Which minerals are primarily stored in the liver?

The liver plays a vital role in the storage of various nutrients, particularly certain vitamins and minerals that are essential for various bodily functions. Among the options listed, the storage of Vitamins A, D, K, and B12 in the liver is particularly significant.

Vitamin A is stored in the liver and is crucial for vision, immune function, and skin health. Vitamin D is important for calcium metabolism and skeletal health, while Vitamin K is key for blood coagulation processes. Vitamin B12, essential for red blood cell formation and neurological function, is also stored in the liver, which helps maintain adequate levels in the body.

In contrast, calcium and iron are typically stored in bones and the spleen/marrow, respectively. Sodium and potassium primarily function in fluid balance and nerve signaling, and while they are found in the body, they are not specifically stored in the liver. Similarly, magnesium and zinc serve numerous metabolic functions in various tissues but are not predominantly stored in the liver. The liver’s unique capacity to store specific fat-soluble vitamins and the water-soluble Vitamin B12 is what makes this option the correct choice.
