Which category do vitamins A, D, E, and K belong to?

Vitamins A, D, E, and K are categorized as fat-soluble vitamins because they have specific characteristics that are distinct from water-soluble vitamins. Fat-soluble vitamins dissolve in fats and oils, which allows them to be stored in the body's fatty tissues and liver. This storage capability enables the body to draw on these vitamins when needed, unlike water-soluble vitamins, which must be consumed more frequently due to their inability to be stored effectively. The absorption of fat-soluble vitamins occurs alongside dietary fat, making dietary fat an important factor in their utilization. This classification also highlights their vital roles in various physiological functions, such as vision, immunity, blood clotting, and bone health. Understanding the characteristics of these vitamins enables better dietary planning and health management.
