Glutathione 1500mg

Glutathione 1500mg is a key antioxidant naturally found in the human body, its core function being to protect cells from damage caused by free radicals, toxins, and inflammation. It directly participates in the liver's detoxification process, helping to metabolize drugs and pollutants, and also regulates melanin production, thus being used in skin-whitening products. Glutathione levels naturally decline with age or increased stress. While oral supplements are convenient, their absorption efficiency is relatively low, often requiring the addition of vitamin C to improve utilization; in contrast, injectable supplements have higher bioavailability.

1. Antioxidant Defense: Directly scavenges free radicals, protecting cells from oxidative damage. Glutathione 1500mg is one of the most important natural antioxidants in the human body, and it also helps restore the activity of vitamin C and vitamin E, allowing them to continue to function.

2. Liver Detoxification Support: As a key cofactor in the liver detoxification system, it helps metabolize drugs, alcohol, and environmental toxins. Glutathione is found in the highest concentration in the liver, and its level directly affects the body's detoxification efficiency.

3. Skin Tone Regulation (Whitening Mechanism): Reduces melanin production by inhibiting the activity of tyrosinase, while guiding the melanin synthesis pathway from dark to light types. This is a physiological regulation, unlike surface exfoliation or bleaching.

4.Stability Design: The product is in its reduced active form, where the thiol group (-SH) is the key structure for its antioxidant effect. The formulation has been optimized to ensure that it remains active and is not prematurely oxidized during storage and transportation.

• Those with high oxidative stress (e.g., those who frequently stay up late, engage in high-intensity exercise, or are exposed to polluted environments)
• Those who need liver support (e.g., those who drink alcohol or take medication long-term)
• Those who wish to brighten their skin tone and lighten pigmentation
• Middle-aged and elderly individuals (glutathione levels naturally decline after age 30)

1.Raw material testing: Quality control upon entry into the factory

Any batch of raw materials that does not meet any of the following criteria (purity ≥98%, moisture ≤5%, HPLC characteristic peak verification) will be returned to the supplier and will not be included in the production process.

2.Process Control: Real-Time Monitoring During Production

Once raw materials enter production, we set up process control (In-process QC) at key checkpoints.

The purpose of process control is early detection and early intervention, preventing issues from carrying through to the finished product stage.

3.Finished Product Testing: Comprehensive Inspection Before Shipment

Each batch of finished products must pass the following full set of tests before release:

1. Content Testing: The actual glutathione content must be within 90%-110% of the labeled amount (i.e., 1350-1650 mg/capsule).
2. Microbiological Limits: Total aerobic bacteria count, total mold and yeast count, and E. coli (not detectable).
3. Heavy Metal Testing: Lead, arsenic, mercury, and cadmium must comply with USP or EP pharmacopoeia standards.
4. Solvent Residue: The residual amount of organic solvents used in the production process must be below the safety limit.
5. Stability Testing: Accelerated testing to simulate shelf life to confirm that the active ingredient has not significantly degraded.

If any item fails to meet the requirements, the entire batch of products must be scrapped or reworked and will not be allowed to enter the market

4. Testing Equipment: Hardware Capability Guarantee
Our partner factories are equipped with the following core testing equipment to ensure the accuracy of test data:

All of these instruments are regularly calibrated and participate in proficiency testing to ensure that test results are traceable and reproducible.

Our R&D capabilities are built upon deep collaboration with high-quality suppliers, primarily reflected in the following three aspects:

1. Supplier Selection
Our glutathione raw materials and finished products are supplied by Chinese pharmaceutical companies with international certifications such as GMP and FDA, with core production areas located in Shandong, Hubei, and Shanghai. All partner factories undergo three rounds of screening: qualification review, on-site inspection, and verification of export records.

2. Formulation and Process Involvement
We don't passively accept supplies; we actively participate in formulation design:

• Synergistic Logic: Glutathione 1500mg combined with Vitamin C utilizes a regeneration mechanism to extend the active period.
• Stable Process: We require raw material suppliers to use the reduced active form and prevent premature oxidation during production through nitrogen protection and low-temperature drying.
• Packaging Suitability: We use light-proof, airtight packaging to ensure stable potency over a 36-month shelf life.

3. Quality Verification Mechanism
We have established a three-tiered quality control system:

• Supplier Self-Inspection: Each batch provides a Certificate of Analysis (CoA) verifying purity ≥98%.
• Support for Third-Party Sampling Inspection: We commission independent testing by SGS or Intertek for cross-validation of data.
• Arrival Re-inspection: We sample each batch upon arrival to confirm that it has not deteriorated during transportation.
