Vitamin D Deficiency Doubles Risk of Stroke

Researchers from Johns Hopkins University School of Medicine have found an association between vitamin D deficiency and higher rates of death from heart disease and peripheral artery disease in adults. However, when studying the link more closely, they found that lower blood levels of vitamin D were more greatly associated with stroke in white Americans versus black Americans. Although African Americans suffer from higher rates of stroke and are more likely to be vitamin D deficient, the two do not appear to be statistically related, according to the researchers. They suggest a possible adaptation to vitamin D deficiency, as evidenced by an overall greater bone density. The IOM is reviewing the recommendation for adequate dietary intake of vitamin D.

The results of the study(s) are understated, massively.

The study cited 30 ng/ml, 25 OH, as "sufficient".

This is too low by a factor of at least 2 and does not meet repletion levels in anyone, anywhere.

The natural healthy range of circulating vitamin D is 50-80 ng/ml, 25 OH.

As far as low vitamin D not being a facto with blacks and stroke risk the researchers forgot to state that the number of blacks excluded or DQ'ed because of existing artery/cardiac issues was OFF THE SCALE!
