Aus den selben Gründen, aus denen man B12-Mangel entwickelt?

Warum sollte man, wenn man genug nimmt. Vor allem aus einer Quelle, welche nicht an R-Proteine gebunden ist.

Vegans do not need to get their homocysteine or B12 levels checked merely because they are vegan. Rather, being vegan means that you should get a regular, reliable source of vitamin B12 from fortified foods and/or supplements.http://www.veganhealth.org/b12/tested
