Dear Colleagues,

On behalf of the organizing committee it is our great pleasure and a special privilege to invite you to participate in the 3rd International Conference "Vitamin D - minimum, maximum, optimum" which will be held in Warsaw in September 22 - 23, 2017, under the auspices of the European Vitamin D Association (EVIDAS).

The conference serves as an international forum for the presentation and discussion of current basic and clinical research in the field of vitamin D. Organizing the subsequent edition of such a conference on vitamin D, given that the vitamin is widely advertised as a solution for a large spectrum of diseases and health issues, seems to be a challenge. Growing number of pharmaceuticals and supplements containing vitamin D, increasing availability of them in pharmacies, stores, online distribution and, sometimes, an intrusive commercial publicity campaigns have raised great interest, and have triggered reasonable controversies and fears. The self-administration of high doses of vitamin D has also appeared major concern in society. There is an increasing number of dilemmas regarding side effects including nephrocalcinosis, urinary stone disease, drug interactions and other adversity. On the other hand, it is recognized that vitamin D deficiency is a global health problem with potential negative consequences on health, welfare and morbidity during growth and adulthood, and therefore influencing health care services worldwide. According to current published reports, the vitamin D deficiency is regarded a significant risk factor for several civilization diseases including cancer, cardiovascular diseases, hypertension, autoimmune and metabolic disorders, infectious diseases and many other chronic conditions. Thus, it is essential to discuss vividly, and share scientific reports and evidence demonstrating both the safety issues and the significance of vitamin D for health of children, adolescents, middle-aged men and women, professionally active individuals, and seniors.

We believe that the scientific program of the 3 rd Conference "Vitamin D - minimum, maximum, optimum" with the confirmed attendance of leading experts in the area and outstanding speakers from many European countries, Israel, Canada and the United States will guarantee a high quality of this meeting. The diversity and multidisciplinary nature of the conference offers a unique opportunity to interact with specialists from different fields of science, share innovative opinions, address intriguing questions resolving major issues, and to discuss your scientific developments and research experiences. We look forward to welcoming you in Warsaw for the 3 rd International Conference "Vitamin D - minimum, maximum, optimum", September 22 - 23, 2017.
