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.
