L-Glutathione Reduced(GSH)
CAS No.: 70-18-8
What’s the L-Glutathione reduced?
L-Glutathione reduced (GSH) is a naturally occurring tripeptide found in cells as an endogenous antioxidant that scavenges oxygen free radicals. It is a cofactor for certain enzymes and has influence in the rearrangement of protein disulfide bonds and the reduction of peroxides.

Glutathione
How Reduced Glutathione Works?
Its another name is GSH, works by neutralizing free radicals and reactive oxygen species in the body. It plays a crucial role in maintaining overall health and protecting cells from oxidative damage. It exists in two forms: reduced form (GSH) and oxidized form (GSSG). The ratio of GSH to GSSG is important for its proper functioning.
Glutathione peroxidase enzymes rely on GSH to neutralize hydrogen peroxide, a harmful reactive oxygen species. Additionally, it works synergistically with vitamins C and E to enhance overall antioxidant activity in the body.
It’s worth noting that its levels can decline with age, making supplementation important for optimal health. Taking a dietary supplement or a glutathione supplement can help boost glutathione levels, supporting overall health and immune function.
Let’s Sum Up
In conclusion, it plays a crucial role in maintaining cellular health and protecting against oxidative damage. As a powerful antioxidant, it helps neutralize harmful free radicals and supports various cellular processes, including detoxification and immune function.
