One of the trusted Black Tea Extract Manufacturers, Al-Fiza Herbal, makes this product out of perfectly oxidised leaves of Camellia sinensis grown in the well-kept organic gardens of India. Validated for its flavonoid value and ensured with every batch by the HPLC analysis of the extract, which provides us with reliable biologically active ingredients for nutraceutical, pharmaceutical and functional food consumers in Indian and global markets. Some of the significant constituents of oxidised Camellia sinensis leaf include theaflavins, thearubigins, catechins, caffeine, gallic acid and flavonoids, which are the chief source of their antioxidative, cardiovascular, metabolic and antimicrobial action.

As the reliable Black Tea Extract Manufacturers in India, we control the oxidation process precisely, maximising theaflavin formation while preventing over-oxidation that degrades the thearubigin fraction. What makes this extract distinct from green tea is its oxidised compound architecture, catechins convert into theaflavins and thearubigins during processing, with theaflavin-3-gallate and theaflavin-3,3'-digallate showing stronger LDL oxidation inhibition than equivalent catechin concentrations in comparative research.
We are serving buyers as the experienced Black Tea Extract Suppliers in India, we report theaflavin and thearubigin content as separately verified figures on every batch CoA, not combined under a generic polyphenol total. Each consignment includes heavy metal analysis, pesticide residue data, caffeine content, moisture levels, and microbial compliance records provided without additional request.
As the authentic and certified Black Tea Extract Exporters in India, we supply this ingredient consistently across cardiovascular, antioxidant, and functional food markets internationally, where theaflavin-specific standardisation is increasingly becoming a non-negotiable purchasing requirement over generic tea polyphenol claims. We are supplying HPLC-approved theaflavin reports, Heavy Metal Certificates, pesticide screening & Plant Quarantine Certificate along with every consignment. Provide us with your specification, intended application, and target market, & our team will come back with a customised proposal.
