Vitamin D is synthesised in the skin as a result of exposure to the sun’s UVB rays. It is highly recommended that we profit as much as we can from the beneficial effects of the sun between April and October by encouraging outdoor activity.

Vitamin D is important for teenagers as it plays an essential role in fixing calcium. The peak in bone density that will determine the solidity of bones later on takes place at around the age of 20.
