Dr.Ergo® L-Ergothioneine Bulk Powder
−−−Backed by US FDA-recognized GRAS status and supported by two human clinical trials for healthy longevity
Dr.Ergo® L-Ergothioneine is another premium ingredient we offer for supporting healthy longevity. It is produced in a facility certified by NSF cGMP and HACCP, utilizing licensed full enzymatic natural fermentation technology developed by the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences.
Dr.Ergo® L-Ergothioneine has been granted US FDA GRAS status—only the second ingredient of its kind—and is also authorized as a Novel Food in the EU. Its safety and efficacy have been confirmed through two human clinical trials.
Professor Barry Halliwell, a leading expert on antioxidants and healthy longevity, stated at 2025 Vancouver Ergothioneine Forum that intake of L-Ergothioneine is low among Americans and many other Western populations, which may contribute to poorer healthspan and lifespan. Our Dr.Ergo® L-Ergothioneine is well-positioned to help address this deficiency.
