|
Finished product efficacy upgrading |
Conventional powder has insufficient absorption and unstable activity; high-stability and high-absorption modified grades become brand upgrading necessity |
|
Scene diversification demand |
Portable, liquid, chewable dosage forms put forward higher requirements on raw material taste, solubility and stability |
|
Market homogenization breaking |
Ordinary 98% powder market is highly competitive; customized modified specifications form effective technical barriers |
|
Beauty & liver health track growth |
Global oral beauty and sub-health liver maintenance demand continues to expand, driving raw material technical iteration |
As a core endogenous antioxidant raw material, reduced glutathione maintains a steady compound growth rate of 8.82% in the global market. The industry is gradually eliminating low-value synthetic raw materials, and natural fermentation high-purity glutathione has become the mainstream choice for mid-to-high-end health and beauty brands.
Conventional glutathione powder has inherent industrial limitations such as easy oxidation, poor stability and single application form.
Through physical modification, stability optimization, taste improvement and high-absorption delivery system upgrading, raw materials can adapt to diversified dosage forms such as liquid beverages, portable sticks and chewable tablets, effectively improving finished product stability, user experience and product competitiveness.
As a manufacturer and R&D institution focusing on natural fermentation active ingredients, KEEP has stable mass production capacity of standard 98% fermentation glutathione, and provides full-dimensional customized technical services including powder modification, stability adjustment, high-absorption upgrading and multi-active compound formulas, providing systematic and professional raw material technical support for global brand antioxidant, liver health and oral beauty product upgrading and iteration.
