GENEIII | Health Supplement

Who is GeneIII? A biotech company first, a supplement brand second.

We make one molecule — L-Ergothioneine (EGT) — with our own production strain and a patented fermentation process, purified to 99.99%. We don't buy it. We grow it, encapsulate it in the USA, and send every batch to an independent lab before it goes anywhere.

Then we study it: GeneIII® EGT is evaluated in registered human clinical trials (WHO ICTRP). 30+ international patents. $15M+ invested in research. 180,000+ customers.

Science first.
