Which of the following vitamins can be stored in the liver?

  • (A) Vitamin A
  • (B) Vitamin C
  • (C) Vitamin D
  • (D) Vitamin K
  • Vitamin A is a fat-soluble vitamin that is stored in the liver in the form of retinyl esters. In the liver, it tends to accumulate in the space of Disse in stellate cells. If the body needs to utilize some of its stored vitamin A for purposes like seeing or fighting infections, the liver draws upon its reserves of the vitamin.
  • Vitamin C: This is a water-soluble vitamin. The body does not store it in significant amounts; any excess is excreted through urine, meaning it must be consumed daily.
  • Vitamin D: While Vitamin D is fat-soluble and is stored in the liver and fatty tissues, it is not considered the "primary" vitamin stored there in the same massive concentrations as Vitamin A. Much of it also undergoes chemical conversion in the liver rather than just storage.
  • Vitamin K: Vitamin K is also stored in the liver, but only in very small amounts that are depleted rapidly. Because of its high turnover rate, the body requires a more frequent supply compared to Vitamin A.
