Blood alkalosis induction and exercise performance during high-intensity exercise
Trained athletes performing high-intensity and supramaximal exerciseNarrative review of RCTs and physiological studies
Low

Sodium citrate at 500 mg/kg body mass in capsule form reliably induces blood alkalosis and is most beneficial for short-duration, very high-intensity exercise; only 25% of observations showed significant performance improvements in high-intensity intermittent exercise, and gastrointestinal symptoms are a key limiting factor.

Dose:
Capsule administration preferred over liquid to reduce GI distress.
Performance during supramaximal cycling (time to exhaustion)
Trained male cyclistsRandomized crossover trial
Low

Sodium citrate ingestion significantly increased time to exhaustion during supramaximal cycling exercise versus placebo, associated with reduced intramuscular acidosis and improved metabolic performance.

Dose:
Individual RCT; small sample size; effect may not generalize to all exercise modalities.
