Which vitamins are fat-soluble?

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

Answer: (D)

Fat-soluble vitamins dissolve in fats and are absorbed along with dietary lipids, requiring bile for emulsification and pancreatic enzymes for digestion. They’re packaged into chylomicrons and travel through the lymphatic system, and they can be stored in the liver and adipose tissue for longer periods. This storage means they don’t need to be consumed every day, but it also means they can accumulate if taken in excess. The vitamins that belong to this fat-soluble group are A, D, E, and K. The other vitamins, B and C, are water-soluble: they’re not stored extensively and are more readily excreted by the kidneys, so they typically need more regular intake.
