A few months ago I wrote about Ryan McLaughlin who single handedly petitioned the Scottish Government to produce guidelines on vitamin D supplements for children and pregnant women, launch an awareness campaign and investigate the link between multiple sclerosis and the vitamin.
The result of his efforts have paid off handsomely and now an international conference is to be held in Scotland on 27 April to discuss the health effect of the vitamin. Leading researchers into links between vitamin D deficiency and MS are expected to attend.
Last week, as the Public Petitions Committee agreed to close Ryan's petition, members congratulated him for his achievement. I do too.
