Vegetarians are likely to be deficient in which vitamin?

Vegetarians are particularly at risk of deficiency in vitamin B12 because this nutrient is primarily found in animal products such as meat, fish, eggs, and dairy. While certain fortified foods and supplements can provide vitamin B12, individuals who do not consume animal products may struggle to obtain sufficient amounts through diet alone.

Vitamin B12 is essential for various bodily processes, including nerve function, red blood cell formation, and DNA synthesis. A deficiency can lead to serious health issues, such as anemia and neurological problems.

In contrast, vitamins A, K, and E are more readily available in plant foods. For instance, vitamin A can be found in the form of provitamin A carotenoids in colorful fruits and vegetables, vitamin K is abundant in leafy greens, and vitamin E is present in nuts, seeds, and vegetable oils. Thus, while vegetarians may need to be mindful of various nutrients in their diets, the specific concern regarding vitamin B12 stands out due to its exclusive presence in animal-derived foods.
