What is Ergothioneine Powder?

Basic Definition:Ergothioneine (EGT) is a naturally occurring chiral amino acid antioxidant first isolated from the *Claviceps purpurea* fungus in 1909. Chemically known as 2-mercaptohistidine betaine, it has the molecular formula C₉H₁₅N₃O₂S and a CAS number of 497-30-3. Ergothioneine powder is the refined and dried form of this compound—a fine, white to off-white powder—designed to facilitate ease of storage, transportation, and application in downstream product manufacturing.

Core Characteristics: It possesses high natural safety; it occurs naturally within the human body, is non-toxic, and non-irritating. It can efficiently enter cells and mitochondria via the specific transporter protein OCTN1. It demonstrates extremely potent antioxidant capabilities: its capacity to scavenge hydroxyl radicals is 25% higher than that of Vitamin E and 3.5 times greater than that of glutathione. Furthermore, its biological half-life is significantly longer than that of polyphenols, endowing it with exceptional stability. It offers a multifaceted array of benefits—including antioxidant, anti-inflammatory, and skin-brightening effects—making it suitable for diverse applications across multiple fields.

Production and Specifications: Production predominantly utilizes biological fermentation methods—such as deep-tank fermentation using fungi—yielding a purity level exceeding 99.9%. This approach reduces production costs by over 90% compared to traditional chemical synthesis methods and adheres to green manufacturing standards. Common packaging specifications include 1 kg bags and 25 kg cardboard drums. The product has a shelf life of approximately two years and requires storage in a sealed container, in a cool environment, and away from light to prevent the loss of biological activity. Additionally, a plant-extract form (with a purity of 0.5%–1.0%) is available to meet the specific requirements of various product formulations.

Natural Sources: Ergothioneine is widely distributed in fungi, various types of mushrooms, animal tissues (such as erythrocytes and the liver), and certain plants. While mushrooms contain the highest concentrations of the compound, natural extraction methods yield low output at high costs; consequently, biological fermentation has now emerged as the dominant production method, enabling large-scale commercial supply.

Core Benefits of Ergothioneine Powder
