Glutathione 600mg

Glutathione 600mg is a tripeptide compound composed of glutamic acid, cysteine, and glycine, and is one of the most important endogenous antioxidants in the human body. Its core function is to neutralize free radicals and protect cells from oxidative damage. By directly scavenging reactive oxygen species (ROS) and reactive nitrogen species (RNS), glutathione helps slow cellular aging, supports liver detoxification, and maintains the normal functioning of the immune system. Because its oral absorption is affected by digestive enzymes, high-quality supplements often use the reduced form (GSH) or combine it with vitamin C to improve bioavailability. Glutathione is widely used in anti-aging, skin whitening and fading dark spots, and liver protection.

1. Powerful Antioxidant and Cell Protection

Glutathione 600mg is one of the body's most essential endogenous antioxidants, directly neutralizing free radicals and reactive oxygen species (ROS), reducing oxidative stress damage to cell membranes, proteins, and DNA. Simultaneously, it can regenerate other antioxidants (such as vitamin C and vitamin E), forming a long-lasting antioxidant network, protecting mitochondrial function, and fundamentally slowing down the cellular aging process.

2. Melanin Inhibition and Skin Brightening

By inhibiting tyrosinase activity, glutathione can interfere with key steps in the melanin synthesis pathway, promoting the conversion of eumelanin to pheomelanin, thereby reducing melanin production and deposition. Long-term supplementation helps to lighten dark spots, even out overall skin tone, and achieve a whitening effect from the inside out.

3. Promotes Liver Detoxification and Metabolism

Glutathione 600mg is one of the most important cofactors in the liver's secondary detoxification process, participating in the binding reaction of exogenous substances such as heavy metals, drug metabolites, and environmental pollutants, converting them into more water-soluble forms for excretion. Maintaining adequate glutathione levels is significant for protecting hepatocytes and reducing the burden on the liver.

4. Immune Regulation and Neurological Health Support

Glutathione can regulate lymphocyte proliferation and differentiation, enhance the activity of natural killer cells (NK cells), and help the body maintain normal immune defense capabilities. In the nervous system, it plays a positive role in maintaining cognitive function and long-term nervous system health by reducing oxidative stress levels and decreasing nerve cell damage and apoptosis.

After supplementation with glutathione precursor, in the subgroup with higher baseline oxidative stress levels, total glutathione levels increased from 819.7 mg/L to 905.4 mg/L (P=0.016).

一.Detailed Explanation of Each Step

1. Strain Preparation

Production strains are activated on solid plates for 24 hours, then incubated in shake flasks for 25-35 hours to obtain seed culture.
Key controls: strain activity, aseptic technique, medium ratio, temperature.

2. Fermentation Culture

The seed culture is inoculated into a fermenter (5%-10% v/v) and incubated at 28-35℃ for 18-24 hours, with precursor amino acids and promoters added at the appropriate time to enhance glutathione accumulation.
Key controls: pH, dissolved oxygen, temperature, C/N ratio, feeding strategy, induction timing.

3. Cell Disruption and Separation

The collected cell precipitate is disrupted by high-pressure homogenizer or ultrasonication to release glutathione, followed by centrifugation or filtration to collect the supernatant.
Key controls: separation efficiency, cell yield, disruption rate, temperature, clarity.

4. Purification and Drying

Glutathione in the supernatant is adsorbed onto a cation exchange resin, eluted via gradient elution to remove impurities, then concentrated and freeze-dried or spray-dried to obtain a white crystalline powder.

Key controls: resin selection, elution conditions, flow rate, temperature, final product moisture.

二.Key process indicators

1.Packaging Material Characteristics

• Vials

Using pharmaceutical-grade borosilicate glass vials, exhibiting excellent chemical stability and low-temperature resistance. This material has a low adsorption rate for glutathione, minimizing product loss on the container surface.

• Rubber Stoppers

Using butyl rubber stoppers, providing excellent sealing performance and low water and air permeability. The stoppers are pre-treated to withstand temperatures as low as -20°C without hardening or cracking due to freezing.

• Aluminum-Plastic Caps

Using aluminum-plastic composite caps, which can be sealed manually or automatically. After sealing, a highly airtight sealing system is formed, effectively preventing the entry of external moisture and microorganisms.

2.Storage Conditions

• Recommended Temperature: -20℃±5℃
• Light Protection: Store away from light and direct UV exposure.
• Dryness Requirements: Store in an environment with relative humidity <35%.
• Avoid Repeated Freeze-Thaw Cycles: The product is recommended for single use after thawing; repeated freezing and thawing are not advised.
