People say they don't use sunscreen because they need the vitamin D. In order to get an adequate amount of vitamin D, you only need 10 minutes of sun [exposure]. I think it is safer to take a supplement or to get vitamin D from your diet. If you think your level is low, ask your doctor to check your levels. The sun is not the only way to get it.
