L-Cysteine hydrochloride is a stable hydrochloride salt of the amino acid L-cysteine. You can think of it as a "packaged" version of L-cysteine, making it more stable and less susceptible to oxidation, making it easier to store and use. It is highly soluble in water and, once in the body, breaks down and exerts the physiological functions of L-cysteine.
L-cysteine is a conditionally essential amino acid, meaning the body can synthesize some, but supplementation is required in response to stress, illness, or specific conditions. Its most significant characteristic is the presence of a sulfhydryl group in the molecule, which is the source of many of its biological activities.

key Features
1.Key raw material for glutathione synthesis:
This is its most core function. Glutathione is the body's most important antioxidant and detoxifier, and L-cysteine is the rate-limiting raw material for its synthesis. Supplementing with L-cysteine hydrochloride can effectively increase glutathione levels in the body.
2.Powerful antioxidant and detoxification capabilities:
By increasing glutathione levels, it helps the body scavenge free radicals and mitigate oxidative damage. Its sulfhydryl groups can also bind to heavy metals (such as lead and mercury) and certain toxins, promoting their excretion from the body and playing a detoxifying role.
3.Promoting protein synthesis and tissue repair:
As an amino acid, it is one of the building blocks of protein synthesis and is crucial for maintaining healthy skin, hair, and nails.
4.Composition of keratin:
It is a key component of keratin, the primary protein found in hair and nails. The disulfide bonds in keratin are formed by two cysteine molecules, which contribute to hair's strength and elasticity.
In the healthcare sector:
It is used to treat drug-induced liver injury, alcoholic liver disease, viral hepatitis, and other conditions, as an adjunct to liver protection and detoxification. As a dietary supplement, it is used to enhance immunity, combat aging, and mitigate the side effects of radiotherapy.
In the food industry :
It is widely used in the baking industry. It breaks disulfide bonds in gluten, reducing dough elasticity and increasing extensibility, making bread softer, more voluminous, and easier to machine. It is also used in the production of meat flavorings, where it plays a key role in the Maillard reaction, producing an appealing barbecue flavor.
As a nutritional supplement:
It is added to foods to supplement amino acid nutrition.
In the cosmetics sector:
Skin care: Due to its antioxidant and glutathione synthesis properties, it is claimed to have whitening, spot-lightening, and anti-aging benefits. In hair care: It is a core ingredient in many perming solutions. The principle of perming involves first breaking the disulfide bonds in hair with a reducing agent (often containing cysteine) and then re-forming them with an oxidizing agent.
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
