Potassium aspartate-citrate is sometimes used as a supplement to support athletic performance and exercise recovery due to its potential roles in electrolyte balance and reduction of muscle fatigue. Potassium is a crucial electrolyte involved in nerve function, muscle contraction, and fluid balance, which are all important during physical activity. Aspartate and citrate are intermediates in metabolic pathways and are thought to potentially help mitigate fatigue by participating in the Krebs cycle and reducing the accumulation of acidic metabolites in muscles.

Some early studies, primarily from the 1970s and 1980s, suggested that potassium aspartate supplementation could help reduce feelings of fatigue and improve endurance in athletes, possibly by enhancing aerobic metabolism and buffering lactic acid. However, these studies were small, and their methodologies have since been questioned. More recent and rigorous clinical trials are lacking, and systematic reviews generally conclude that the evidence supporting potassium aspartate-citrate for improving athletic performance is weak or inconclusive. The use of potassium citrate, specifically, has been better validated for kidney stone prevention rather than athletic enhancement.

Overall, while the theoretical basis for the use of potassium aspartate-citrate in exercise settings exists and there is some limited, dated scientific literature, robust, high-quality evidence is lacking. As such, its use as an athletic or exercise aid is only modestly supported by science, with a low overall level of evidence.
