Why are older people at increased risk for vitamin b12 deficiency compared to younger people?

Consequently, why are the elderly at risk for vitamin b12 deficiency?

Vitamin B12 deficiency is common among the elderly. Elderly people are particularly at risk of vitamin B12 deficiency because of the high prevalence of atrophic gastritis-associated food-cobalamin (vitamin B12) malabsorption, and the increasing prevalence of pernicious anaemia with advancing age.

Additionally, who is most at risk for vitamin b12 deficiency? Vegans (people who don't eat any meat, dairy, or eggs) are most at risk for developing a B12 deficiency because, aside from fortified breakfast cereals, the only reliable dietary sources of vitamin B12 are animal-derived products.

Then, which age group is most likely to have a vitamin b12 deficiency?

As a result, vitamin B₁₂ deficiency is relatively common, especially among older people. The National Health and Nutrition Examination Survey estimated that 3.2% of adults over age 50 have a seriously low B₁₂ level, and up to 20% may have a borderline vitamin B₁₂ deficiency.

Why do elderly people need b12?

B12 is important for creating red blood cells and DNA, and for maintaining healthy nerve function. “Getting enough B12 is a challenge for older people because they can't absorb it from food as well as younger people," says Tucker.
