Biological Properties

Alpha lipoic acid (ALA) is one of the most potent biological antioxidants known. Referred to as the “universal” antioxidant, ALA is unique among anti-oxidants, demonstrating anti-oxidant activity in aqueous, as well as in lipophilic regions, and in extracellular and intracellular environments. Also unique among anti-oxidants, ALA participates in the recycling of other important endogenous anti-oxidants such as vitamins E and C, ubiquinone and glutathione.

The primary role of antioxidants is to act as scavengers of free radical molecules, inactivating various reactive oxygen species (hydroxyl radicals, nitric oxide radical, peroxynitrite, hydrogen peroxide, hypochlorite, singlet oxygen, and peroxyl radicals). Oxygen-derived free radicals can damage DNA, proteins and lipids, resulting in inflammation and acute and delayed cell death. The body protects itself from the harmful effects of free radicals and other oxidants through multiple anti-oxidant enzyme systems such as superoxide dismutases (SOD), peroxidases, and through natural antioxidant molecules such as glutathione. When too many free radicals are produced for the body’s normal defenses to convert, “oxidative stress” occurs with a cumulative result of reduced cellular function, and ultimately, disease.
