The Vitamin D Workshops are international scientific conferences that bring together basic researchers, clinicians and nutrition experts from around the globe. Since the first congress in 1973, there have been 21 Vitamin D Workshops with #22 in planning for May 2019.  We host a multi-day forum where the latest research on Vitamin D is presented, debated and shared​.  The Vitamin D Workshops are open to anyone with an interest in the biology and health implications of Vitamin D. An important outcome of our meeting is publication of a dedicated issue of the Journal of Steroid Biochemistry and Molecular Biology featuring work presented at the conference.  Proceedings from past meetings can be accessed under the Annual Conferences tab.  

​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.

As an non-profit organization, we rely on corporate sponsorships, exhibitors and government grants to fund the workshops.  Please contact us if you are interested in partnering with us in support of the 2019 congress.
