Skin exposure to sunlight is the primary source of vitamin D
Vitamin D is made by the body on skin exposure to UV light, it is the primary source of vitamin D as it's nearly impossible to get enough from food sources alone. However, UV rays are also a major cause of skin cancer, which in fact is the most common type of cancer.
This latest finding is thought, by health experts, to help encourage more people to protect themselves from skin cancer by debunking the idea that sunscreen leads to vitamin D deficiency.
Vitamin D deficiency is a global issue
Vitamin D deficiency is a very big problem globally and debates on how to tackle this while limiting the risk of skin cancer have been ongoing however three separate studies published by leading experts from London and Australia in the British Journal of Dermatologyhave concluded that the use of sunscreen does not impact on the vitamin D status in the majority of people.
Professor Antony Young, of Kings College London and lead author of the first study said:
"Sunlight is the main source of vitamin D. Sunscreens can prevent sunburn and skin cancer, but there has been a lot of uncertainty about the effects of sunscreens on Vitamin D."
"Our study, during a week of perfect weather in Tenerife, showed that sunscreens, even when used optimally to prevent sunburn, allowed excellent vitamin D synthesis."
