Which vitamins do vegetarians commonly lack?

Vegetarians may commonly lack certain vitamins and minerals due to dietary restrictions that limit animal-based food sources. The correct choice highlights specific nutrients that can be more challenging to obtain in adequate amounts from a vegetarian diet.

Iron is one of the essential nutrients that vegetarians may fall short of because plant-based iron, known as non-heme iron, is less easily absorbed by the body compared to heme iron found in animal products. Without careful planning, individuals may not meet their iron needs, which can lead to deficiencies.

Calcium is another nutrient that vegetarians might struggle to consume in sufficient quantities, particularly if they do not consume fortified plant-based milk or dairy alternatives. While various green leafy vegetables and legumes provide calcium, it's often not at levels comparable to those found in dairy products.

Vitamin D is crucial for bone health and is primarily obtained through sun exposure and the consumption of fortified foods. Vegetarians, especially those who live in areas with limited sunlight or who do not consume fortified foods, may find it difficult to maintain adequate vitamin D levels.

Vitamin B-12 is another critical nutrient primarily found in animal products. Since vegetarians do not eat meat, they may risk deficiency unless they include fortified foods or take supplements. B-12 is essential for nerve function
