NEW YORK (Reuters Health) – Taking vitamin D supplements does not prevent heart attacks, stroke or cardiovascular disease, a new study suggests.
Over the years, scientists have linked vitamin D deficiency to a wide range of health problems, including diabetes, osteoporosis, heart problems and depression, among others.
But the Michigan State University study of 80,000 participants puts the idea that dietary supplements will protect your heart in question. I found those who took supplemental tablets were not at least as vulnerable as those who took placebo.
Despite the many studies that have found a link between low levels of vitamin D and poor heart health, there is little evidence that vitamin D deficiency causes heart disease, or that getting enough of it can prevent it.
So, the researchers decided to test this by analyzing 21 previous experiences of vitamin D. It was found that taking vitamin D supplements did not prevent injury to participants heart attacks and stroke.
The study does not attempt to explain exactly what is happening, as the researchers presented some theories in a paper accompanying the study, and pointed out that the main source of vitamin D is the sun, which most people get by walking outside the house.
While vitamin D is important for bone health, there is a clearer and causal relationship between active lifestyle and heart health. Low levels of vitamin D only referred to "lack of physical activity and therefore a sign of deterioration in overall health," the study said.
The results of the new study "support efforts to curb waste in spending on vitamin D tests and treatments in populations not at risk of deficiency or to prevent deaths from heart disease," the researchers write. At the same time, this does not mean we should give up vitamin D completely, especially for kidney patients and hypothyroidism.
