It is important to note that too much Vitamin D (and Vitamin A) can be toxic 
and cause kidney damage and other serious problems.

If you take megadoses of Vit D, (50,000+ IU/day)  you MUST be under the care 
of a physician and you MUST have your levels of Vit D tested regularly until 
you determine the correct dosage for your body; also considering other 
factors such as skin type, amount of direct sunlight, diet, etc.

The blood test is called 25-hydroxy vitamin D.

Overdosage:  From www.pdrhealth.com
Hypercalcemia can result either from excess intakes of prescribed forms of 
vitamin D or from consumption of high amounts of vitamin D2 or vitamin D3. 
The hypercalcemia associated with hypervitaminosis D may cause multiple 
debilitating effects. Anorexia, nausea and vomiting have been observed in 
hypercalcemic individuals treated with 1,250 to 5,000 micrograms (50,000 to 
200,000 IU)/day of vitamin D. Hypercalcemia can result in a loss of the 
urinary concentrating mechanism of the kidney tubule, resulting in polyuria 
and polydipsia. The prolonged ingestion of excessive amounts of vitamin D 
and the accompanying hypercalcemia can result in metastatic calcification of 
soft tissues, including the kidney, blood vessels, heart and lungs. 
Typically, chronic ingestion of 50,000 to 100,000 IU/day of vitamin D is 
required to produce hypercalcemia. Since vitamin D stores in fat may be 
substantial, vitamin D intoxication may persist for weeks after vitamin D 
ingestion is terminated. The elimination half-life of vitamin D is about 20 
to 29 days.
