Which statement about fat-soluble vitamins is true?

• A. They are stored in fat tissue
• B. They must be consumed daily
• C. They are excreted in urine quickly
• D. They cannot be stored.

Answer: (A)

Fat-soluble vitamins are stored in the body, primarily in fat tissue and the liver, so daily intake isn’t required because the body can draw on those reserves. They are absorbed with dietary fats and can accumulate if consumed in excess, which is why high intake—especially from supplements—can lead to toxicity. This storage also means they aren’t excreted quickly in urine, unlike many water-soluble vitamins that are lost more readily and need more regular replenishment. The statements that they must be consumed daily, that they are excreted quickly in urine, or that they cannot be stored don’t fit this pattern.
