Vitamin D and heart disease, diabetes, etc
EngineerGuy posted:
Hi folks,

Here's a fantastic study, showing that deficiency in Vitamin D contributes to heart disease, diabetes, hypertension.

Dr. Fuhrman's advice is best: Get a blood test. Optimal is 35 to 55 ng/ml. A few people do not need any supplement to achieve this range. Most people need 1000 to 2000 IU daily. A few people need much more supplement dose.

Is vitamin D a magic bullet? For a few seriously deficient people, absolutely. For most of us, it is helpful. A few people, with good vitamin D levels without supplements, should not take vitamin D, as it would put them above the optimal range. So stop worrying if vitamin D is a magic bullet or not, and get a blood test. :-)

Relation of Vitamin D Deficiency to Cardiovascular Risk Factors,
Disease Status, and Incident Events in a General
Healthcare Population

Vitamin D recently has been proposed to play an important role in a broad range of organ functions, including cardiovascular (CV) health; however, the CV evidence-base is limited. We prospectively analyzed a large electronic medical records database to determine the prevalence of vitamin D deficiency and the relation of vitamin D levels to prevalent and incident CV risk factors and diseases, including mortality. The database contained 41,504 patient records with at least one measured vitamin D level. The prevalence of vitamin D deficiency (=30 ng/ml) was 63.6%, with only minor differences by gender or age. Vitamin D deficiency was associated with highly significant (p <0.0001) increases in the prevalence of diabetes, hypertension, hyperlipidemia, and peripheral vascular disease. Also, those without risk factors but with severe deficiency had an increased likelihood of developing diabetes, hypertension, and hyperlipidemia. The vitamin D levels were also highly associated with coronary artery disease, myocardial infarction, heart failure, and stroke (all p <0.0001), as well as with incident death, heart failure, coronary artery disease/myocardial infarction (all p <0.0001), stroke (p = 0.003), and their composite (p <0.0001). In conclusion, we have confirmed a high prevalence of vitamin D deficiency in the general healthcare population and an association between vitamin D levels and prevalent and incident CV risk factors and outcomes. These observations lend strong support to the hypothesis that vitamin D might play a primary role in CV risk factors and disease. Given the ease of vitamin D measurement and replacement, prospective studies of vitamin D supplementation to prevent and treat CV disease are urgently needed.

Best regards, EngineerGuy
