Vitamin D

An example of the benefits of moderation, both an excess and a deficiency of vitamin D can be hazardous to one’s health. Prolonged exposures to high levels of vitamin D, sometimes termed hypervitaminosis D, can often be diagnosed through observation of small, yellowish colored patches on the skin and in the eyes, and is further characterized by fatigue, decrease in appetite, muscle weakness, nausea, and vomiting. Also, since calcium absorption is affected by the vitamin, hypercalcemia, or an overabundance of calcium in the blood, may occur. Contrariwise, the lack of sufficient quantities of vitamin D in the body is most commonly associated with rickets and osteomalacia, both of which are characterized by serious problems with the bones.
