Which statement best describes fat-soluble vitamins?

• A. All vitamins are water-soluble.
• B. Water-soluble vitamins are stored in fat.
• C. Fat-soluble vitamins require water for absorption.
• D. Fat-soluble vitamins dissolve in fat and are stored in tissues, with potential to accumulate.

Answer: (D)

Fat-soluble vitamins are the ones that dissolve in fat and can be stored in body tissues, especially the liver and adipose tissue. Because they’re stored, they can build up if you take them in excess, leading to potential toxicity. They also require dietary fat for absorption in the gut and are transported in the bloodstream with lipids. This is different from water-soluble vitamins, which aren’t stored in large amounts and are usually excreted in urine, necessitating more regular intake. So, describing fat-soluble vitamins as dissolving in fat, being stored in tissues, and having the potential to accumulate is the accurate picture.
