What characteristic is true for fat-soluble vitamins?

Fat-soluble vitamins, which include vitamins A, D, E, and K, are characterized by their ability to dissolve in fats and oils. This characteristic allows them to be stored in the body's fatty tissues and liver, leading to the potential for accumulation. Because they are not readily excreted in urine like water-soluble vitamins, which dissolve in water and get excreted more easily, excess consumption over time can result in toxic levels in the body.

The risk of toxicity is particularly notable with vitamins A and D, as they can lead to serious health issues when consumed in excessive amounts. Understanding this characteristic is important for both dietary planning and monitoring vitamin intake, especially in individuals who take supplements or have dietary preferences that may lead to high levels of these vitamins.

Other answer choices highlight aspects that do not align with the properties of fat-soluble vitamins, reinforcing the understanding of their unique characteristics.
