Vitamin D in sport: Hype, evidence, and practical guidance

Vitamin D has become one of the most talked-about nutrients in sport. Yet, confusion and controversy remain. Join two world-leading experts as they unpack the latest science, clarify the evidence, and translate it into clear, practical strategies for your athletes. You’ll learn what the evidence really says, how to assess vitamin D status without falling into common traps, and how to manage it safely in practice.

In part 1, Prof Graeme Close explore the latest research on vitamin D's role in muscle function, immunity, bone health, and performance, separating solid evidence from hype.

In part 2, Dr Dan Owens discuses everything from blood tests to biomarkers. Assessing vitamin D status sounds straightforward - but it’s not. This talk highlights the practical challenges, interpretation pitfalls, and common errors professionals make when monitoring vitamin D, and how to avoid them.

In part 3, both Graeme and Dan explore when and how to test, what levels to aim for, and how to supplement safely and effectively across seasons. Clear, evidence-based guidance for practitioners who want to move from theory to impact.

If you give advice on vitamin D, this is a must watch.
