High-purity botanical extracts developed for the global health industry.
Redefining Nutritional Bioavailability through Precision Extraction
As the global wellness market pivots toward evidence-based preventive nutrition, Catechins—specifically Epigallocatechin Gallate (EGCG)—have emerged as a cornerstone of metabolic health, cardiovascular support, and antioxidant therapy. For global brands seeking reliable OEM Catechin supplement manufacturers, the challenge lies not just in sourcing, but in ensuring molecular stability and high bioavailability.
In this comprehensive white paper, we explore how Botanical Cube Inc. and its parent company, Xi'an Tianben Bioengineering Co., Ltd., are setting new benchmarks in the industry. Leveraging over 20 years of experience, we provide a vertically integrated solution from raw tea leaf selection to the final, standardized powder.
The synergy of raw material proximity and technological scale.
China accounts for over 40% of the world's green tea production. Our facilities in Shaanxi enjoy direct access to high-altitude tea plantations, ensuring that our raw materials are processed within 24 hours of harvest to preserve catechins from oxidation.
Unlike traditional solvent extraction, our factories utilize Supercritical CO2 Extraction and Membrane Separation Technology. This results in an EGCG purity of up to 98% with zero organic solvent residue.
By operating three massive production bases covering 100+ acres, we achieve economies of scale that allow us to provide premium ingredients at competitive wholesale prices without compromising E-E-A-T standards.
Benefiting from the solid foundation provided by its parent company, Xi'an Tianben Bioengineering Co., Ltd., Botanical Cube Inc. focuses on researching, developing, producing and selling healthy natural ingredients. With more than two decades of industry experience, it has become a leader in the field, specializing in providing high-quality plant extracts and customized solutions to global customers.
Our operations are supported by three entities - Xi'an Tianben Bioengineering, Botanical Cube Inc., and Shaanxi Tianben Kangyuan Biotechnology - which together process more than 3,000 tons of plant raw materials each year.
Established in 2012 in Sanyuan City, our first factory was a milestone. Over the decade, we have invested heavily in technology, training, and quality control. Today, this facility stands as a testament to our commitment to excellence in the botanical extraction industry.
Powder collection, crushing, sieving, mixing, and drying processes are all performed in a Class 100,000 cleanroom environment. Our operators strictly follow hygiene protocols and wear sterile gowns, masks and gloves to maintain product purity and safety.
This sterile environment ensures that our Catechin supplements are free from microbial contamination and environmental pollutants, meeting the highest food and pharmaceutical standards.
Adapting to the "Clean Label" and "Functional Food" Revolution.
Consumers are demanding transparency. Our OEM solutions provide non-GMO, organic-certified green tea extracts with no synthetic fillers. We utilize natural excipients like pea fiber or organic rice hull to maintain a clean ingredient list.
To overcome the bitter taste and poor stability of catechins in aqueous solutions, we offer nano-encapsulated catechin powder. This technology enhances intestinal absorption by up to 5x and allows for use in clear functional beverages.
We provide macro-level solutions by combining Catechins with other actives like L-Theanine for cognitive focus or Astaxanthin for advanced anti-aging effects, providing your brand with a unique market "Information Gain" advantage.
Tailored solutions for diverse market requirements.
Standardized EGCG capsules for weight management and metabolic health. Available in bulk powder or finished bottle formats for North American and European markets.
Water-soluble green tea polyphenols that remain clear and stable in acidic pH, ideal for the growing Japanese and Southeast Asian RTD tea markets.
High-purity Catechins for topical application to combat UV-induced oxidative stress, specifically formulated for the high-end skincare brands in Korea and France.
Expert insights for informed procurement decisions.
Our standardized Catechin powders have a shelf life of 24 months when stored in a cool, dry place. We use aluminum foil vacuum packaging to prevent oxidation and moisture ingress.
Yes. Many clients require Decaffeinated Green Tea Extract. We can reduce caffeine levels to below 0.1% while maintaining EGCG concentrations above 95%.
Every batch undergoes internal QC testing. Additionally, we work with third-party labs like SGS or Eurofins to provide COAs (Certificate of Analysis) for heavy metals, pesticide residues, and potency upon request.
For bulk powder, the MOQ is 25kg (one drum). For customized retail-ready packaging (capsules/sachets), the MOQ typically starts at 500-1000 units depending on the formulation complexity.
We prioritize sourcing from Rainforest Alliance Certified plantations and implement water-recycling systems in our Sanyuan production base to minimize environmental impact.
