Does sunscreen block the vitamin D that naturally comes from the sun's rays?

No, while sunscreen blocks some of the vitamin D provided by the sun, the benefits of using sunscreen far outweigh the benefits of receiving vitamin D in this manner. According to the Cancer Council, regular use of sunscreen when the UV Index is 3 or above during normal daily activity should not stop you getting enough vitamin D.
