Introduction
Sodium bicarbonate is one of the most consistently supported ergogenic aids in sports nutrition research, yet its underlying mechanisms and real-world applications remain widely misunderstood.
For many athletes and coaches, the common story is that sodium bicarbonate works by lowering blood lactate. In fact, the opposite occurs: blood lactate is often elevated post-exercise when sodium bicarbonate has been ingested.
Recent meta-analyses indicate that sodium bicarbonate supplementation consistently provides a performance benefit in the range of 1–3%. On paper that may seem modest, but in competitive sport such differences often separate podium places from the rest of the field.
More recent developments have focused on how to optimise both the timing and formulation of supplementation. The “individualised ingestion timing” approach has emerged as a practical strategy, recognising that the time-to-peak blood bicarbonate concentration varies considerably between individuals.
Similarly, novel formulations are being explored to address issues with gastrointestinal distress and practicality of dosing. These include topical approaches such as sodium bicarbonate lotion, and commercial products like Maurten’s “Bicarb System.”
Looking forward, important questions remain. While classically linked with short-duration, high-intensity efforts, there is growing interest in whether bicarbonate supplementation could also benefit endurance exercise performance, either directly or via enhanced training quality.
In this episode, Prof. Lewis Gough joins to discuss the latest evidence on sodium bicarbonate and performance, its mechanisms, novel delivery systems, and the key directions for future research.
