Garcinia cambogia fruit-rind extract standardised for hydroxycitric acid, including water-soluble calcium, potassium and magnesium salt systems.
Standardised HCA extracts and a complete family of water-soluble single, double and triple mineral salts.
Garcinia cambogia — Malabar tamarind — yields hydroxycitric acid (HCA), a weight-management active extracted from the dried fruit rind. CTA manufactures HCA extracts standardised from 50% to 70%, with assay by HPLC.
Our distinctive capability is the HCA mineral-salt platform. Free HCA is hygroscopic and unstable; converting it to mineral salts gives a stable, water-soluble, formulation-friendly active. CTA produces single-salt (calcium or potassium), double-salt (potassium–calcium) and triple-salt (potassium–magnesium–calcium) grades, including a 70% water-soluble grade. Garcinia is also cultivated on the group's own Rawther Plantations estate, giving a backward-integrated supply line.
CTA supplies Malabar Tamarind across multiple grades. Custom specifications are developed against a documented buyer requirement.

All values are typical specifications and are confirmed batch-by-batch on the Certificate of Analysis. Custom specifications can be developed against a buyer's documented requirement. Values are indicative and to be confirmed by CTA's technical team before publication.
CTA holds a documented HCA salt-conversion library, supported by double- and triple-salt process know-how:
A documented process library is what separates a speciality product from a commodity — it makes grades reproducible and lets CTA develop a custom specification with confidence.
Statements describe traditional use and the role of the active in normal body function. They are structure–function statements and not claims to diagnose, treat, cure or prevent any disease.
Weight-management capsules, tablets, effervescents and drink mixes.
Standardised HCA actives for proprietary weight-support formulations.
Water-soluble HCA salts for ready-to-mix and ready-to-drink formats.
HCA salt systems combined with functional minerals.
Garcinia HCA extracts are permitted under FSSAI and are widely traded internationally. Salt-system identity, moisture limits and grade documentation are provided on enquiry.
Note: grades, marker percentages and regulatory status are indicative and to be confirmed by CTA's technical and regulatory team before publication.
Free hydroxycitric acid is hygroscopic and tends to lactonise, losing activity. Converting it to calcium, potassium or mixed mineral salts produces a stable, water-soluble active suited to tablets, sachets and beverages.
A single salt pairs HCA with one mineral (calcium or potassium). Double salt uses potassium and calcium; triple salt adds magnesium. Multi-mineral salts improve solubility and deliver functional minerals alongside the HCA.
Garcinia is cultivated on the group's Rawther Plantations estate and through the buy-back network, supporting traceable supply.
