Which vitamins are classified as fat-soluble?

The classification of vitamins into fat-soluble and water-soluble categories is based on their solubility in fat or water, which influences their absorption and storage in the body. Fat-soluble vitamins are those that dissolve in fats and are typically stored in the liver and fatty tissues.

Vitamins A, D, E, and K are identified as fat-soluble because they share the characteristic of dissolving in lipids. This allows them to be absorbed along with dietary fats in the intestines and stored in the body's adipose (fat) tissues.

• Vitamin A is essential for vision, immune function, and skin health.

• Vitamin D plays a crucial role in calcium absorption and bone health.

• Vitamin E acts as an antioxidant and helps protect cells from damage.

• Vitamin K is necessary for blood clotting and bone metabolism.

In contrast, the other options provided include a mix of water-soluble vitamins, such as vitamin C and the B vitamins, which do not get stored in the body to the same extent and typically need to be replenished more frequently through diet. This is why the classification provided in option B is the correct identification of fat-soluble vitamins.
