Fat-soluble vitamins A, E, and K dissolve in fat and are transported in the body attached to lipids and require pancreatic enzymes and bile for absorption. They are stored in the liver and fatty tissue, which is why an excess concentration of fat-soluble vitamins can be toxic. When blood concentrations of fat-soluble vitamins decline, the body simply retrieves them from storage. Individuals with pancreatic insufficiency, cirrhosis or malabsorption syndrome may have low concentrations of fat-soluble vitamins. Consuming sources of fat-soluble vitamins daily is not necessary, but average intake of these vitamins consumed over time is beneficial. The impact of these fat-soluble vitamins in the management of wounds and other conditions will be discussed.
