How much vitamin D do we need and how can we get it?

Healthy people who spend enough time outdoors don’t need to worry about not getting enough vitamin D. Those who have a higher risk of developing a vitamin D deficiency can take supplements.
Vitamin D is important for healthy bones. It helps bones to absorb minerals that make them strong. Our bodies can usually produce the vitamin D they need themselves. All it takes is a few minutes of sunlight on our skin. We also get a small amount of vitamin D through our food.
So you don’t need to have your vitamin D levels checked regularly. There’s no health benefit unless there’s a specific reason to get them checked.
