Sodium Bicarbonate for Performance: Benefits, Dosing and Side Effects | Prof. Lewis Gough
In this episode of We Do Science, I’m joined by Professor Lewis Gough to explore sodium bicarbonate supplementation and its role in sport and exercise performance. We discuss how it works, what the research tells us, and what matters when translating that evidence into practice.
Lewis explains the science of buffering, clears up common misconceptions about lactate and muscle fatigue, and shares insights from his research with athletes. We explore which types of exercise may benefit, why individual responses vary, and why a study’s average result doesn’t tell the whole story.
We also discuss the practical considerations: dose, timing, gastrointestinal side effects, and the differences between powders, capsules and newer delivery systems. Lewis shares his perspective on combining sodium bicarbonate with other supplements, including beta-alanine, caffeine and nitrates, highlighting where the evidence is stronger and where questions remain.
Whether you’re a sports nutrition practitioner, coach or athlete, this conversation explores how to assess sodium bicarbonate’s place within a performance nutrition strategy—and why the individual athlete and their sporting demands matter.
