Vitamin D: Are you getting enough?

 

Vitamin D is an essential fat-soluble vitamin. It’s sometimes called the “sunshine vitamin” because our skin makes it when exposed to the sun.

It’s also the most common nutrient deficiency!

Like most vitamins, vitamin D has many functions in the body. It’s mostly known for its ability to help build strong bones. But, vitamin D is also important for a healthy immune system, digestive system, heart and mental health, blood sugar regulation, fertility, and resistance to cancer.

FUN FACT: Vitamin D is the vitamin with more scientific articles published since 2000 than any other vitamin.

Let’s talk about the many roles vitamin D has in promoting good health. We’ll also go over the different forms of vitamin D and what exactly is a deficiency. Finally, I’ll give you three sources of this critical nutrient and how much we should get.

Make sure you’re getting enough!
