Below is an extract from it;
"Vitamin B12 has no established toxic threshold. There is no evidence that there even is one. I'd also suspect that the "normal" values might better be expressed as "typical", which may or may not be "optimal". Extra B12 in the blood serves as an especially efficient scavenger for the potent oxidant peroxynitrite, so I'd say this B12 level is a positive finding, not an adverse one. The ferritin level is worth efforts to increase, though."

There are many vegan foods fortified with B12. They include non-dairy milks, meat substitutes, breakfast cereals, and a type of yeast.
