GeneIII, the leading brand in premium L-Ergothioneine
At GENEIII, science comes before everything else. We’re driven by biotechnology, guided by pharmaceutical-grade precision, and committed to full transparency in everything we do.
Not All L-Ergothioneine Is Created Equal
At GENEIII, we go beyond the label. Our L-Ergothioneine is defined by four pillars that set us apart:
Most brands don’t make their own ingredients. Many buy bulk powder from unknown factories, or use mushroom extracts. Mushroom extracts may sound natural, but they’re inconsistent, impure, and often contain only trace amounts of ergothioneine. Our biotechnology process guarantees consistent potency, purity, and bioavailability in every capsule. At GENEIII, we do things differently. We’re scientists, not resellers. Every step— from fermentation to purification to encapsulation— happens in-house using our patented bioengineering process to produce 99.99% pure L-Ergothioneine. That means full control, full traceability, and zero compromises.
Every decimal matters. Our patented fermentation process yields L-Ergothioneine so pure, it sets the benchmark for the entire industry. This means you are fueling your body with the purest form of the "Longevity Vitamin," free from contaminants and fillers.
With over 30 international patents, GENEIII is actively shaping the future of ergothioneine science. This is the foundation that guarantees you receive real biotechnology—not just another supplement.
While competitors reference public studies, we actively advance the science. GENEIII sponsors Investigator-Initiated Trials (IITs)—rigorous, independent clinical studies designed to validate the efficacy of our specific ingredient. Our commitment to this level of proof ensures that every capsule you take is backed by direct evidence of its safety and efficacy, not just recycled promises.
