Which vitamin is fat-soluble and stored in body fat?

Explanation:
Vitamins are grouped by solubility, which shapes how they are absorbed, transported, stored, and excreted. Fat-soluble vitamins are absorbed with fats and can be stored in body tissues, especially the liver and fat stores, providing a reserve that can last for weeks to months. This storage means they can accumulate if taken in excess. Vitamin A fits this pattern. It is fat-soluble and is stored primarily in the liver and fat tissue, allowing the body to draw on its stores when intake is low. This storage also means there is a potential for toxicity if intake from supplements is too high over time. In contrast, vitamin C and the B vitamins are water-soluble and not stored to the same degree in fat tissue. They are generally excreted in urine when consumed in excess, or stored in limited amounts (with B12 stored in the liver but not in fat). So, the vitamin that is fat-soluble and stored in body fat is vitamin A.
