fat-soluble

Absorbed with lipids

Fat-soluble describes substances that dissolve in fats and oils rather than water.

The term appears most often with vitamins: vitamins A, D, E, and K are fat-soluble, meaning the body absorbs them along with dietary fats and stores them in fatty tissue.

Fat-soluble vitamins can accumulate to toxic levels if taken in excess.
