What are the fat-soluble vitamins?

Fat-soluble vitamins are those that dissolve in fats and oils, and they can be stored in the body's fatty tissue and liver, which allows them to enter the bloodstream when needed. The vitamins classified as fat-soluble include vitamins A, D, E, and K.

Vitamin A plays a crucial role in vision, immune function, and skin health. Vitamin D is essential for calcium absorption and bone health. Vitamin E serves as an antioxidant, helping to protect cells from damage, and vitamin K is vital for blood clotting and bone metabolism. This classification is significant in nutrition since fat-soluble vitamins require dietary fats for absorption, and excessive intake can lead to toxicity due to their ability to be stored in the body.

Understanding which vitamins are fat-soluble helps in planning diets and avoiding deficiencies or toxicities associated with these nutrients.
