Shedding light on vitamin D and your immune system

Thinking Nutrition

Vitamin D is well-known for its role in building strong bones. But increasingly, research is revealing the importance of vitamin D in protecting against a host of health problems. Serving a dual role as both a hormone and vitamin, it is the sun that is the main source of vitamin D with few foods being reliable sources of it. In this podcast, I outline the key roles played by vitamin D, profile the growing number of health areas linked to it especially as it relates to immunity, and discuss how you can keep your vitamin D levels up. That last point is especially important in today’s times with self-isolation now trending as 2020’s word of the year.
