On Thursday April 7, the Wellcome Trust Conference Centre at 183 Euston Road, London, will host a major vitamin D event between 9:30am-5:00pm: The Vitamin D Experts’ Forum.
You can read more about the event and book a place (this is not a free event) at The Vitamin D Association’s website.
This conference appears to be primarily intended for care providers, but perhaps not exclusively so. Concessions may be available.
If you have the funds, the time and the inclination it would be well worth attending.
