The sodium salt of citric acid, a common food-grade buffering and flavoring agent.
Why it’s used
Used in supplements as a pH buffer, flavor enhancer, or electrolyte source, and separately studied as an alkalizing agent taken before exercise.
What the evidence is for
pre-exercise alkalizing effect on high-intensity exercise performance.
What the evidence says
Some controlled studies have examined sodium citrate loading before high-intensity exercise, with mixed results on performance; effects are inconsistent across studies and often modest where present. As a plain excipient/flavoring use, it has no efficacy claim attached.
Dose studied
0.3–0.5 g — per kilogram body weight dosing used in some pre-exercise sodium citrate loading studies.
Context
Exercise-performance studies have generally used single doses in the range of several grams taken before exercise, with considerable variability in protocol and outcome between studies.
