The liver stores approximately 80% of the body's total vitamin A content, with a precise mechanism for mobilization involving retinol-binding protein (RBP). This vital process is essential for distributing vitamin A from the liver to peripheral tissues, where it is used for critical functions like vision and reproduction.

According to the World Health Organization, millions of children suffer from vitamin A deficiency globally, highlighting the importance of its efficient delivery throughout the body. The crucial protein responsible for the systemic transport of this vital nutrient is the retinol-binding protein (RBP), ensuring that vitamin A reaches the tissues that need it most.

Over 70% of the body's total vitamin A reserves are stored in the liver, serving as a critical buffer against dietary inconsistencies. The complex system governing the storage and transport of vitamin A ensures a stable supply of this essential fat-soluble nutrient to all tissues for vision, immune function, and gene regulation.

The liver stores approximately 70% of the body's total vitamin A reserves. From this hepatic storage, a specific protein carries vitamin A, specifically retinol, through the bloodstream to prevent its degradation and deliver it efficiently to other tissues.

In humans, approximately 70% of the body's vitamin A reserves are stored in the liver. The vital role of the retinol-binding protein is to mobilize and transport this stored vitamin A, known as retinol, from the liver to peripheral tissues, ensuring a steady supply for critical physiological processes.
