- Vitamin D does a lot of heavylifting in your body: It helps out with everything from bone support to immune health and muscle function.
- Unfortunately, most Americans struggle to get enough vitamin D from sunlight and diet alone. Learn which factors might put you at risk for low levels of vitamin D—and how you can make sure you're getting enough.
Vitamin D’s sunny reputation is well-deserved, and not just because logging time outside can be a great way to boost your levels. D plays a role in supporting immune health and muscle function, and it’s also a pretty great team player when it comes to bone health: Vitamin D helps to assist the absorption of calcium you’re consuming through your diet, and works to help out with the maintenance of your bones .
The only downside to this important nutrient? It can be really tricky for many of us to get enough vitamin D—in fact, some researchers estimate that as many as 75% of Americans don't get enough from sun and diet alone.That’s because a lot of factors can get in the way of us meeting our needs, from SPF and general lack of sun exposure to where we choose to live.
That said, knowing the factors that might contribute to vitamin D shortfalls is a great first step towards understanding your own needs and ultimately getting your vitamin D levels to a good place. (Spoiler: For most of us, finding a great vitamin D supplement or better yet, a multivitamin that includes vitamin D is the way to go.)
