Brief
Lipoic Acid (CAS No. 1077-28-7), also known as Alpha-Lipoic Acid (ALA) or Thioctic Acid, is a naturally occurring sulfur-containing compound that functions as a coenzyme in energy metabolism. It is often referred to as the “universal antioxidant” because it is both water- and fat-soluble, enabling it to work in nearly every part of the body. Lipoic acid is widely used in dietary supplements, cosmetics, and pharmaceuticals for its antioxidant, anti-aging, and metabolic support properties.
What is Lipoic Acid?
Lipoic acid is synthesized in small amounts by the body and is also found in foods such as spinach, broccoli, organ meats, and potatoes. It plays a critical role in mitochondrial energy metabolism, helping convert glucose into ATP (energy).
What makes lipoic acid unique is that it can:
- Regenerate other antioxidants like vitamin C, vitamin E, and glutathione
- Cross the blood-brain barrier, supporting neurological health
- Work in both aqueous (water-based) and lipid (fat-based) environments
