                                While cobalt allergies are relatively uncommon, they pose a significant challenge when addressing vitamin B12 deficiency because all forms of vitamin B12, or cobalamin, contain a cobalt ion. This creates a critical health concern for those who must find safe methods to maintain adequate B12 levels without triggering a hypersensitivity reaction.
