Ergothioneine is a little-known amino acid with powerful antioxidant and anti-inflammatory properties.
”Ergothioneine is sometimes called the ‘longevity vitamin’ (even though it is not technically a vitamin), since studies show that it reduces all-cause mortality and is associated with longer life span. For example, a 2020 study that followed thirty-two hundred health-conscious people for more than twenty years evaluated the association of 112 different metabolites in their blood with cardiovascular disease and all-cause mortality. The one that made the difference out of all 112 was Ergothioneine; the higher the blood levels of Ergothioneine, the lower the risk of cardiovascular disease and death.” – Dr. Sarah Ballantyne, Nutrivore, p.86
”Mushrooms are the dominant food source of Ergothioneine, which is particularly high in medicinal mushrooms and some culinary varieties like shiitake, maitake, and oyster. For example, oyster mushrooms contain double the Ergothioneine per kilogram of button mushrooms. Ergothioneine can be found in a few other foods, including tempeh, kidney beans, asparagus and chicken liver.” – Dr. Sarah Ballantyne, Nutrivore, p. 86
