Glutathione is your cells’ main defence against oxidative damage — it neutralises reactive molecules and helps the liver process toxins. Your body makes it constantly, and levels fall under oxidative stress, illness, and age. Swallowing it does not work well, because the gut breaks it down before it reaches circulation, which is why injectable and IV routes exist.
What people use it for. Antioxidant support, and liver and detoxification support.
What to know before you buy. The biology here is unusually well characterised for this range. Glutathione is the principal antioxidant inside your cells, it drives phase II liver detoxification, and it regenerates vitamins C and E after they have done their work. IV glutathione has established clinical use, notably alongside cisplatin chemotherapy. Separately, FDA has warned about injectable glutathione marketed for skin lightening — a different use from the ones above, and one this sheet does not cover.
What It's Studied For
| Research area | What that rests on |
|---|---|
| Antioxidant defence | The principal antioxidant your cells make; also regenerates vitamins C and E |
| Liver and detoxification | Central to phase II hepatic detoxification |
| Clinical precedent | IV glutathione has established use in specific protocols, including alongside cisplatin chemotherapy |
| Regulatory note | FDA has warned about injectable glutathione marketed for skin lightening — a separate use from the rows above |

At a Glance
- Class
- Endogenous tripeptide antioxidant (glutamate-cysteine-glycine)
- Function
- Principal intracellular antioxidant; central to phase II liver detoxification and regeneration of vitamins C and E
- Established use
- Intravenous glutathione has genuine clinical application, including in cisplatin chemotherapy protocols
- FDA position
- FDA has issued warnings regarding injectable glutathione marketed for skin lightening, citing safety concerns and unapproved status
- Oral limitation
- Oral glutathione is poorly bioavailable — largely broken down in the gut, which is the main argument for parenteral routes
- Regulatory (US)
- Not FDA-approved for skin lightening or general wellness use. Not on the July 2026 PCAC agenda
- Format
- 1500mg vial
Regulatory note
Glutathione is not FDA-approved for general wellness use. FDA has issued warnings about injectable glutathione marketed specifically for skin lightening, which is a different use from the antioxidant and hepatic-support research this sheet covers. Not on the July 2026 PCAC agenda.
What the Evidence Supports
Well established
Glutathione’s biochemical role is not in question. It is the principal intracellular antioxidant, essential to phase II hepatic detoxification conjugation reactions, and it regenerates other antioxidants including vitamins C and E. Depletion is a recognised feature of oxidative stress states, and IV glutathione has established clinical use in specific protocols, notably alongside cisplatin chemotherapy to reduce neurotoxicity.
Less established
Whether supplemental glutathione produces meaningful benefit in healthy adults for general wellness, energy or longevity is not well demonstrated. Skin lightening is a separate use with limited evidence, and it is the one FDA has warned about.
The bottom line
Well-characterised biology with a real clinical role. The principal intracellular antioxidant, central to phase II liver detoxification, and established in specific protocols. What it does inside a cell is not in dispute; how much a given dose shifts that is less well mapped.
Also in the Range
Compare with NAD+ in the cellular support category. Different pathways — glutathione is antioxidant defence and detoxification, NAD+ is energy metabolism and DNA repair.
