Tag: Retinoid metabolism

Unlike water-soluble vitamins, which are easily flushed from the body, fat-soluble vitamin A is stored in the liver and metabolized through a complex process. This sophisticated system dictates how is vitamin A removed from the body to prevent toxic accumulation, a function critical for overall health.

The liver stores approximately 80% of the body's total vitamin A reserves. This critical function is performed by specialized liver cells, known as hepatic stellate cells, which are what are vitamin A storing cells in the liver. These remarkable cells manage the body's retinoid supply and undergo a dramatic transformation during liver injury.
