Which vitamins belong to the group that is stored in the body's fatty tissues and can be toxic in excess?

Fat-soluble vitamins are the ones that are stored in the body's fatty tissues and can be toxic when consumed in excess. This group includes vitamins A, D, E, and K. Unlike water-soluble vitamins, which are not stored in large amounts and are excreted through urine, fat-soluble vitamins accumulate in the liver and fat tissues. Because of this storage capability, if these vitamins are taken in much higher amounts than the body needs, it can lead to toxicity, which is a concern for overall health.

Micronutrients, while they encompass both vitamins and minerals, do not specifically address the storage issue and potential toxicity associated with fat-soluble vitamins. Essential vitamins refers to vitamins that are crucial for various bodily functions but does not infer anything about their solubility or storage. Water-soluble vitamins, as mentioned earlier, do not pose the same risk for toxicity due to their excretion through urine and lack of significant storage in the body. Thus, fat-soluble vitamins are correctly identified as the vitamins that have the potential for toxicity when consumed in excessive amounts.
