Seminar on Vitamin D in Nutrition and Health

Hanoi, Vietnam


Vitamin D is an essential nutrient, well known for its role in skeletal health. While Southeast Asian nations are situated near the equator, recent studies in this region have shown that deficiency of this vitamin is highly prevalent across all age groups, particularly in children. At the same time, the growing body of research examining the broader role of vitamin D in health beyond skeletal health has been gaining interest among the health and nutrition community. Currently, there is scientific debate about the optimal requirement level for vitamin D, with some nations revising recommended intake. More research in this area, including on appropriate cut-offs for assessment of vitamin D status, is clearly required. More importantly, awareness of vitamin D deficiency, its health implications and corrective actions need to be raised and addressed in the Southeast Asian region.


This important one-day seminar aimed to:

  • Provide an update on the multiple potential health benefits of vitamin D
  • Update on status of vitamin D among populations in SE Asia and optimal levels
  • Provide an overview of current understanding of the physiological role of vitamin D in human nutrition across the life cycle
  • Examine the role and importance of sources of vitamin D – sunlight vs food vs fortification vs supplementation
  • Update on issues related to assessment of vitamin D status and discuss the development of recommended intakes for vitamin D
