Your claim

Vitamin B12 is found mainly in foods that come from animals.

What we found

Vitamin B12 is found naturally in foods like meat, fish, eggs and milk products. People who eat few or no animal foods may not get enough and can ask a doctor about it.

Why we gave this result

NIH says only animal foods naturally have vitamin B12. The NHS lists meat, fish, milk, cheese and eggs and says it is not found naturally in fruit, vegetables or grains.
