Trisodium citrate
What the trials found
Trisodium citrate does not have enough evidence to promise better exercise performance or less fatigue in athletes during short, intense efforts.

Dose, timing & forms
How much
There is not enough reviewed consumer evidence to set a dependable dose range for trisodium citrate. Research on sodium citrate has tested body-weight-based pre-exercise protocols, but results vary across exercise formats and the limited evidence here does not justify treating any protocol as proven. 1 If you choose to use it, follow a product label and discuss body-weight-based dosing with a qualified sports dietitian or clinician.
When and how long
This is a pre-exercise ingredient, not an occasional energy boost during a workout or a daily fatigue supplement. Studies of sodium citrate generally use it before hard exercise so blood buffering changes occur before the session starts. 1 Because the evidence reviewed here is limited, do not assume a specific timing schedule reliably improves performance.
Forms & standardisation
Look for a label that clearly identifies trisodium citrate or sodium citrate and states the amount per serving. Do not assume that citric acid provides the same effect: citrate buffering research evaluates sodium citrate, which also changes sodium intake. 1 Evidence does not establish one branded extract, citrate ratio, or capsule format as superior.
What this is and how it works
- The cited meta-analysis reports exercise-performance effects, but the supplied record provides no pooled effect size or MCID comparison 1.
- One paper reviewed here spans two consumer-facing outcomes involving exercise performance and fatigue.
Trisodium citrate is the sodium form of citric acid, a naturally occurring compound found in citrus fruits. In supplements, it delivers citrate alongside sodium and is usually taken before demanding exercise rather than as a daily wellness ingredient. 1
During all-out exercise, muscles produce hydrogen ions that make the internal environment more acidic. Trisodium citrate gets processed into bicarbonate, which works like a chemical sponge that soaks up some of that acid outside the muscle cells. 1 This buffering idea is biologically plausible, but the reviewed consumer evidence contains only one paper, so it does not establish a reliable performance effect.
Bottom line
Trisodium citrate is worth considering only for experienced athletes curious about buffering strategies for short, punishing efforts. The reviewed evidence is too limited to promise better performance or less fatigue, and it is not a strong pick for everyday energy. People managing sodium intake or using medicines should check with a clinician before experimenting.
