Where in the body are fat-soluble vitamins stored?

1. Muscle

2. Liver

3. Intestines

4. Fat tissue

The correct answer is: Liver

Fat-soluble vitamins are primarily stored in the liver. These vitamins, which include A, D, E, and K, are absorbed through the intestinal tract along with dietary fats. The liver plays a crucial role in the metabolism and storage of these vitamins, allowing the body to access them when needed. Although fat tissues also play a role in storing these vitamins, the liver serves as the main storage site where they can be regulated and mobilized as the body requires them. The liver's ability to store these vitamins ensures that the body has a reserve available for functions such as vision, immune response, bone health, and antioxidant activity. While muscles and intestines are involved in other metabolic processes, they do not serve as significant storage sites for fat-soluble vitamins.
