Technically not a "vitamin," vitamin D is in a class by itself. Its metabolic product, calcitriol, is actually a secosteroid hormone that targets over 2000 genes (about 10% of the human genome) in the human body. Current research has implicated vitamin D deficiency as a major factor in the pathology of at least 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more.
Vitamin D's influence on key biological functions vital to one's health and well-being mandates that vitamin D no longer be ignored by the health care industry nor by individuals striving to achieve and maintain a greater state of health.

Death rates surge with inadequate vitamin D
Insufficient levels of serum 25-hydroxyvitamin D (25[OH]D) appear to be a major contributor to deaths in older adults, as shown in a study showing vitamin D levels to be inversely proportional to mortality risk in these individuals (J Am Geriatr Soc. 2009;57:1595-1603).
“The association was strong (two times greater odds of mortality for 25[OH]D level <25.0 nmol/L) and appeared linear within the range of the data and independent of common CVD [cardiovascular disease] and mortality risk factors,” researchers note.
The team looked at the vitamin D levels of 3,408 men and women aged 65 years and older upon their enrollment in the Third National Health and Nutrition Examination Survey (NHANES III). After a median 7.3 years of follow-up, 1,493 (44%) of the cohort had died. Slightly more half the deaths (767) were CVD-related.
Compared with participants who had optimal vitamin D status, those who had low vitamin D levels were three times more likely to die from heart disease and 2.5 times more likely to die from any cause. Individuals with baseline 25(OH)D levels <50.0 nmol/L seemed to be at highest risk for mortality, “but levels of 100.0 nmol/L or greater may be necessary for better survival,” researchers observe.”

232 Toxins Found In Babies
Sunday, January 3, 2010
Laboratory tests commissioned by the Environmental Working Group have detected bisphenol A (BPA), a plastic component and synthetic estrogen, in umbilical cord blood of American infants.
Nine of 10 randomly selected samples of cord blood tested positive for BPA, an industrial petrochemical.
BPA has been implicated in a lengthening list of serious chronic disorders, including cancer, cognitive and behavioral impairments, endocrine system disruption, reproductive and cardiovascular system abnormalities, diabetes, asthma and obesity.
In all, the tests found as many as 232 chemicals in the 10 newborns, all of minority descent. The cord blood study has produced hard new evidence that American children are being exposed, beginning in the womb, to complex mixtures of dangerous substances that may have lifelong consequences.
And in a separate study, researchers found that complications of pregnancy, such as preterm labor, preterm birth, and infection were lowest in women with the highest vitamin D levels.
