[#974] Which of the following vitamins is generally excreted by human in urine?
Correct Answer
(C) Vitamin D
Explanation
Solution: Question: Which vitamin does our body usually get rid of through pee? Explanation: Vitamins are essential nutrients. Our bodies need them to work properly. But not all vitamins are stored the same way. Some vitamins, like vitamins A, D, E, and K, are fat-soluble . This means they dissolve in fat and are stored in our body's fatty tissues and liver. Our bodies don't easily get rid of them. Other vitamins are water-soluble , meaning they dissolve in water. These are vitamins B and C. Our bodies don't store them as much. Any excess that we don't use is usually passed out in our urine. Therefore, Vitamin C (a water-soluble vitamin) is the one generally excreted (removed) from the body in urine. So the correct answer is B: Vitamin C
