While you get most vitamins come from plant and animal foods, vitamin D needs something else…Sunshine! And that’s why it’s often called the sunshine vitamin.
When you’re in the sunlight there is a reaction between the protein molecules under your skin and the sunlight. This reaction then produces vitamin D.
But, in the UK, during autumn and winter, the sunlight isn’t strong enough and food may not provide enough of the vitamin. That’s why Public Health England recommend that everyone takes a vitamin D supplement containing 10 micrograms from October to March.
Isn’t it risky to expose your skin to a lot of sunlight?

They also give a useful tip about how to tell whether the sun is high enough in the sky for it absorb into your body.
The tip is to measure your shadow. They say if your shadow is shorter than your height then the sun will produce vitamin D for your body. But, if your shadow is longer than your height, the sun is too low in the sky and can’t produce the vitamin.
