L Ergothioneine Powder is a crystalline form of the rare sulfur-containing amino acid derivative that is naturally made by advanced microbial fermentation technology. It is 99% pure. The product we make at Xi'an DN Biology Co., Ltd. stands out because it can effectively protect mitochondria and target cells intelligently using the OCTN1 transporter.
With over 13 years of experience working with plant extracts and the ability to process 3,000 tons of them every year, we offer pharmaceutical-grade quality that is backed by ISO 9001, GMP, HACCP, Kosher, and Halal certifications. Our factory has 4 × 6m³ extraction tanks and incorporated attention structures that make certain that each batch is the identical and that orders are crammed speedy—stock orders are shipped within 5–eight operating days.
Unlike most antioxidants, which break down quickly in sunlight, this one stays very stable at high temperatures and keeps growing back in your formulations. This makes it perfect for anti-aging products, neuroprotective supplements, and UV defence.

Protection at the Mitochondrial Level
Over time, oxidative stress builds up in your cells. Our L Ergothioneine Powder gets deep into mitochondria, which are the powerhouses of cells, and neutralizes free radicals where they start. Targeted action keeps cells making energy and saves the integrity of DNA.
Intelligent Bioavailability
Vitamin C and other traditional antioxidants have a hard time getting to tissues that need them. The OCTN1 transporter system in our product takes care of this by constantly delivering ergothioneine to areas that are under a lot of stress, like the liver, eyes, and skin. You get the most benefit with the least amount of medicine.
Long-Lasting Stability
Formulation problems are now over. Ergothioneine stays active even when it's exposed to UV light or heat, unlike other antioxidants that lose their effectiveness over time. Your goods keep working well for a long time, which cuts down on the need for re-formulation and customer complaints.
Complete System of Antioxidants
It is not sufficient on its very own. Ergothioneine works with other antioxidants to make a renewal cycle that protects for longer. Whilst combined with glutathione or vitamin E, the anti-growing old results are amplified with out raising the price of the substances.
Your customers demand visible results. Ergothioneine delivers:

Safe for broad consumer demographics:
These levels, which have been proven by science, make sure that all global markets follow the rules and provide real health benefits.
Step 1: A Microbial Cell Factory That Works
We've tweaked our own fermentation strains to get the most ergothioneine out of them. Our precise biosynthesis gets rid of the impurities that come from extracting plants.
Step 2: More advanced technology for fermentation
Four 6m³ fermentation tanks work under strict GMP rules. Real-time tracking makes sure that the purity of the L-isomer is the same in every batch.
Step 3: Purification with High Efficiency
The ultra-white crystalline powder you need is made by methods that combine stratification, decolorization, and spray drying. Before packaging, a final HPLC test confirms that there is 99% or more active content.
Proven Excellence in Manufacturing
We follow the strictest international rules because our buildings are ISO 22000, FSSC 22000, and FDA-compliant. Every measure is checked by our independent lab using HPLC, GC, and UV-Vis technology.

Flexible Partnership Options
If you need bulk raw materials or formulations that are made just for you, our OEM/ODM services can meet your needs. We keep up to 100 tons of stock ready to ship right away.

Rapid Response & Delivery
Orders that are in stock are shipped within 7 days of confirmation of payment. Our tech help team is available 24 hours a day, seven days a week. DDP shipping choices make international shipping easier.

Full Traceability
Our supply chain, that is linked to the blockchain, keeps song of every step, from planting base to completed powder. You get all of the paperwork you need, like certificates of analysis, allergen statements, and proof of wherein the meals came from.

Q: What good things does EGT do for your beauty?
A: As stated in answer A, ergothioneine protects cells from UV-induced photoaging. It improves fine lines around the eyes by protecting collagen structures and stopping inflammatory factors (like IL-6 and TNF-α) that cause skin to age faster than it should. In clinical studies, the skin's elasticity got better within 8 weeks of applying the product topically.
Q: How much ergothioneine should I put in my drinks?
A: You should use 0.025 g/kg for non-alcoholic and dairy-based drinks. You can have up to 0.040 g/kg of fresh dairy products. Grain-based bars can handle 0.2 g/kg, and chocolate goods can handle 0.25 g/kg without changing the texture or taste.
Q: What is better about the way you make things?
A: Our three-step process—engineered microbial synthesis, controlled fermentation, and precision purification—ensures pharmaceutical-grade uniformity. This is different from mushroom extraction, which results in varying levels of purity. Before being shipped, each batch is tested by a third party.
Q: Can ergothioneine be used instead of other vitamins in my formula?
A: Ergothioneine is strong on its own, but it works best when combined with other substances. It can be combined with Vitamin C to make your skin brighter or with CoQ10 to help your mitochondria. This mix lowers the total amount of antioxidants while increasing their effectiveness.
