Vitamin B12 Foods vs Supplements
Can people get enough vitamin B12 from food? The answer is yes for many. If they consume foods that are rich in vitamin B12 regularly, they can get all of the B12 that they need.
However, supplements may help people who need more vitamin B12 than their diet provides or who have problems with absorption. Supplements should be used as needed instead of replacing a healthy diet.

Vitamin B12 is not known to be toxic because it is water soluble and excess amounts are usually excreted by the body. No upper limit for intake has been set for vitamin B12.
Nevertheless, taking large doses of vitamin B12 supplements unnecessarily is not helpful. If you think that you need more vitamin B12, discuss testing and treatment with a healthcare provider.
