Post by unknownIn fact only 2 or 3 of the many forms of cancer have been shown to be
reduced at any significant level with use of vit. d.
Note that it is decreased risk only, not absolute prevention nor "cure".

Men with higher vitamin D blood levels are at
increased risk of developing prostate cancer.

An excess of vitamin D causes abnormally high blood
concentrations of calcium, which can cause
overcalcification of the bones, soft tissues, heart
and kidneys. In addition, hypertension can result.

Complex regulatory mechanisms control metabolism.
Recent epidemiologic evidence suggests that there is
a narrow range of vitamin D levels in which vascular
function is optimized. Levels above or below this
natural homeostasis of vitamin D increase mortality.
Overall, excess or deficiency in the
calcipherol system appear to cause abnormal
functioning and premature aging. >>
