In this episode, we sit down with Josh Rowe to explore the science behind the Maurten Bicarb System and why sodium bicarbonate has become one of the most talked-about topics in endurance performance. We discuss: - how bicarbonate buffering works- why acidity contributes to fatigue- the history of sodium bicarbonate in sports science- why traditional bicarbonate caused major GI distress- how hydrogel delivery systems aim to improve absorption and tolerability- what types of runners and workouts bicarbonate may benefit- threshold training, marathon racing, and high-intensity applications -published scientific studies surrounding hydrogel bicarbonate systems- the growing role of delivery science in endurance nutrition This conversation focuses on the physiology, performance science, and practical application behind bicarbonate supplementation—not hype, but the evolving intersection of sports science, engineering, and endurance performance.
