What is the primary source of vitamin B12?

• A. Vegetables and fruits
• B. Animal products such as meat and dairy
• C. Grains and legumes
• D. Fish and seafood

Answer: (B)

Vitamin B12, also known as cobalamin, is primarily found in animal products. Foods such as meat, fish, poultry, eggs, and dairy products are rich sources of this essential vitamin. The body cannot synthesize vitamin B12, so it is crucial to obtain it from dietary sources. This vitamin plays a significant role in the formation of red blood cells, neurological function, and DNA synthesis. While fish and seafood are excellent sources of B12, they are considered part of the broader category of animal products. Therefore, although seafood contributes to the intake of B12, the classification of animal products encompasses a wider array of foods that provide this vitamin. Other choices like vegetables and fruits, as well as grains and legumes, do not contain significant amounts of vitamin B12, making them inadequate sources for those who consume a plant-based diet unless fortified versions are chosen.
