Controversies in Vitamin D Research: Clinical and Methodological Considerations
Vitamin D is the most talked about and written about nutrient of the past decade, with celebrities like Oprah, Gwyneth Paltrow, and Katy Perry discussing vitamin D deficiency in social media. The widespread attention to vitamin D has contributed to a 400 million dollar increase in vitamin D supplement sales in the past 10 years. But does vitamin D supplementation prevent adverse health outcomes? The objective of the proposed symposium is to discuss important controversies in vitamin D research that impede our understanding of this causal relationship. International experts on vitamin D will discuss methodological considerations and clinical implications of current vitamin D research, including (1) measurement of vitamin D status in epidemiologic studies; (2) whether more observational studies are needed to address maternal vitamin D and poor birth outcomes; (3) objectivity versus advocacy in vitamin D research; and (4) the impact of weak evidence on changing clinical practice.
