Your 2000 B12 result (on just a B complex) shows that you do not malabsorb severely. You may or may not be headed in that direction.

I would take a reasonable B complex, at least 1000 mcg methylcobalamin B12 at a different time, and you can find an excellent thread about magnesium by mrsd. I believe it is at the vitamin forum.

I wish I had known to take methylcobalamin right away. If I had begun taking 5000 mcg methylcobalamin right away, instead of getting merely adequate treatment after eventually being diagnosed, I would be a lot better off.
