What GlyNAC is
A combination of glycine and NAC studied in older adults for restoring glutathione and improving multiple markers of aging.
GlyNAC is the combination of the amino acid glycine and N-acetylcysteine, the two building blocks the body needs to make glutathione. Trials from a Baylor research group in older adults reported that GlyNAC restored glutathione, reduced oxidative stress and inflammation, and improved several aging-related measures including strength and cognition.
Mechanism: Supplies glycine and cysteine to rebuild depleted glutathione, lowering oxidative stress and supporting mitochondrial function.
Regulatory history: Supplement combination; 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 GlyNAC 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.
