Summary
Sunscreen prevents sunburn and skin cancer, and current guidelines are that it should be routinely used when the maximum UV index is forecast to reach at least 3. However, applying sunscreen in laboratory experiments reduces vitamin D production, and there is concern that regular application of high SPF sunscreens might increase the risk of vitamin D deficiency. We propose a randomised controlled trial to determine if adhering to the current guidelines decreases vitamin D.
