Glutathione is a three-amino-acid molecule your cells already make. It's often called the body's master antioxidant because it's the one cells lean on most to handle oxidative stress.

Research looks at its role in detoxification pathways and immune-cell function. It shows up across a lot of different tissue models for that reason.

This 1200 mg vial is third-party tested — the Certificate of Analysis is published on this page. Supplied strictly as a research material. Not for human or veterinary use.

High-dose glutathione, excellent purity
The 1200mg concentration is ideal for our oxidative stress research. HPLC confirmed 98.6% purity with no significant oxidized glutathione (GSSG) contamination. The reduced form was well preserved thanks to proper lyophilization and argon gas sealing.
Good value for the concentration
At 1200mg per vial, this is one of the more cost-effective glutathione options available from Canadian suppliers. Reconstitution with BAC water produced a clear solution. Shipping to Winnipeg was 5 days via Xpresspost in plain packaging.
Solid antioxidant research compound
We have been using this L-Glutathione in our redox assay panels. Consistency has been good across two orders. The lyophilized cake is compact and dissolves readily. Would appreciate batch-specific CoA documents included with each shipment rather than one generic one.
