Sodium Bicarbonate: 100 years of research, recent boom?

May 10, 2026 · 55 min · Ep 10

This week on Sunday Dinner we talk about sodium bicarbonate. It seems like everyone's trying it, and at many different disciplines from the 400 to the marathon. But what is it best for? How do you use it? Why should you use it? We explore how it works, what the research suggests are the best use cases and my own personal experiences. Despite its recent popularity there is almost 100 years of science exploring this supplement and more ways to use it rather than just a pre-packaged, pre-dosed system. I learned something new and I hope you do too, enjoy!
