Ah Vitamin D. You've become quite a celebrity recently. You seem to be in every health story I read. The majority of the Vitamin D created in our bodies come from exposure to sunlight and after years of slapping on the factor 50 and worrying about skin cancer, it would appear we have all become D deficient.
When the Chief Medical Officer in England, Dame Sally Davies, announced last week that she is worried that young children and some adults are not getting enough vitamin D, she gave official recognition to growing concern among health professionals that deficiency of this vitamin is a very significant issue in the UK.
