This week on the podcast, Mikki speaks to omega-3 expert Greg Peoples to unpack the science behind these essential fats and their impact on health and performance. They discuss the differences between DHA, EPA, and pro-resolving mediators (SPMs), the best dietary sources—including the surprising mention of tuna—and what an optimal Omega-3 Index looks like. Greg also explains whether we can reach ideal levels through diet alone, or if supplementation is necessary.

They dive into omega-3s for athletes, covering their role in endurance performance, recovery, and even potential protection against atrial fibrillation in older endurance athletes. Greg breaks down their effects on muscle soreness, strength, and neuroprotection in contact sports, as well as the emerging link between omega-3s and sleep quality. Finally, they tackle supplement quality—how to choose a trustworthy brand in the wake of past industry scandals. A must-listen for anyone looking to optimise their omega-3 intake!

Associate Professor Gregory Peoples is a distinguished cardiorespiratory physiologist with over two decades of experience in researching and communicating the physiological roles of omega-3 fatty acids, particularly EPA and DHA, in optimising heart, muscle, and brain performance and recovery.

Based at the University of Wollongong, A/Prof Peoples has contributed significantly to understanding how dietary long-chain omega-3 polyunsaturated fatty acids, especially DHA, influence skeletal muscle physiology and function. He leads Ω3 Performance Physiology, a company dedicated to exploring the benefits of omega-3s in athletic performance and recovery.

Throughout his career, A/Prof Peoples has authored numerous high-impact papers on omega-3s, 

and his research has been instrumental in translating bench-top science into practical applications for both the general population and specialised groups, including elite athletes and military personnel. His work continues to influence dietary recommendations and therapeutic interventions aimed at enhancing physiological function and overall health.
