Which vitamins are fat-soluble and can be stored in the body?

The vitamins that are classified as fat-soluble are A, D, E, and K. These vitamins are soluble in fats and oils and are absorbed into the body along with dietary fat. Once absorbed, they can be stored in the liver and fatty tissues for later use, which distinguishes them from water-soluble vitamins that must be consumed more regularly since they are not stored to the same extent and are excreted through urine.

Vitamin A plays an essential role in vision, immune function, and skin health. Vitamin D is crucial for calcium absorption and bone health. Vitamin E acts as an antioxidant, helping to protect cells from damage, while Vitamin K is vital for proper blood clotting and bone metabolism. The body’s ability to store these vitamins means they can be utilized as needed, but it can also lead to toxicity if consumed in excessive amounts since they are not easily excreted.

Other choices that include water-soluble vitamins, such as B and C, do not fit the criteria for fat-soluble vitamins as they are not stored in the body in the same way, thus making those options incorrect.
