product introduction
L-ergothioneine (EGT) powder is a naturally occurring sulfur-containing derivative of the amino acid histidine. It was first identified in fungi more than a century ago. As a highly stable antioxidant, it is utilized in products within the fields of health supplements and cosmetics.
We employ two production processes—fermentation and chemical synthesis—yielding products with a purity exceeding 99%. Generally speaking, for products of equivalent content, the fermented version is slightly more expensive than the synthesized one; however, the fermented variant is better suited for "clean label" products and high-end skincare applications.
This product presents as a white powder and exhibits excellent water solubility, dissolving easily in water at room temperature. It is also soluble in organic solvents such as ethanol and methanol, facilitating its incorporation into various formulation systems—including gummies, liquid oral supplements, powdered beverages, and compressed tablets.
We can supply:
Golden Oyster Mushroom Extract (1% Ergothioneine)
99% Synthetic/Fermented Ergothioneine
50% Liposomal Ergothioneine
Third-party report
Our lab checks each batch of product to make sure it is really good and meets all requirements.
Before we ship we can also send some samples to another lab for testing.
You can choose a lab, like Eurofins, SGS, AIE or any other lab you prefer.
product strength
Regarding the bioavailability of Ergothioneine (EGT) in the human body, current scientific consensus and market data indicate that—contrary to earlier beliefs—it is not difficult to absorb. On the contrary, the human body possesses a specialized, "highly efficient transport system" specifically designed for it; however, this system can only be effectively utilized if the product overcomes the destructive effects of stomach acid and is manufactured using specific technical processes.
1. The Human Body Possesses an Exclusive "VIP Channel."
Many people mistakenly believe that Ergothioneine is difficult to absorb; this is, in fact, a misconception. The reality is that a specific transport protein known as OCTN1 exists on the membranes of human cells.
Specific Recognition: OCTN1 acts like a specialized "lock," allowing entry only to the "key" that is Ergothioneine.
Targeted Enrichment: Through this channel, Ergothioneine is rapidly absorbed into the bloodstream and preferentially delivered to tissues experiencing the most severe oxidative stress—and thus in greatest need of protection—such as mitochondria, the brain, the liver, the dermal layer of the skin, and red blood cells.
High Retention Rate: Studies indicate that once inside the body, Ergothioneine undergoes an extremely high rate of renal reabsorption. This means it remains within the body for a significant duration to exert its effects, rather than being rapidly excreted via urine.
2. A Dichotomy in Bioavailability: Standard vs. Premium
Although the human body possesses the necessary absorption channels, the specific form of the raw material determines how much of the active ingredient actually reaches these channels. The absorption rates of products in different forms vary dramatically:
Standard Raw Powder / Low-End Capsules | Low (<20%): Easily degraded by stomach acid; possesses a large molecular particle size, making it difficult to effectively interact with the OCTN1 transport proteins located in the intestinal tract; the majority is likely excreted via feces.
Enhanced Absorption Formulations | Moderate (45% – 65%): If supplemented with black pepper extract (e.g., BioPerine) or combined synergistically with other antioxidants (such as Vitamin C or Glutathione), absorption efficiency can be improved to a certain extent.
Liposomal / Targeted Delivery Technologies | High (≥80%): Utilizes liposomal encapsulation technologies—such as LipoShield™—to mimic the structure of cell membranes. This protects the active ingredient as it passes through the stomach, allowing it to be released directly into the small intestine and subsequently penetrate cell membranes. Testing of some top-tier products has demonstrated actual bioavailability levels reaching 82% or even higher.
3. The Three Key Factors Determining Absorption Rate
When selecting a product or evaluating its efficacy, you should focus on the following three dimensions, as they directly determine the level of bioavailability:
Purity:
High-purity (≥99.9%) ergothioneine contains fewer impurities, allowing it to bind more precisely to the OCTN1 transporter protein. Studies have shown that, at equivalent dosages, a product with 99.99% purity boosts plasma antioxidant markers by over 68% more than lower-purity products.
Delivery System:
This is the core factor that sets superior products apart. Technologies such as liposomal encapsulation or sustained-release microencapsulation can boost bioavailability by more than threefold, helping the active ingredients cross the blood-brain barrier to reach the brain and nerve cells directly.
Product application
1. Cosmetics and Personal Care Industry
Ergothioneine is used a lot in the cosmetics and personal care industry. This is where it was first used commercially. It is still used the most today. People in the skincare world think it is a great ingredient. It is often used in anti-aging products.
Ergothioneine is very good at protecting skin cells from damage. It protects skin cells from damage caused by the sun. Helps keep skin looking nice. It does this by stopping radicals protecting skin cells from UV damage and helping to make collagen. This means it can help reduce wrinkles, make skin look firmer, and make it look brighter.
Ergothioneine is in skincare products like serums, face creams, eye creams, face masks, and sunscreens. Big brands like Estée Lauder and Clinique have been using it in their products for some time.
2. Dietary Supplements and Health Foods Industry
More and more people are getting interested in taking care of their health and looking good. This is why ergothioneine is becoming very popular in the supplements and health foods industry.
Ergothioneine is good for you because it’s properties: it helps your cells have energy, make you look younger, and is good for your brain and your liver. Your body cannot make ergothioneine on its own so you need to take it as a supplement.
You can buy ergothioneine as capsules or tablets. It is also added to some foods and drinks. In the United States and the European Union it is considered safe to eat.
3. Food Industry
Ergothioneine is not just used to make food healthier, it is also used to help keep food fresh.
It is a good antioxidant that is used to stop food from going bad. For example, it is used to stop seafood like shrimp and crab from turning. It is also used to keep meat products tasting and looking good.
Ergothioneine is allowed to be added to foods like drinks, dairy products, cereal bars, and chocolate. It makes these foods healthier. It does not break down when it is heated.
4. Pharmaceutical and Biotechnology Industry
The pharmaceutical and biotechnology industry is an area where ergothioneine is being used. It has a lot of potential.
Ergothioneine is very good at protecting cells. This makes it useful for keeping organs healthy when they are being transplanted. It is better at this than ingredients because it does not break down easily.
Ergothioneine is also being used in eye surgery. It helps keep the tissues in the eye safe.
Scientists are also studying ergothioneine to see if it can be used to treat diseases like Alzheimers.
5. Animal Feed Industry
Some animal feed now contains ergothioneine. This is a new use for it.
The idea is to help animals stay healthy by giving them antioxidants. This should also make the meat, eggs, and dairy products from these animals better.
