Organization and Activities​

The Vitamin D Workshops bring together basic researchers, clinicians and nutrition experts from around the globe. Since the first meeting in 1973, there have been 20 Vitamin D Workshops with #21 to be held in May 2018.  We host a multi-day forum where the latest research on Vitamin D is presented, debated and shared​. 

​The Workshops are organized by a dedicated group of internationally recognized scientists who are experts on Vitamin D.  The Workshop Executive Committee (WEC) is responsible for planning and implementing the annual meetings. The Program Advisory Committee (PAC) assists the WEC in choosing session topics, speakers and awardees for each workshop. Members of both the WEC and the PAC contribute to editing and reviewing manuscripts for the Proceedings of each Workshop.

The Vitamin D Workshop is a 501c3 non-profit organization incorporated in 1974


We are dedicated to organizing annual Vitamin D Workshops, which are international scientific meetings that focus on the biology and health implications of Vitamin D​
