What does it really take to fuel like an Olympic athlete?
In this episode of From A to Zinc: The Supplement Podcast, host Charleen speaks with Professor Louise Burke, one of the world’s leading authorities in sports nutrition and the former head nutritionist for Olympic athletes, to uncover how science, strategy, and precision come together to achieve peak performance.

With over four decades of research and hands-on experience, Professor Burke explains how athletes at the highest level approach fueling, recovery, and supplementation, and how those same principles can help anyone improve performance, endurance, and overall health.

The conversation explores:

•How the science of sports nutrition has evolved from a “food-first” philosophy to a precision, data-driven approach
•Why third-party testing and supplement regulation are essential for safety and credibility
•What current research reveals about gender differences in performance and recovery

Professor Burke also shares why sports nutrition remains one of the most dynamic areas in health science - how new discoveries, from nitrates to caffeine efficacy, continue to reshape the field and inspire ongoing learning for both professionals and athletes.

Whether you’re an elite competitor, a dedicated gym-goer, or simply someone who wants to optimize your training and recovery, this episode offers a clear, evidence-based roadmap to fueling smarter, performing stronger, and recovering better.
