B12 is a vitamin found in a variety of foods, such as fish, meat, eggs, and other dairy products. This vitamin plays an important role within the body’s essential processes, like brain function, energy production, DNA synthesis, and regulation of the nervous system. It is uncommon for most people to be B12 deficient, but the elderly, vegetarians and those infected with HIV are most at risk. The potential of a B12 overdose is not very likely, but it is most certainly possible.
