Which vitamins are classified as fat-soluble?

The vitamins that are classified as fat-soluble are A, D, E, and K. These vitamins dissolve in fats and oils, which is why they are stored in the body's fatty tissue and liver.

Vitamin A plays a critical role in vision, immune function, and skin health. Vitamin D is essential for calcium absorption and bone health, and it also supports immune function. Vitamin E acts as an antioxidant, protecting cells from damage, while Vitamin K is crucial for blood clotting and bone metabolism.

Fat-soluble vitamins differ from water-soluble vitamins (like the B vitamins and vitamin C), which cannot be stored in the body to the same extent and must be consumed more regularly. This distinction helps clarify the importance of including fat in the diet for the proper absorption of the fat-soluble vitamins.
