What is the characteristic of fat-soluble vitamins?

Fat-soluble vitamins are characterized by their ability to dissolve in fats and oils. This property allows these vitamins—such as vitamins A, D, E, and K—to be absorbed along with dietary fats through the intestinal tract. Once absorbed, they can be stored in the body's fatty tissues and liver, which is a significant distinction from water-soluble vitamins that require regular intake because they are not stored and are excreted easily through urine.

Understanding this aspect of fat-soluble vitamins is crucial for nutrition, as it affects how they should be consumed and incorporated into diets. The ability to be stored means that while these vitamins play essential roles in various bodily functions, there is also a potential risk of toxicity if consumed in excessive amounts over time. This characteristic highlights the need for a balanced intake rather than a focus on high doses, which can lead to health complications.
