Garcinia cambogia

Garcinia cambogia suppliers and sourcing guide

Garcinia cambogia (now Garcinia gummi-gutta) is a tree of southern India and Southeast Asia whose sour fruit rind is dried and used in cooking. For supplements, the dried rind is extracted with water and the hydroxycitric acid (HCA) is usually supplied as a calcium, potassium or mixed calcium-potassium salt, standardized to 50% to 60% HCA. Free HCA tends to convert to its lactone, so the salt form and lactone content matter.

Forms and grades of garcinia cambogia

Suppliers sell different products under the same name. Specify the one you need.

  • Dried fruit rind

    Sun- or smoke-dried rind used as a souring agent and as extraction raw material.

  • Calcium HCA extract

    Rind extract as calcium hydroxycitrate, commonly standardized to 50% to 60% HCA.

  • Potassium or calcium-potassium HCA

    More water-soluble salt forms for drinks and powders.

  • Rind powder

    Milled dried rind, not standardized.

What to check on the COA

Compare each result with your own specification when the lot arrives.

HCA assay (HPLC)
Total hydroxycitric acid and HCA lactone by HPLC, or by titration in older specs; the method and whether lactone is included should be stated.
Mineral content
Calcium and potassium by ICP-OES or titration to confirm the salt form.
Identity
HPLC or HPTLC fingerprint to confirm Garcinia rind origin.
Heavy metals
Lead, arsenic, cadmium and mercury, usually by ICP-MS, checked against the buyer's limits and Prop 65 exposure targets where relevant.
Microbiology
Total plate count, yeast and mold, E. coli and Salmonella. Raw herb powders carry more microbial load than extracts and may be steam treated, which should be stated on the COA.
Loss on drying
Moisture against the spec; salts can pick up water.

Storage, lots and expiry

Storage and shelf life

Keep garcinia extract sealed in lined drums in a cool, dry place; HCA salts are hygroscopic and cake once they absorb moisture. Reseal opened containers promptly. Shelf life or retest date follows the supplier's spec, with HCA and lactone rechecked at retest.

Lots and expiry dates

HCA content, salt ratio and lactone level vary by lot and process, so check each COA against the spec. Record the supplier lot, salt form, HCA result and retest date.

Regulatory status

Facts from regulators and standards bodies, each linked to its source.

This is general information, not regulatory advice. Status differs by country and by how the ingredient is used, so check the rules for your product and market.

Common forms include dried fruit rind, calcium HCA extract, potassium or calcium-potassium HCA and rind powder. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for garcinia cambogia include?

Expect hCA assay (HPLC), mineral content, identity, heavy metals, microbiology and loss on drying, each with its method, specification and result for that lot.

How should garcinia cambogia be stored?

Keep garcinia extract sealed in lined drums in a cool, dry place; HCA salts are hygroscopic and cake once they absorb moisture. Reseal opened containers promptly. Shelf life or retest date follows the supplier's spec, with HCA and lactone rechecked at retest.

What is the regulatory status of garcinia cambogia?

Health Canada's Malabar Tamarind natural health product monograph lists Garcinia gummi-gutta with the fruit peel as the source part. The same monograph covers extracts standardized to 50-60% hydroxycitric acid. The EU Novel Food status Catalogue entry for Garcinia cambogia (POL-NF-00374) concerns the fruit and lists it as not novel in food. A separate catalogue entry for hydroxycitric acid (POL-NF-00416) concerns its calcium salt and lists it as not novel in food supplements.
