How much vitamin D do we need to maintain health? This is not an easy question to answer because a debate exists in the scientific evidence about the recommended daily intake. Not long ago, vitamin D was primarily viewed as a nutrient needed for bone health. In recent years, countless studies have suggested it plays a role in a multitude of other chronic conditions, including cancer, cardiovascular, and autoimmune diseases. In addition, a growing number of people have been identified as vitamin D deficient. This module presents the latest evidence for intake levels higher than the dietary reference intake, risk factors for vitamin D deficiency, and ways to treat a deficiency with supplementation.


The goal of this program is to provide healthcare professionals with guidelines for improving the vitamin D status of their patients. After studying the information presented here, you will be able to:
  • Identify population groups at greatest risk for vitamin D deficiency.
  • List factors that affect vitamin D status.
  • Recommend dietary and lifestyle strategies to help specific populations meet their vitamin D needs.
  • Describe research-based evidence for vitamin D’s potential role in preventing or ameliorating chronic disease.
