Fat-soluble vitamins differ from water-soluble vitamins in that they can accumulate in the body and cause toxicity due to their ability to dissolve in fats and oils.

Fat-soluble vitamins include vitamins A, D, E, and K.
They are absorbed with the help of bile salts and fats in the small intestine.
These vitamins are transported in the body by binding to lipoproteins or chylomicrons.
The main function of fat-soluble vitamins is to facilitate various physiological processes, such as cell growth, bone development, and antioxidant activities.

Fat-soluble vitamins require bile salts and dietary fats for absorption in the small intestine.
Malabsorption of fat can lead to deficiencies in fat-soluble vitamins.

Fat-soluble vitamins are not excreted in urine like water-soluble vitamins, but rather stored in adipose tissue and liver.
Excess fat-soluble vitamins can be stored for long periods, which increases the risk of toxicity.
