Vitamin D. We can get this essential compound by eating vitamin D-rich foods, or by exposing our skin to sunlight.  But most of us don’t have enough of it, and the reasons for this vary. Is it necessary to supplement when we are vitamin D deficient? Is vitamin D deficiency really a sign of poor health?

Researchers are still working to figure out what vitamin D does, how different levels affect our bodies, and what we can do about it. Dr. Manish Ponda, vitamin D expert, discusses the current state of the field and how he uses Big Data to study vitamin D deficiency across large groups.
