I am officially vitamin D deficient, so trying to walk even more outside. However my personal pharmacist gave me some pharmacological advice and I have now been dosed up for 1 month, so my body can catch up quicker. Another two monthly doses and I will be able to take normal supplement. You need it in Australia. The problem we have is the sunscreen, long sleeves, hats and shaded areas protecting us from the sun. It is a vicious circle.
