Vitamin B12 is primarily obtained from which type of sources?

Vitamin B12 is primarily found in animal products, making this the correct answer. This vitamin plays a crucial role in various bodily functions, including the production of red blood cells, DNA synthesis, and the proper functioning of the nervous system. The primary sources of B12 include meat, fish, dairy products, and eggs.

Vegetable sources are not reliable for providing adequate B12, as this vitamin is not naturally found in plant-based foods. While some fortified foods, such as certain plant-based milk alternatives and breakfast cereals, can contain added B12, these are not natural sources of the vitamin. Nuts and legumes, while healthy snacks and sources of other nutrients, do not contain B12. Grains and cereals also typically do not provide this vitamin unless they are fortified. Thus, animal products are the best and most direct source of Vitamin B12 for individuals, underscoring the importance of these foods in diets that are not supplemented with fortified options.
