Vegetarians often find themselves at risk for vitamin B12 deficiency because this essential vitamin is primarily found in animal-based foods such as meat, fish, dairy, and eggs. Since vegetarians avoid these foods, they may not consume adequate amounts of vitamin B12, which is crucial for red blood cell formation, neurological function, and DNA synthesis.

Without sufficient intake of vitamin B12, vegetarians may experience symptoms such as fatigue, weakness, constipation, loss of appetite, and neurological issues. It is important for vegetarians to seek out fortified foods, such as certain plant-based milk or breakfast cereals, or consider supplementation to meet their vitamin B12 needs and maintain overall health.
