Sunshine, not food, is where most of your vitamin D comes from. So even a healthy and well balanced diet, that provides all the other vitamins and nutrients, is unlikely to provide enough vitamin D. To get enough vitamin D you need to spend some time outside with some bare skin on most days during the summer months.
How is vitamin D different to other nutrients?
You make vitamin D under your skin when you are outside in daylight, which is the reason vitamin D is sometimes called the sunshine vitamin. By definition, a vitamin is a nutrient that we cannot make in our body. Vitamin D is actually a hormone rather than a vitamin. Very few foods contain vitamin D naturally.
What does vitamin D do in your body?
Vitamin D makes sure you absorb enough calcium for your bones and teeth. Even if you have a calcium-rich diet, without enough vitamin D you cannot absorb calcium into the body. Its importance as a hormone is also being recognised. It helps maintain a healthy immune system and reduces the risk of some forms of cancer. Population studies suggest that lack of vitamin D may increase the risk of chronic health conditions such as multiple sclerosis.
