There is a strong association of sunlight exposure and increased blood levels of vitamin D with a decreased risk of many common cancers: colon, breast, prostate, ovarian.Īdditionally, vitamin D deficiency has been associated with an increased risk for Type 1 diabetes.

Moreover, there is evidence that vitamin D may have subtle but profound effects on regulating cell growth and on our cardiovascular and immune systems. Vitamin D deficiency can precipitate and exacerbate osteoporosis. Without enough of it, a child can get rickets, and an adult might suffer bone softening, a mineralization defect. The vitamin plays a crucial role in most metabolic functions and also, muscle, cardiac and neurological functions. However, this vitamin is critically important for maintaining normal calcium in the blood and for bone health. I would say vitamin D has been taken for granted and, as a result, has been ignored. Would you describe vitamin D as an underrated vitamin?Ī.

His research into the way skin converts sunlight into vitamin D has led him to a new crusade, encouraging people to let some sun shine on their skin and, thus, some vitamin D into their systems, a controversial idea in some corners of the dermatology world. His psoriasis finding, he notes, has become a widely employed therapy in treating some forms of the disorder. His proudest accomplishments, he says, include discoveries that show how activated vitamin D can be used to treat osteoporosis, kidney failure and psoriasis. Holick has spent 30 years researching the many ways that vitamin D serves the creatures of this planet. Holick - a 56-year-old endocrinologist and a professor of dermatology, biophysics and physiology - handed a reporter a copy of a paper he had recently written, ''Vitamin D: The Underappreciated D-lightful Hormone That Is Important for Skeletal and Cellular Health,'' published in the journal Current Opinions in Endocrinology and Diabetes.ĭr. ''The important fact I learned from you yesterday is that most living things or persons need vitamin D,'' one child wrote.Īnother added, ''Even frogs need vitamin D.'' On the office walls are letters from sixth graders responding to a talk he gave. Holick in the Boston University Medical Center quickly conveys his enthusiasm for his favorite hormone, vitamin D. But, as always, if you’re concerned about your bone health, check in with your primary care provider to make sure you’re doing everything possible to stay healthy, and to see if vitamin D supplements could help.A visit to the office of Dr. In short, if you’re worried about your vitamin D levels, you might want to consider spending the recommended amount of time in the sun and adding more fatty fish to your diet before adding another supplement to your daily medicine routine. “Vitamin D testing is not necessary for most people, and that’s because there really isn’t a reliable test or acceptable reference range-that’s why it seems like everyone these days has a low vitamin D level,” says Dr.

And even if you do get tested, the results might not be accurate. “Unless there are specific reasons for concern, there’s not general recommendation for testing and screening,” says Dr. Many people get their blood tested for having a vitamin D deficiency, but that’s not always a necessity. Some people also turn to supplements to increase their vitamin D intake, but whether that’s necessary for most people “is a big area of controversy in medicine,” says Dr. (FYI: IU stands for international units, which is what vitamin D is measured in, rather than grams or milligrams.) Luckily, there are plenty of (easy) ways to get the recommended amount each day-here's how. Ford says.As far as a daily dosage of vitamin D goes, “the Institute of Medicine recommends 600-1000 IU of Vitamin D daily to meet 95% of the populations’ needs,” says Tania Elliott, MD, an instructor of clinical medicine at NYU Langone. Vitamin D can also help prevent against osteoporosis, which makes your bones brittle, and a vitamin D deficiency can contribute to a “gradual loss of strength of bones over time,” Dr.

That's vitamin D's job-without it, the calcium you get from yogurt, cheese, and even vegetables like broccoli wouldn't get absorbed, and ultimately wouldn't do much in terms of keeping your bones strong. Calcium gets most of the credit for maintaining strong, healthy bones, but vitamin D is also a key player in bone health."You can have all the calcium in the world, it doesn’t get absorbed into your bones" without vitamin D, Donald Ford, MD, a family medicine physician at Cleveland Clinic, tells Health.
