Recommended vitamin D intake is 200 international units a day up to age 50, 400 units for ages 50 to 70, and 600 units a day over the age of 70.
One way to reach that level is to pop a supplement, O'Keefe said. "There is strong evidence that supplementing vitamin D improves health."

"This is an important report," said Robert U. Simpson, a professor of pharmacology at the University of Michigan, whose group was the first to identify vitamin D receptors in heart cells. "It will help those interested in cardiovascular disease understand more about the vitamin D system."
Vitamin D is not just another vitamin, Simpson said. "It is a precursor to a hormone, and this prehormone is responsible for making a very important regulator of cardiovascular processes," he said.
Supplementation is an acceptable way of getting enough vitamin D, Simpson added. "Food is not really an option," Simpson said. "You don't get enough vitamin D in the foods we ordinarily eat. Supplementation is my preferred choice, although I get sunlight whenever the sun shines here in Ann Arbor."
