What Ergothioneine is
A diet-derived antioxidant amino acid that accumulates in cells via a dedicated transporter, studied as a possible longevity nutrient.
Ergothioneine is a naturally occurring sulfur-containing amino acid obtained from the diet, notably mushrooms, that the body actively concentrates in cells through a specific transporter. Its selective uptake and antioxidant properties have led researchers to propose it as a protective longevity nutrient, with lower blood levels linked to some age-related diseases.
Mechanism: Concentrates in tissues via the OCTN1 transporter and scavenges reactive oxygen species, protecting mitochondria and DNA.
Regulatory history: Sold as a supplement / food ingredient; not an approved drug
How TGA treats this kind of product
Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.
The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for Ergothioneine at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
