DETAILS

L-Glutathione Reduced Powder

(Reduced Glutathione Powder) is the active reduced form of a tripeptide compound formed by the peptide linkage of glutamic acid, cysteine and glycine. It is one of the most important endogenous antioxidants in the body. Its molecular structure contains a reactive thiol group (-SH), endowing it with strong free radical scavenging ability and redox regulation function.

FUNCTION

Powerful antioxidant to eliminate free radicals in human body

Reduced L-glutathione is the core active form of glutathione inside cells. It can directly bind and neutralize excess free radicals generated by ultraviolet radiation, pressure, strenuous exercise and metabolic activities. It prevents free radicals from attacking normal cells, slows down cell aging, and maintains the stable operation of internal circulation.

Support liver detoxification and protect hepatocytes

The liver is the main detoxification organ of the human body, and reduced glutathione is an essential substance for liver metabolic detoxification. It combines with harmful toxins, alcohol metabolites and chemical residues in the liver to convert them into water-soluble substances for excretion. It reduces toxic damage to liver cells, alleviates liver burden, and maintains normal liver physiological functions.

Inhibit melanin formation and brighten skin tone

Reduced glutathione can inhibit the activity of tyrosinase, the key enzyme for melanin synthesis in skin cells. It blocks the production and deposition of melanin, fades pigment spots, dullness and yellowish skin caused by ultraviolet rays and endocrine factors. Long-term reasonable supplementation helps even out skin tone, improve skin transparency and achieve bright, translucent skin.

Enhance body immunity and improve cell defense ability

Immune cells rely on sufficient reduced glutathione to maintain proliferation, differentiation and activity. It optimizes the vitality of lymphocytes and phagocytes, strengthens the body’s ability to resist external bacteria and viruses. It reduces the probability of fatigue, colds and low immunity caused by long-term staying up late, high work pressure and poor living habits.

Application

Raw material for oral skin-whitening health food

Reduced L-glutathione powder is a classic functional raw material for internal whitening supplements. It is compounded with vitamin C, collagen peptide, grape seed extract and other raw materials to produce whitening oral powder, solid drinks and effervescent tablets. It targets groups with dull skin, pigmentation and sun tanning, widely sold in beauty stores, cross-border health product channels and online skincare platforms.

Functional raw material for liver-protecting dietary supplements

This powder is used to develop liver-nourishing and detoxifying health products for people who drink frequently, stay up late and work overtime. It can be filled into hard capsules or pressed into tablets alone or matched with milk thistle extract, turmeric extract and B vitamins. Such liver-protecting tablets and capsules are supplied to pharmacies, physical health stores and professional nutrition brands.

High-end cosmetic additive for skincare raw materials

Food-grade and cosmetic-grade reduced glutathione powder can be added to serums, whitening masks, essence liquids and ampoules. It penetrates the epidermal layer to suppress melanin at the source, improve facial dullness and lighten acne marks. It is favored by mid-to-high-end professional skincare brands and beauty salon special line products as a safe brightening active ingredient.

Sports nutrition raw material for anti-fatigue fitness supplements

For fitness enthusiasts, athletes and people with high physical consumption, reduced glutathione powder is added to comprehensive recovery powder and anti-fatigue sports drinks. It eliminates exercise-induced free radicals, relieves muscle soreness and fatigue after high-intensity training, accelerates physical recovery, and maintains stable athletic state for long-term training and competitions.
