2. What Is Alpha Lipoic Acid?
Alpha Lipoic Acid (ALA), also known as thioctic acid, is a naturally occurring organosulfur compound synthesized in small amounts by plants, animals, and humans. Industrially, it is produced under controlled conditions to ensure high purity, stability, and suitability for commercial formulations.
Unlike many single-solubility compounds, ALA is both water- and fat-soluble, making it highly versatile for use in capsules, tablets, powders, beverages, creams, and emulsions.
Important Note:
AIHerba® Alpha Lipoic Acid is supplied strictly as a raw material ingredient and is not marketed as a drug or treatment.
