Creatine is one of the most researched supplements in sport, with decades of evidence showing clear benefits for strength and power athletes. But what about endurance sport, and cycling in particular? Creatine is back in the spotlight, hyped as everything from a sprint enhancer to a brain-boosting miracle.

In this episode, Ronan Mc Laughlin sits down with sports dietitian and researcher Dr Alan McCubbin to cut through the noise. They explore what creatine actually does in the body, the science behind traditional and high-dose protocols, why the original studies on endurance performance might be wrong and what recent studies really show for cyclists. They also look beyond performance, asking whether creatine has a role in brain health, ageing, or recovery.

If you’ve ever wondered whether creatine belongs in your supplement routine or if it’s just another short-cut-promising fad, this conversation has the answers.
