Vitamin D research: What primary care physicians need to know

According to the NIH, vitamin D is only naturally present in a few foods. While it is most abundant in fatty fish and fish liver oils, smaller amounts can also be found cheese, egg yolks and beef liver. It can also be consumed through supplements, other foods and sunlight.

The small number of direct vitamin D sources doesn’t necessarily mean this nutrient can’t have large impacts on the body and brain. Healio Family Medicine compiled some of the latest research on vitamin D that may be relevant to your practice. Here’s what you need to know.
