Vitamins A, D, and K are fat-soluble vitamins, which means they are absorbed, stored, and transported in the body with the help of dietary fat. These vitamins are primarily stored in the liver and adipose (fat) tissue.

The liver plays a central role in storing and regulating these fat-soluble vitamins. It stores significant amounts of vitamin A (retinol) and synthesizes some of the active forms of vitamin D. Additionally, the liver stores vitamin K, which is crucial for blood clotting and bone health.

When the body needs these vitamins, it can release them from storage in the liver and fat tissue to support various functions, such as vision, bone health, and blood clotting. It’s important to maintain a balanced diet to ensure an adequate intake of these vitamins and prevent deficiencies.
