Impaired kidney function can have an impact on the presence of adequate levels of which vitamin stored in the body?Multiple choice question.DAEK

The presence of impaired kidney function can notably affect the levels of vitamin D in the body, which is stored and metabolized in the kidneys.

Explanation:

1. Vitamin D Metabolism: The kidneys play a crucial role in converting vitamin D into its active form (calcitriol). Impaired kidney function can lead to reduced levels of this active vitamin D, resulting in potential deficiencies.

2. Consequences of Deficiency: A deficiency in vitamin D can impact calcium absorption, leading to bone health issues and other metabolic disturbances.

3. Other Vitamins: While vitamins A, E, and K (the other components of DAEK) are also important, their storage is less significantly impacted by kidney function compared to vitamin D.

Final Answer:

Therefore, the correct vitamin whose levels are most affected in the case of impaired kidney function is Vitamin D.
