Ergothioneine for Anti-Aging & Skin Health

Ergothioneine is a naturally occurring sulfur-containing histidine derivative, first isolated and identified in 1909 by the French pharmacist Charles Tanret from the *Claviceps purpurea* fungus (ergot). As a rare amino acid that the human body cannot synthesize on its own, ergothioneine must be obtained through dietary intake; its primary sources include mushrooms (particularly *Ganoderma lucidum* and *Cordyceps sinensis*), certain animal tissues, and grains. Its molecular formula is C₉H₁₅N₃O₂S, with a molecular weight of 229.299 and a CAS number of 497-30-3; it appears as a white crystalline powder with a melting point of 275–277°C.

A unique feature of ergothioneine is the presence of a highly specific organic cation transporter—OCTN1—within the human body. This transporter actively transports ergothioneine into cells and mitochondria, delivering it precisely to the sites requiring protection. Ergothioneine is found in high concentrations within organs, cells, and biological fluids that are particularly susceptible to high levels of oxidative stress and inflammation—such as the heart, liver, kidneys, erythrocytes, the lens of the eye, and seminal fluid. This targeted transport mechanism allows its intracellular concentration to reach millimolar levels—far exceeding that of other antioxidants—thereby laying the foundation for its remarkable biological activity.

Anti-Aging Mechanisms: A Paradigm Shift from "Passive Antioxidant Defense" to "Active Metabolic Regulation"

Traditional Antioxidant Mechanisms: The "Scavengers" of Free Radicals

Ergothioneine has long garnered significant attention for its exceptional antioxidant capabilities. Its unique thioimidazole ring structure endows it with potent free radical-scavenging abilities, enabling it to broadly neutralize reactive oxygen and nitrogen species—such as hydroxyl radicals, superoxide, and peroxynitrite—even at nanomolar concentrations. Studies indicate that its antioxidant potency is six times that of glutathione; its free radical-scavenging efficiency is 14 times that of glutathione; its overall antioxidant capacity reaches 30 times that of Coenzyme Q10; and its efficacy in protecting against UV-induced damage is an astounding 6,000 times that of Vitamin E.

Ergothioneine’s antioxidant advantage lies not merely in its potent efficacy, but also in its remarkable stability and regenerative capacity. Unlike many antioxidants that are "consumed" and depleted after a single use, ergothioneine can restore its activity through the body's endogenous reduction systems after neutralizing highly damaging free radicals, thereby functioning in a continuous, cyclical manner. This characteristic enables it to provide sustained and long-lasting antioxidant protection.

A Revolutionary Discovery: A Novel Mechanism as a "Metabolic Signaling Switch"

Two independent studies published in *Cell Metabolism* in 2025 have fundamentally revolutionized our understanding of ergothioneine’s mechanism of action, redefining it from a passive antioxidant into an active "metabolic signaling switch."

Research by the Leibniz Institute for Analytical Sciences (Germany): This study revealed that ergothioneine acts as an alternative substrate for cystathionine-γ-lyase (CSE), thereby promoting the generation of hydrogen sulfide (H₂S). This process, in turn, induces persulfidation modifications across more than 300 distinct protein targets. Among these targets, the activation of cytoplasmic glycerol-3-phosphate dehydrogenase (cGPDH) via persulfidation was identified as the key mechanism through which ergothioneine elevates intracellular NAD⁺ levels.

Research by Harvard Medical School: This study confirmed that ergothioneine can directly bind to and activate 3-mercaptopyruvate sulfurtransferase (MPST), thereby enhancing the efficiency of mitochondrial energy metabolism. In a 6-week mouse study, ergothioneine supplementation resulted in a significant increase of approximately 14% in running distance and a speed improvement of about 28%.

The CSE-H₂S-cGPDH-SSH-NAD⁺ Pathway: The Core Route for Anti-Aging

This newly discovered pathway constitutes the core mechanism underlying the anti-aging effects of ergothioneine:

Substrate Substitution: Ergothioneine acts as a novel substrate for CSE, exhibiting an affinity that is even superior to that of the canonical substrate, cystathionine.

H₂S Generation: Under the catalysis of CSE, ergothioneine yields the products histidine betaine and H₂S.

Protein Persulfidation: The generated H₂S induces sulfhydryl modifications—specifically persulfidation—in proteins such as cGPDH.

Enzyme Activity Activation: Cysteine-243 on cGPDH serves as a critical modification site; following persulfidation, its enzymatic activity increases approximately twofold.

Elevated NAD⁺ Levels: The activated cGPDH significantly boosts intracellular NAD⁺ levels via the glycerol-3-phosphate shuttle system.

Experimental Validation: Comprehensive Evidence Ranging from Nematodes to Mammals

Lifespan Extension Effects: In *C. elegans* models, treatment with a low concentration of ergothioneine (450 µM) significantly extended both the median and maximum lifespans of the nematodes. In studies involving aged rats, oral administration of ergothioneine (20 mg/kg) nearly doubled exercise endurance while simultaneously improving angiogenesis, muscle mass, and stem cell abundance.

Improvement in Health Markers: Ergothioneine treatment significantly enhanced the nematodes' resistance to oxidative stress (induced by H₂O₂), chemical stress (induced by arsenate), and heat stress. Furthermore, it reduced the accumulation of lipofuscin and lipid deposits within the bodies of aging nematodes.

Verification of Mechanistic Specificity: In *C. elegans* and mouse cells with genetic knockout of the *CSE* gene, all beneficial effects of ergothioneine—such as lifespan extension, stress resistance, and improved exercise performance—were completely abolished, thereby confirming the pivotal role of the CSE pathway.

Skin Health Benefits: A "Smart Protective Shield" for Multi-Dimensional Skin Defense

Antioxidant and Anti-Photoaging Effects: The First Line of Defense Against Environmental Damage

The core value of ergothioneine in skincare lies in its exceptional antioxidant and anti-photoaging capabilities. It provides physical protection by absorbing UV radiation in the 257nm wavelength range; by spectrally complementing chemical sunscreens, it adds an extra layer of defense to the skin. From a biological repair perspective, it inhibits the UV-induced expression of Matrix Metalloproteinase-1 (MMP-1)—thereby reducing collagen loss by up to 37%—and significantly lowers the expression of pro-inflammatory factors such as IL-6 and TNF-α, effectively blocking UV-induced DNA damage.

Studies have demonstrated that under exposure to 100 kJ/m² of UVA340 radiation, ergothioneine scavenged reactive oxygen species (ROS) both faster and more effectively than idebenone. In cells treated with ergothioneine, a reduction in ROS levels was observed immediately following irradiation, whereas the ROS-reducing effect of idebenone on fibroblasts did not become apparent until after a certain delay. One hour later, idebenone had reduced ROS levels in fibroblasts by 6.2%, while ergothioneine achieved a reduction of 17.5%.

Whitening and Brightening: A "Skin-Illuminating Engine" for Inhibiting Melanin Production

By inhibiting tyrosinase activity, ergothioneine hinders the formation and deposition of melanin, thereby improving skin tone and rendering the complexion fair, translucent, and radiant. Research results indicate that when ergothioneine is incorporated into cosmetic formulations at concentrations ranging from 0.01% to 0.03%, it effectively impedes the formation and deposition of melanin. Its skin-whitening mechanism extends beyond merely inhibiting tyrosinase; it also encompasses the reduction of UV-induced hyperpigmentation and the inhibition of protein glycation within the skin.

Barrier Repair and Anti-Inflammation: The "Stable Cornerstone" for Building Skin Health

Ergothioneine possesses the ability to penetrate skin cell membranes and exert its effects deep within the skin's foundational layers. It not only neutralizes free radicals but also regulates intracellular redox states and activates antioxidant enzymes, thereby strengthening the skin's barrier function and enhancing its resilience and self-repair capabilities. Its exceptional anti-inflammatory properties precisely soothe skin redness and sensitivity, creating a stable and healthy reparative environment for a fragile skin barrier.

Synergistic Enhancement: Building a "1+1 > 2" Skincare Matrix

Ergothioneine demonstrates excellent synergistic potential and is frequently paired with other active ingredients to deliver more comprehensive skincare results. For instance:

Paired with Astaxanthin: Establishes a more comprehensive antioxidant network.

Combined with Hyaluronic Acid: Strengthens the skin's moisture barrier while simultaneously addressing signs of aging.

Combined with β-Nicotinamide Mononucleotide (NMN): Forms a "Golden Anti-Aging Duo" that defends against external stressors while repairing from within; Ergothioneine clears free radical interference to facilitate NMN's cellular energy-boosting processes, while NMN provides ample energy support for Ergothioneine's sustained antioxidant defense.

 

Other Health Benefits: Comprehensive Protection Beyond the Skin

Neuroprotection and Cognitive Enhancement

Research conducted by Huazhong Agricultural University revealed that ergothioneine can ameliorate oxidative stress, neuroinflammation, and mitochondrial dysfunction induced by D-galactose-induced aging in a mouse model, thereby improving the mice's cognitive function. Following ergothioneine treatment, the compound was detected in the mice's liver, kidneys, heart, intestines, and brain, suggesting its potential to cross the blood-brain barrier. The study further demonstrated that ergothioneine treatment significantly mitigated memory impairment in the D-galactose-induced aging mouse model, effectively enhancing memory function.

Cardiovascular Health

Ergothioneine has been associated with reduced mortality rates and a lower risk of cardiovascular disease. Its accumulation in high concentrations within cardiac tissue provides a tissue-specific basis for its cardioprotective effects.

Enhanced Athletic Performance

Research from Harvard Medical School demonstrated that during a six-week experimental period involving mice, ergothioneine supplementation led to a significant increase—approximately 14%—in running distance and a speed improvement of roughly 28%, thereby revealing its direct performance-enhancing effects. This effect is closely linked to ergothioneine's activation of MPST and its ability to boost the efficiency of mitochondrial energy metabolism.

Ocular Health

Jin San Bio-Innovation launched the world's first ergothioneine-infused eye wash solution (containing 5,000 ppm of high-purity ergothioneine), which effectively addresses issues such as dry eyes and eye fatigue; within just six hours of its market debut, sales revenue surpassed 2 million RMB. The accumulation of ergothioneine in high concentrations within the ocular lens provides the physiological basis for its protective effects on the eyes.
