Guest guest Posted August 15, 2008 Report Share Posted August 15, 2008 Hi any and all. I want to revisit my quest to find out what other vitamins the sun imparts besides D and when does it do it? How did they find out the sun gave vitamin D? Is there a lab test that could be used to analyze what the rays at different times of the day? How much are we hurting ourselves by not being outdoors at all times? ep Quote Link to comment Share on other sites More sharing options...
