Which of the following are considered fat-soluble vitamins?

Fat-soluble vitamins are those that can be stored in the body's fatty tissues and liver. They are absorbed along with dietary fat and generally remain in the body for longer periods compared to water-soluble vitamins. The fat-soluble vitamins include A, D, E, and K.

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, protecting cells from damage. Vitamin K is important for blood clotting and bone metabolism.

In this context, the recognition of A, D, E, and K as fat-soluble vitamins is critical for understanding dietary needs and supplementation in various populations. Other vitamins, such as those in the B and C groups, are water-soluble and do not share the same storage capabilities or absorption mechanisms. Consequently, the inclusion of A, D, E, and K as fat-soluble vitamins highlights their unique roles in nutrition and physiology.
