Four vitamins — A, D, E, and K — dissolve in fat, not water. That single property shapes how they enter the body, where they are stored, and why too much can build up. Tap each one to explore its role, then use the slider to see why they travel with dietary fat.

One shared trait
Because A, D, E, and K dissolve in fat and not water, the body can store them (mostly in the liver and fatty tissue) rather than flushing the excess in urine. That makes daily intake less urgent — but it also means large supplemental doses of some can accumulate. Water-soluble vitamins rarely behave this way.
