Which vitamins are primarily stored in the liver?

The vitamins primarily stored in the liver include A, D, E, K, and B12. The liver acts as a central storage site for fat-soluble vitamins, which are essential for various body functions.

Vitamin A is crucial for vision, immune function, and skin health. Vitamin D is vital for calcium absorption and bone health, while Vitamin E acts as an antioxidant, protecting cells from damage. Vitamin K plays a key role in blood clotting processes. Vitamin B12, although water-soluble, is unique in that it can be stored in significant amounts in the liver, which is important for nerve health and red blood cell production.

The other options include vitamins that are either not stored in the liver in significant quantities or are predominantly water-soluble, which means they are usually excreted if taken in excess and not retained in the body’s tissues like fat-soluble vitamins.
