Fat-soluble vitamins are absorbed with dietary fats and stored in the body's tissues, especially in the liver and adipose tissue. Their absorption depends on bile to emulsify fats, and after absorption they travel via chylomicrons through the lymphatic system. Because they can be stored, they stay in the body longer and can accumulate if taken in excess, raising the potential for toxicity.

Among the vitamins, the fat-soluble group includes vitamins A, D, E, and K. In contrast, vitamins C and the B vitamins are water-soluble, not stored to the same extent, and are excreted in urine, requiring more regular intake to prevent deficiency.
