Quizplus · Accepted Answer

As we age, our bodies may become less efficient at absorbing and using nutrients, leading to a higher need for some vitamins, including vitamin B12. Additionally, older adults may be more likely to have certain health conditions, such as atrophic gastritis or pernicious anemia, that can impair absorption of vitamin B12. Therefore, a higher RDA is recommended to ensure that older adults are able to maintain the same functional levels of vitamin B12 in their bodies.
