Sequence, molecular data, research status and testing standards for Glutathione, written for Canadian researchers.
Glutathione is a naturally occurring tripeptide made of three amino acids: glutamate, cysteine and glycine. It is found in nearly every cell in the body and is one of the main molecules involved in managing oxidative stress.
Glutathione is one of the most studied molecules in cell biology. Researchers study how its reduced (GSH) and oxidized (GSSG) forms balance oxidative stress inside cells, and its role in detoxification pathways and in the function of mitochondria. Many studies look at how glutathione levels change with age and in different tissues.
What it is: A tiny natural chain the body makes, mostly in the liver.
The plain-English story: Your body is a bustling city, and glutathione is its street-sweeper, mopping up the damage left by everyday wear. The body makes it, so it is real and important. But injections and pills sold as 'glow' or 'detox' shots have thin evidence, and the skin-lightening claims in particular lack support.
What it does in the body: It is one of the body's main protectors against everyday cell damage.
What researchers are looking at: Heavily studied in labs. It is sold as a supplement and injection, but the evidence for benefits is mixed.
What you may hear online: Videos often call it a skin-whitening or detox shot.
The straight story: The body makes it naturally, but the evidence for shots is weak, and skin-lightening claims are not supported by good evidence.
The catch (where it stands in Canada): Depends on the product. If it is meant for people, look for an official number on the label.

How glutathione may be sold in Canada depends on the product, its form and the claims made for it. Products for human use must be authorized by Health Canada, either as natural health products or as drugs. Products sold online without authorization, or with health claims, may be illegal.

Products for human use should carry a Health Canada authorization number (an NPN or DIN) on the label. Be cautious of unauthorized products sold online whose contents cannot be verified. Speak with a licensed healthcare professional about any supplement.
Yes. Glutathione is a tripeptide, a chain of just three amino acids, which makes it one of the smallest biologically active peptides. It is unusual because one of its bonds uses the side chain of glutamate.
