New sunscreen allows vitamin-D production

It has come to light that most sunscreens on the market block our ability to produce vitamin D, due to their effectiveness at blocking UV rays. A new sunscreen for sale in Australia may allow us to produce vitamin D and take advantage of being out in the sun without losing the UV-blocking capacities of the sunscreen.

Solar D is still under development, but is set to start the revolution of correcting our problematic sunscreen-related vitamin D deficiencies. We in Melbourne are often particularly low in vitamin D due to fewer usable sunshine hours without being slathered in sunscreen, so this will come as welcome news to the medical community, who have major concerns regarding our low levels of vitamin D.

Vitamin D is essential for bone strength and plays a role in our immune system. Vitamin D is required to absorb calcium and phosphate – essential elements of healthy bones and teeth. Vitamin D isn’t found in very high quantities anywhere else, including foods, with the highest sources being fish-liver oil, fatty fish, mushrooms, egg yolks and liver. We wouldn’t normally eat enough of these foods to get our required vitamin D, which means we need the sun or supplementation. UV rays are known to cause cancer, which should be avoided, however low vitamin D comes with its own set of problems.

Vitamin D is synthesised in the skin when we are exposed to UV-B rays. It depends where you live as to how much sunshine you need to get the recommended dose of between 600iu and 1,000iu of vitamin D each day.

The new product, Solar D, offers the same protection as SPF 30 sunscreens, but allows up to 50 per cent more vitamin D production.
