High B6 and B12
my B12 level always runs high and was over 2000 one year. The surgeon just shrugged and said I could probably cut back on it a little, since it was clear I was absorbing it well and my body didn't need as much as I was taking. It runs around 1000-1200 now.
a lot of people on here like theirs at 1000 or more since they feel better when it's at that level.
at any rate, I don't think a high B12 level is problematic.
