Taking vitamin D supplements does not prevent heart attack, stroke, heart disease or death from cardiovascular problems, a new study suggests.
Through the years, scientists have linked vitamin D deficiency to a broad spectrum of health problems, including everything from diabetes to brittle bones, heart problems, depression and more.
And on the heels of this research, vitamin D supplement sales have soared.
But a new University of Michigan study of 8,000 people calls the notion that the supplements will protect your heart into question, finding that those who took the capsules were no less at-risk than people taking a placebo.
Vitamin D is one of the most popular supplements in the US, but a new study found it does no more to prevent heart attacks than placebos do
Research has suggested that as many as 40 percent of men and 50 percent of women in the US have suboptimal vitamin D levels, and a quarter of us have severe deficiencies.
And it's spurred a widespread scramble to boost levels of the sunshine vitamin - and the growth of a market estimated to be worth anywhere from $1.7 to $3.3 billion by 2025 (predictions vary wildly).
