Context The human body requires vitamins in small amounts for various functions, from energy production to immune support. However, consuming excessive amounts of certain vitamins can lead to a condition known as vitamin toxicity, or hypervitaminosis. This occurs when the level of a vitamin in the body becomes so high that it interferes with normal physiological processes, potentially causing adverse health effects. Fat-soluble vitamins like A, D, E, and K are more likely to cause toxicity than water-soluble vitamins like vitamin C and B vitamins because they can accumulate in the body's tissues. Understanding how vitamins can reach toxic levels and the mechanisms by which they cause harm is essential for maintaining optimal health and avoiding potential health risks. Simple Answer Your body needs vitamins to work, but too much of some can be harmful. Fat-soluble vitamins (A, D, E, K) are stored in your body and can build up.

While it's often associated with sunlight exposure, it can also be obtained through dietary sources and supplements. The connection between these two methods lies in the chemical process involved in producing Vitamin D in our bodies....
