L-Glutathione (Reduced) for Research
Technical Overview
L-Glutathione is a naturally occurring tripeptide made of three amino acids, glutamine, cysteine and glycine, and one of the body’s most important antioxidants. It protects cells from oxidative stress and is essential to detoxification, immune function and maintaining the integrity of many body systems.
Research applications
- Antioxidant protection: its capacity to neutralize free radicals and reduce oxidative stress at the cellular level.
- Detoxification and liver research: its role in removing toxins and heavy metals and supporting liver function.
- Immune function: its role in immune system activity.
- Cellular health and aging: maintaining healthy cellular function and limiting oxidative damage.
- Skin research: protection against oxidative damage and support of collagen synthesis.
Mechanisms under study
A central role of L-Glutathione is controlling reactive oxygen species (ROS), by-products of normal cell activity. When ROS build up, they can damage proteins, fats and DNA; glutathione helps maintain the balance that keeps cells healthy, which makes it a reference compound in oxidative stress research.

Storage Instructions
Handling and Storage Tips:
- On arrival, store the sealed vial at −20 °C, protected from light and moisture.
- For short-term storage (days to weeks), refrigeration at 2–8 °C is acceptable.
- Lyophilized peptides tolerate room temperature for short periods, such as during shipping.
- Let the vial reach room temperature before opening, to avoid condensation.
- Once reconstituted, keep refrigerated at 2–8 °C and avoid repeated freeze–thaw cycles.
