Wholesale Green Tea Extract Manufacturer Suppliers & Factory

Industry-Leading Active Ingredients, Advanced Biotechnology, and Global Standard Regulatory Compliance for Premium Nutritional, Cosmetic, and Pharmaceutical Brands.

The Science and Industrial Demands of Premium Green Tea Extract

Green tea extract, derived from the leaves of the Camellia sinensis plant, is globally recognized as one of the most potent natural antioxidants. The therapeutic benefits of green tea extract are primarily attributed to its high concentration of polyphenolic compounds, specifically monomeric flavan-3-ols known as catechins. Among these catechins, Epigallocatechin Gallate (EGCG) exhibits the strongest free-radical scavenging capacity and metabolic modulation capabilities.

For global B2B procurement officers in the dietary supplement, functional food, and cosmetic industries, choosing a wholesale green tea extract supplier goes far beyond simple pricing. The critical factors that dictate product efficacy and commercial success include the standardization of key chemical markers, the absolute control of solvent residues, the elimination of heavy metal contamination, and the strict absence of pesticide residues (meeting both USP and European Pharmacopoeia standards).

Key Active Phytochemical Fractions in Green Tea Extract

  • Polyphenols (Standardized up to 98%): The total antioxidant pool consisting of simple catechins, complex gallated catechins, and phenolic acids.
  • EGCG (Standardized up to 95%): The primary bio-active component responsible for thermogenesis, cellular health, and neuroprotection.
  • L-Theanine: A unique amino acid that crosses the blood-brain barrier to promote cognitive relaxation and focus.
  • Decaffeinated Formulations (Caffeine < 0.5%): Essential for nighttime dietary formulations and cardiovascular health applications where stimulation is unwanted.

Research & Development Innovation

UniCare invests 10% of our annual net profit in research and development. In addition to optimizing and developing the existing natural plant extraction process, we have also established a professional R&D department for natural fermentation products. By increasing investment in natural fermentation products, we try to break through the traditional processes and disrupt industry development.

UniCare has deep cooperation with Beijing University of Chemical Technology in the field of fermentation, jointly developing and transforming the new raw materials of pharmaceutical, cosmetic, and natural health products into mass-produced products.

Raw Material Planting and Procurement

In order to control raw materials more efficiently and with higher quality, a raw material procurement system has been established, which extends procurement to every piece of planting land and can trace the raw materials of each batch of products. The storage of raw materials is operated according to the advanced quality management system process, and the content of active ingredients, moisture, ash, heavy metals, pesticide residues and other items of raw materials are strictly controlled.

At the same time, in order to further ensure the high quality of important products, UniCare cooperated with planting farmers to establish ginkgo leaf planting bases, epimedium planting bases, phellodendron planting bases, olive leaf planting bases, etc. Some of these bases are planted strictly in accordance with the GACP management model. In addition, we cooperate with seedling research and development companies to develop high-content seedling cultivation, and cultivate better seedlings through hybridization or gene optimization, so as to continuously reduce unit costs to benefit users.
