Alpha Lipoic Acid (ALA, CAS 1077-28-7) is a naturally occurring organosulfur compound present in small amounts in foods such as spinach, broccoli, and organ meats. It is also produced in the body as part of normal cellular metabolism. Due to its unique dual solubility in both water and lipid systems, ALA is highly valued as a versatile functional ingredient in modern nutrition and wellness formulations.
Natural Field supplies high-purity alpha lipoic acid bulk powder with excellent stability, controlled particle size, and broad formulation compatibility, making it suitable for capsules, tablets, powders, functional beverages, and advanced nutritional blends. We also support wholesale alpha lipoic acid powder for OEM/ODM projects, and provide complete technical documentation, including COA and MSDS, for global customers.

Alpha lipoic acid increases glutathione levels, providing better protection against UV-induced pigmentation than glutathione itself, thereby protecting the skin from UV damage. This natural antioxidant is produced in the body and can also be taken as a supplement.
In clinical trials, alpha-lipoic acid supplement significantly reduces dark spots. Alpha lipoic powder has a significant inhibitory effect on tyrosinase activity, which increases with the concentration of water-soluble alpha-lipoic acid.
Research and formulation studies suggest that alpha lipoic acid can interact with key enzymes involved in melanin formation, support antioxidant enzyme activity, and help moderate processes associated with uneven pigmentation appearance. It is often incorporated into serums, creams, lotions, and brightening-oriented cosmetic products as part of a balanced antioxidant system. Its compatibility with other cosmetic actives makes it a versatile ingredient for modern skincare development.
