I also have been getting us all as a family to take more Vit D because we live on Vancouver Island in the Pacific North West which is mostly covered in cloud for the whole winter. I just saw the news this week re Vit D supplements so for now we have all have stopped them. To be honest I wonder if the hundreds if not thousands of GBP then CAD $ I have probably spent on supplements in my lifetime,I'm 69 yrs old this yr, have been a total waste of my hard earned money ?
