Alpha lipoic acid (ALA) is a naturally occurring compound with antioxidant properties that is sometimes promoted as a supplement to support athletic performance and exercise recovery. The rationale behind its use in this context centers on its ability to neutralize free radicals generated during intense physical activity, potentially reducing oxidative stress and muscle damage. Some studies have suggested that ALA supplementation may help decrease markers of oxidative stress and inflammation in athletes following strenuous exercise, and there is evidence that combining ALA with other antioxidants (such as vitamin C and E) could reduce exercise-induced muscle damage and improve recovery times. Additionally, ALA has been studied for its effects on glucose metabolism, which could theoretically support energy utilization during exercise. However, the clinical evidence supporting significant performance enhancement or improved recovery in athletes is limited and inconsistent. Most studies are small, short-term, and often use ALA in combination with other supplements, making it hard to isolate its effects. Systematic reviews generally conclude that while ALA may have some antioxidative benefits, the direct impact on athletic performance or exercise outcomes is not well established. Therefore, while there is a scientific rationale for its use, the evidence base is moderate to weak, and more rigorous research is needed to confirm its benefits for athletic and exercise support.
