(NaturalNews) Severe vitamin D deficiency influences heart health: study
Mainstream medicine has promoted the merits of vitamin D's bone health and rickets prevention for decades. For that level of health protection, a low RDA (recommended dietary allowance) was established of 600 iu (international units) daily while a vitamin D blood level at 20 ng/ml (nanograms/milliliter) was considered normal.
Now most real vitamin D experts agree that the minimum 25(OH)D serum level for optimum health and immunity from disease should start at 50 ng/ml. With these recent discoveries, many are taking four to ten thousand
iu of vitamin D3 supplements daily, unless they're under the sun relatively bare-skinned and often.
A few courageous heart specialist MDs are breaking through the cholesterol smoke screen scam asserting that arterial inflammation is the root of all cardiovascular issues and heart disease (http://www.naturalnews.com
A lot of this inflammation is the result of poor diets. But vitamin D also provides a measure of protection against inflammation of all types (http://www.naturalnews.com
With the link of inflammation to heart disease, it's no wonder that recent studies are pointing to increased heart disease mortality among those vitamin D deficient.
Studies connecting vitamin D deficiency to increased heart disease
These studies were conducted on patients in hospitals and clinics that handle coronary problems. The most recent was conducted in Brazil at and published in PubMed online in November of 2012. (Sources   below)
Two-hundred and six patients admitted into two nearby hospitals with various acute heart
conditions had their blood serum vitamin D levels measured upon admission.
They were divided into two groups: Those with serum D levels at or under 10 ng/ml, considered severely deficient, and those with 20 +/- 8 ng/ml, closer to normal. A higher percentage of those patients severely deficient died in the hospital than those mildly deficient.
The researchers concluded, "... severe vitamin D deficiency
is independently associated with in-hospital cardiovascular mortality in patients with acute coronary syndromes." In other words, your chances of dying in a hospital after a heart attack are greater if you're vitamin D deficient.
In September of 2012, Science Daily
reported a Danish study conducted by the University of Copenhagen
and the Copenhagen University Hospital
. This study involved more than 10,000 Danes whose vitamin D levels were established between 1981 and 1983 and tested again with follow-up readings since then.
Lead researcher Dr. Peter Brondum-Jacobsen reported: "We have observed low levels of vitamin D compared to optimal levels are linked to 40% higher risk of ischemic heart disease
[reduced blood supply], 64% higher risk of heart attack, 57% higher risk of early death, and no less than 81% higher risk of death from heart disease." (Source  below)
Another study reported by Science Daily
in 2009 took place at the Heart Institute at Intermountain Medical Center
in Salt Lake City, Utah (USA). This time almost 28,000 patients of 50 years or older age with no prior history of heart disease had their vitamin D blood levels measured periodically.
The levels were divided into very low, low, and normal. This time the normal standard was relatively high at 30 ng/ml. They found that those with very low levels of vitamin D were twice as likely to have heart failure than those with normal levels.
Comparing very low D levels to normal, the low end patients were 78 percent more prone to strokes and 45 percent more likely to incur coronary artery disease. Overall, very low levels of vitamin D appeared to manifest twice as much heart failure as normal D levels. (Source  below)
It's impossible to overdose vitamin D from sun exposure. But it's remotely possible that supplementing heavily over time with D3 might even create heart problems. This can be avoided by also taking vitamin K2, especially the MK-7 variety (http://www.naturalnews.com/027832_vitamin_K_osteoporosis.html
