lipid-soluble
Absorbed through oils
Lipid-soluble describes substances that dissolve in fats and oils rather than water.
Vitamins A, D, E, and K are lipid-soluble, meaning they're absorbed with dietary fats and can accumulate in body tissues.
The term appears in nutrition, pharmacology, and chemistry: Lipid-soluble drugs cross the blood-brain barrier more easily.
Also called fat-soluble.
