Glutathione is a tripeptide containing a γ-amide bond and a sulfhydryl group. It is composed of glutamic acid, cysteine, and glycine and is present in nearly every cell of the body. Glutathione helps maintain normal immune system function and has antioxidant and detoxifying properties. The sulfhydryl group on cysteine is its active group (often abbreviated as G-SH), allowing it to easily bind to certain drugs and toxins, giving it an integrative detoxifying effect.
Glutathione is not only used in pharmaceuticals but also as a base for functional foods, widely used in anti-aging, immune-enhancing, and anti-tumor functions.
Glutathione exists in two forms: reduced (G-SH) and oxidized (G-S-S-G). Under physiological conditions, the reduced form predominates. Glutathione reductase catalyzes the interconversion between the two forms. This enzyme's coenzyme also provides NADPH for the pentose phosphate bypass metabolism.

1. Powerful Antioxidant Effect (Fighting Free Radicals)
Glutathione directly neutralizes harmful substances such as free radicals and peroxides, protecting cell membranes, proteins, and DNA from oxidative damage. Oxidative damage is the root cause of aging and many chronic diseases.
2. Detoxification (Liver Detoxification)
Glutathione is a core substance in the liver's detoxification system (Phase II detoxification pathway). It binds to external toxins (such as heavy metals, pesticides, and drug residues) as well as harmful substances produced by metabolism, rendering them water-soluble and allowing them to be excreted through bile or urine.
3. Immune System Regulator
Mechanism: Glutathione is crucial for the proliferation and function of immune cells, especially lymphocytes. It helps the immune system fight infection and disease most effectively.
4. Boosting Energy Metabolism and Fighting Fatigue
Mitochondria, the "energy factories" of cells, generate a large number of free radicals when producing energy. Glutathione protects mitochondria from damage by these free radicals, ensuring efficient energy production.
1.Clinical Drugs
Glutathione drugs are widely used clinically. In addition to utilizing its sulfhydryl groups to chelate poisoning with heavy metals, fluoride, mustard gas, and other toxins, it is also used as a treatment or adjunct therapy for hepatitis, hemolytic diseases, keratitis, cataracts, and retinal diseases.
2.Antioxidant Effects
Glutathione, as an important antioxidant in the body, scavenges free radicals. Human red blood cells contain high levels of glutathione, which plays a crucial role in protecting the sulfhydryl groups of proteins on red blood cell membranes in a reduced state and preventing hemolysis.
3.Food Additives
Adding glutathione to food can have unexpected benefits:

Our packing method is 1KG/Aluminium bags, 25kg/drum
For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
