Glutathione (GSH) is a tripeptide composed of glutamic acid, cysteine, and glycine. It is a core natural antioxidant in human cells, widely present in almost every cell.
Core Advantages and Functions:
* **Powerful Antioxidant and Anti-aging:** GSH is the most important redox buffer in cells, directly neutralizing and scavenging free radicals, protecting cell membranes, proteins, and DNA from oxidative stress damage. It also synergistically regenerates vitamin C and vitamin E in the body, maintaining cell vitality and delaying aging.
* **Liver Detoxification and Metabolic Support:** As the body's "ultimate detoxifier," GSH binds to heavy metals, drug metabolites, and alcohol toxins in the body through its active sulfhydryl group (-SH), converting them into water-soluble complexes for excretion, thereby reducing the burden on the liver and protecting liver cells.
* **Immune Regulation and Cell Survival:** It maintains the reducing environment within lymphocytes, promotes T cell proliferation, and enhances the activity of natural killer (NK) cells, bidirectionally regulating the immune system. Furthermore, it is a crucial link between metabolism and cell fate, participating in energy metabolism and protecting mitochondrial function. Skin Whitening and Spot Reduction: GSH can inhibit the activity of tyrosinase, block the melanin synthesis pathway, and reduce existing dark melanin to lighter-colored substances, showing significant effects in improving melasma and brightening skin tone.
Storage Conditions: Store powdered raw materials in a sealed, light-proof container at 2-8℃ for long-term storage; keep away from moisture, high temperatures, and direct sunlight to prevent oxidation and inactivation; prepare aqueous solutions immediately and use immediately, do not store for extended periods. Store in smaller containers to minimize frequent opening and exposure to air.
Precautions:
Route of Administration: Intravenous/intramuscular injection must be performed in a medical institution; oral administration is not suitable as a substitute for intravenous treatment of severe liver disease.
Contraindications: Contraindicated in patients with hypersensitivity to glutathione or excipients; use with caution in intravenous administration in asthmatic patients (rarely induces bronchospasm).
Adverse Reactions: Occasionally, rash, itching, nausea, and injection site pain may occur; anaphylactic shock is rare.
Special Populations: Safety data are limited in pregnant/lactating women and children; physician evaluation is required.
Co-use Reminder: Can be used in combination with common hepatoprotective drugs, but not recommended to mix with Vitamin K₃ or Vitamin B₁₂ in the same bottle (incompatibility).
