Which vitamins are classified as fat-soluble?

Fat-soluble vitamins are classified based on their ability to dissolve in fats and oils, as opposed to water-soluble vitamins, which dissolve in water. The vitamins that fall into the fat-soluble category include vitamins A, D, E, and K. These vitamins can be stored in the body's fatty tissue and liver, which allows for a reserve that the body can draw upon when needed.

Vitamin A is crucial for vision, immune function, and skin health. Vitamin D plays an essential role in calcium absorption and bone health. Vitamin E is an antioxidant that helps protect cells from damage, while vitamin K is vital for blood clotting and bone health. The correct identification of these vitamins as fat-soluble highlights their unique absorption, storage, and functionality compared to the water-soluble vitamins, which need to be replenished more regularly through diet as they are not stored in the body to the same extent.
