Which vitamins are fat-soluble?

• A. A, D, E, & K
• B. B & C
• C. A & C
• D. D & K

Answer: (A)

Fat-soluble vitamins dissolve in fat and are stored in the body's tissues, especially the liver and adipose tissue. They require dietary fat for proper absorption and can accumulate if taken in excess, so they’re not needed every day in the same way as water-soluble vitamins.

The vitamins that fit this group are A, D, E, and K. In contrast, B-complex vitamins and vitamin C are water-soluble, meaning they dissolve in water, aren’t stored in large amounts, are excreted in urine, and typically need more regular intake.
