What is Vitamin D?
Vitamin D is important for good overall health and strong and healthy bones. It’s also an important factor in making sure your muscles, heart, lungs and brain work well and that your body can fight infection.
Your body can make its own vitamin D from sunlight or UV tanning. You can also get vitamin D from supplements and a very small amount comes from a few foods you eat.
The vitamin D that you get in your skin from sunlight or UV tanning, and the vitamin D from supplements, has to be changed by your body a number of times before it can be used. Once it’s ready, your body uses it to manage the amount of calcium in your blood, bones and gut and to help cells all over your body to communicate properly.
What does Vitamin D do?
Vitamins are chemicals that are needed by your body for good health. They are vital for everyone and ensure that your body works well, is able to fight illness and heal well.
Vitamin D isn’t like most other vitamins. Your body can make its own vitamin D when you expose your skin to sunlight or UV tanning.
Getting the right amount of vitamin D doesn’t depend on the foods you eat. To get enough vitamin D you need to expose your skin to sunlight or UV tanning regularly.
