Which vitamins are classified as fat-soluble?

Vitamins classified as fat-soluble are those that can be stored in the body's fatty tissue and liver. This classification includes vitamins A, D, E, and K. These vitamins have significant roles in the body, such as supporting vision, promoting calcium absorption, acting as antioxidants, and playing crucial roles in blood clotting, among others. Because they are stored in fat, fat-soluble vitamins can be accessed when the body needs them, but they also require dietary fats for proper absorption during digestion.

In contrast, the other options include water-soluble vitamins, which must be consumed regularly since they are not stored in the body and are excreted more readily. For instance, Vitamin C and the B vitamins like B1, B2, and B3, as well as B6, are all part of the water-soluble group. These vitamins have different functions and absorption requirements, and they do not provide the same long-term reserves that fat-soluble vitamins do.
