Alpha Lipoic Acid (ALA) is a unique antioxidant that works in both water-soluble and fat-soluble environments — something almost no other antioxidant can do. It supports glucose metabolism (helping shuttle fuel into muscle cells), regenerates other antioxidants (vitamins C, E, glutathione, CoQ10), and serves as a direct cofactor in mitochondrial energy production. Most pre workouts don't include it. PurePump does — 100mg of ALA per serving — because managing oxidative stress and supporting glucose utilization during training are performance factors, not afterthoughts.
