While Vitamin D supplements side effects are generally negligible in comparison to the benefits it’s possible that a simple pill may not be enough to stave off heart disease when compared to getting a little sunshine.
In a related report by The Inquisitr, some studies suggest that Vitamin D supplements are a waste of time and doctors were unable to conclude that vitamin D supplements increased life expectancy in the general population by more than 5 percent:
“Lots of observational studies that measure vitamin D levels at baseline and compare health outcomes over time between groups with high levels and low levels have reported associations between low vitamin D levels and poor health outcomes. These studies are not able to determine causality because of their design. The problem with those studies is that you can’t determine whether there’s a cause and effect. Groups with low levels of vitamin D tend to be older, heavier, tend to exercise less and spend less time outside.”
But vitamin D deficiency was also found in 70 percent of patients whose blood flow through the arteries were checked via a coronary angiography, which is an imaging test. Studies have shown that people with vitamin D deficiency tend to have a 32 percent higher chance of heart disease. There were also 20 percent more severe cases with those having less vitamin D. Worse, the patients with the lowest levels of the vital nutrient tended to have double the rate for clogged arteries when compared to patients with normal levels of vitamin D.
So what can be done? Cardiologist Dr Monica Verdoia, of Eastern Piedmont University in Novara, Italy, suggests eating foods rich in vitamin D and exercising. She also says it’s uncertain whether vitamin D supplements are worthwhile:
“Present results suggest vitamin D deficiency to be the cause rather than the consequence of hardening of the arteries. Although evidence of benefits with vitamin D supplementation in cardiovascular outcomes are still lacking, strategies to raise natural vitamin D should probably be advised in the prevention of cardiovascular disease.”
Doctor Muhammad Amer, who led another study on vitamin D supplements, says otherwise healthy people should watch their dosage levels because of the risk of side effects:
“Healthy people have been popping these pills, but they should not continue taking vitamin D supplements unchecked. At a certain point, more vitamin D no longer confers any survival benefit, so taking these expensive supplements is at best a waste of money.”
Do you rely on using vitamin D supplements? If so, what do you think of these studies?
