Vitamin D is in the news a lot but, according to a leading researcher, there’s good reason for it. The website, Medscape, interviewed Dr. Cedric Garland, a professor at the University of California San Diego, who has examined the association between vitamin D and disease. Dr. Garland’s research has shown that the risk of all-cause mortality (the risk of dying from any cause) goes up as vitamin D blood levels drop below 30 ng/ml, which is consistent with other scientific work on vitamin D. According to Dr. Garland, every person should aim to have levels above 30 ng/ml. Statistics show that two-thirds of the US population have levels below 30 ng/ml, and therefore need supplementation. If you’re looking to have your levels tested,Dr. Garlandnotes that March is the best time of year to do so, as this is when vitamin D levels are at their lowest.
