 600 D3 a day, and at 800 I am probably normal.
