Creatine and the Evolution of Performance Nutrition

Creatine is now one of the most widely used and well-researched supplements in elite sport — but few people know the story of how it first made its way into Olympic performance programmes.

In this episode of the Science for Sport Podcast, Richard Graves sits down with Steven Jennings, one of the key figures behind the early adoption of creatine in elite sport, to unpack a remarkable story that begins long before creatine was common knowledge.

Steven takes us back to the early 1990s — a pre-internet era where sports nutrition research travelled slowly, secrecy mattered, and a single kilogram of creatine played a role in reshaping performance preparation ahead of the Barcelona 1992 Olympic Games. From working directly with pioneering researchers at the Karolinska Institute to navigating Olympic-level scrutiny, this is a rare, first-hand account of how science moved from the lab to the field.

Beyond performance sport, the conversation also looks forward. Steven shares why he believes we are only just beginning to understand creatine’s wider potential — from cognition and ageing to plant-based diets and long-term health.

This is an essential listen for practitioners who want to understand not just what works in performance nutrition, but how evidence, trust, regulation, and timing shape real-world impact.

In this episode you will learn

• What creatine actually is and how it works at a cellular level
• How early research in the early 1990s changed elite sport preparation
• Steven’s role in bringing creatine into Olympic sport ahead of Barcelona 1992
• Why creatine was (and still is) legal, safe, and fundamentally different from banned substances
• How creatine became associated with repeated high-intensity performance and recovery
• Why creatine research is now expanding beyond sport into cognition, ageing, and health
• Why we may still be “scratching the surface” of creatine’s full potential

About Steven Jennings
Steven Jennings is a sports nutrition entrepreneur and former professional cyclist who played a pivotal role in the early commercialisation of creatine for elite sport. In the early 1990s, he worked directly with leading researchers from the Karolinska Institute to help translate groundbreaking creatine research into real-world Olympic performance programmes.

Over the past three decades, Steven has remained closely connected to the evolution of creatine research, from elite performance applications to emerging work in health, cognition, and ageing. Today, he continues to focus on education, innovation, and the future direction of creatine science.
