The Vitamin D Newsletter

How much calcium do we need and does excess cause harm? This Vitamin D newsletter is always reviewing the latest information. It is worth reading the research on Calcium.
We all get about 800 mg from our average diet and we get about 1400 mg of phosphorus so I give enough calcium (500 mg) in Beyond Any Multiple and in Beyond Chelation-Improved to avoid SECONDARY HYPERPARATHYROIDISM. Also I insist on giving 500 mg of Magnesium (with B-6) to help tame the calcium (i.e. a calcium channel blocker effect) whenever I give any calcium, which is almost never more than the 500 mg in BAM.
Of course, with the research on vitamin D we almost all need more than we get and with the fact that we are all living longer, who wants calcified vascular tissues and resulting hypertension, so we also need K-2.

Quest Diagnostics and Cardiovascular Disease
This is a periodic newsletter from the Vitamin D Council, a non-profit trying to end the epidemic of vitamin D deficiency. If you want to unsubscribe, go to the end of this newsletter. If you are not subscribed, you can do so on the Vitamin D Council’s website.
The Annals of Internal Medicine published two important reviews this month. In the first review, Dr. Anastassios Pittas and colleagues from Tufts University reviewed 106 articles and combined the 32 quality studies, a meta-analysis, looking at “cardiometabolic” outcomes such as diabetes, hypertension and cardiovascular disease. Their conclusion: “Lower vitamin D status seems to be associated with increased risk for hypertension and cardiovascular disease, but we do not yet know whether vitamin D supplements will affect clinical outcomes.” Read on.Pittas AG, et al. Systematic review: Vitamin D and cardiometabolic outcomes. Ann Intern Med. 2010 Mar 2;152(5):307-14.
The second Annals of Internal Medicine review, by Dr. Lu Wang and colleagues at Harvard, looked at studies of vitamin D supplementation and found two randomized placebo controlled trials to combine. Dozens of different types of studies have looked at vitamin D and cardiovascular outcomes. The latitude studies are clear, the closer you live to the equator, the less cardiovascular disease. The dietary studies are mixed, because vitamin D is not contained in the diet, at least in significant amounts. The epidemiological studies are clear.Wang L, et al. Systematic review: Vitamin D and calcium supplementation in prevention of cardiovascular events. Ann Intern Med. 2010 Mar 2;152(5):315-23.
Dr. Wang concluded, “To date, evidence from prospective observational studies and randomized controlled trials suggests that vitamin D supplementation at moderate to high doses may have beneficial effects on reducing the risk for cardiovascular disease.”
About the same time that the two above meta-analyses were published, Dr. Brent Muhlestein, director of cardiovascular research at the Intermountain Medical Center Heart Institute in Murray, Utah, presented a paper at this year’s American College of Cardiology’s annual scientific session in Atlanta.
