Our product is made in a GMP-approved factory with 3 built-in concentration systems and 4 extraction tanks (6 m³ each). Using HPLC, UV-Vis, and TLC analytical tools, each batch goes through strict quality checks. You get an 80-mesh white crystalline powder that is always in stock up to 100 tonnes and can be delivered quickly in 5 to 8 business days.

Our product meets world compliance standards for pharmaceutical, dietary supplement, and skin care uses. It is certified by ISO 9001, ISO 22000, HACCP, Kosher, and Halal.

What Makes L-Glutathione Reduced Powder the Master Antioxidant?

This is the biologically active, unoxidized form of the tripeptide made up of L-glutamate, L-cysteine, and glycine. What makes it so valuable is its "reduced" state. It has a free sulfhydryl (thiol) group that neutralises reactive oxygen species and helps cells get rid of waste.

This active form, unlike oxidised glutathione (GSSG), makes other antioxidants, like vitamins C and E, again. Biochemists call it the "master antioxidant" because of this.

It stops tyrosinase from working, which changes the production of melanin from dark eumelanin to lighter pheomelanin. This system gets rid of discolouration where it starts. It binds to heavy metals and toxins in liver-supporting products, making it easier for the body's natural metabolic processes to get rid of them.

Compared to chemical synthesis, our enzymatic fermentation method guarantees better chirality and fewer liquids left over. This means that your finished goods will be more biocompatible and absorb them faster.

Technical Specifications

Core Product Advantages for Your Formulations

Powerful Antioxidant Capacity

The highly reduced active structure has amazing abilities to donate electrons. Free radicals are quickly neutralised, which protects the active ingredients in your products from oxidative degradation while they're on the shelf.

Exceptional Purity and Activity

Our product is 99% pure, which was confirmed by HPLC, and it still has all of its biological action. The important thiol group is kept safe by the green purification technology we use, so your goods always give the same results.

Profile of Rapid Absorption

When compared to less pure options, our fermentation-derived powder is more bioavailable. It quickly joins cellular metabolic cycles, which means that its powers to improve skin tone, protect the liver, and boost the immune system show up faster in end users.

Industrial-Scale Stability

To deal with the hygroscopic problem, we use special storage and packing methods. Our technical team helps with formulations to keep glutathione intact in complicated mixtures by balancing pH and chelating transition metals.

Key Applications Across Industries

Dietary Supplements and Nutraceuticals

With our high-purity material, you can make high-quality supplements that whiten teeth and help the stomach. It meets the rising need for natural detoxification products, especially for people whose livers are overworked from stress in their daily lives.

Skincare and Cosmetic Formulations

L-Glutathione Reduced Powder is used by formulators to make improved creams for pigmentation, anti-aging, and brightening. Through its tyrosinase inhibition process, it makes skin tone more even and brighter.

Functional Food and Beverage

Boost the immune system by adding immune-boosting ingredients to your healthy foods and useful drinks. The powder dissolves easily in water (about 100 mg/mL), so it can be easily added to liquid mixtures without a lot of work.

Uses in Pharmaceuticals

Meet the strict USP and EP standards for raw materials used in pharmaceuticals. The specific rotation (-15.5° to -17.5°) and melting point (192-195°C) of our product make sure that the quality is always the same for medicinal uses.

Why Xi'an DN Biology Stands Out?

Full-Chain Quality Check

Every step is closely watched, from our combined planting base to the final packaging. We provide full traceability, third-party testing support, and free samples before shipping so you can check the quality before placing big orders.

Solutions for Flexible Manufacturing

We can meet your needs, whether you need 25 kg for testing a new product or several tonnes for mass production. Our OEM/ODM services let you make changes based on the recipe needs you have.

Rapid Delivery and Logistics

Once payment is confirmed, items that are in stock will be shipped within 7 days. To make your supply chain easier, we offer DDP shipping services and a number of other delivery options. For custom orders, the wait time for production is between 7 and 15 days.

Technical Support from Experts

Our team is available 24 hours a day, seven days a week to help you with formulation problems. We know that glutathione can be unstable, and we can help you find useful ways to buffer pH and bind metals in your goods.

FAQ

Q: In which high-end fields is L-Glutathione Reduced currently the mainstream application?

A: It is widely used in oral whitening dietary supplements, liver-protecting products, and immune-regulating nutritional products. It's also a core raw material in the high-end skincare field, where it improves dull skin and pigmentation. It repairs liver burden caused by staying up late and external damage while enhancing the body's immunity. The ingredient is highly favored in global health and beauty markets.

Q: What are the highlights of L-Glutathione Reduced in terms of absorption efficiency and efficacy?

A: Adopting green purification technology, the raw materials remain active and are absorbed by the human body quickly without easy inactivation. Compared with low-purity products, it rapidly participates in the human metabolic cycle. This allows functions like brightening skin tone, protecting the liver, and providing antioxidation to be fully expressed. The finished product effect is more stable and outstanding.

Q: What are the core advantages of the product?

A: Highly reduced active structure, strong antioxidant capacity, rapid absorption, and intact biological activity. Our enzymatic fermentation method ensures superior chirality and lower residual solvents compared to chemical synthesis, translating to higher biocompatibility in your formulations.

Q: How do you ensure product stability during storage and shipping?

A: We use specialized moisture-barrier packaging and provide detailed storage guidelines. Our technical team can recommend formulation strategies including pH buffering (maintaining acidic to neutral range) and chelating agents to prevent oxidation from transition metals.
