Chia seed oil

Chia seed oil suppliers and sourcing guide

Chia seed oil is pressed or extracted from the seeds of Salvia hispanica, a mint-family plant grown mainly in South America and Mexico. About 30% of the seed is oil, and alpha-linolenic acid (ALA) usually makes up the largest share of its fatty acids. Brands buy it as cold-pressed oil for softgels and liquid supplements, as refined oil for foods, or as a powder.

Forms and grades of chia seed oil

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

  • Cold-pressed oil

    Mechanically pressed and filtered oil, the usual grade for supplements, often sold against a minimum ALA level.

  • Supercritical CO2 extracted

    Oil extracted with CO2 rather than a press, offered by some suppliers as solvent-free with a lighter color.

  • Refined oil

    Refined and deodorized oil with milder flavor for food applications.

  • Organic

    Oil from certified organic seed, a common request for supplement brands.

  • Powder

    Oil microencapsulated on a carrier for dry blends and capsules.

What to check on the COA

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

Fatty acid profile
Fatty acid composition by GC of the methyl esters (AOCS Ce 1-62 or an equivalent ISO method), reported as percent of total fatty acids; ALA is the figure buyers compare.
Peroxide and anisidine values
Peroxide value (AOCS Cd 8b-90) for primary oxidation and p-anisidine value for secondary oxidation, often combined as TOTOX; these show how fresh the oil is at release.
Free fatty acids
Free fatty acids or acid value by titration (AOCS Ca 5a-40 or Cd 3d-63), which rises with poor seed handling, hydrolysis and age.
Heavy metals
Lead, arsenic, cadmium and mercury by ICP-MS, reported against the supplier's specification or the limits of the target market.
Pesticide residues
Multi-residue pesticide screen by GC-MS/MS and LC-MS/MS, relevant for cold-pressed and organic grades where nothing is removed by refining.

Storage, lots and expiry

Storage and shelf life

Keep sealed under nitrogen, cool and dark; refrigerate after opening. High ALA makes the oil oxidize fast once air gets in, so buy in container sizes that match usage. Shelf life is set by the supplier specification, with peroxide and anisidine values retested on aged stock.

Lots and expiry dates

ALA level and color vary with growing region and crop year, so record the fatty acid profile and oxidation values from each lot COA. Rotate first-expiry, first-out.

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.

Frequently asked questions

What forms of chia seed oil can brands buy?

Common forms include cold-pressed oil, supercritical CO2 extracted, refined oil, organic and powder. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for chia seed oil include?

Expect fatty acid profile, peroxide and anisidine values, free fatty acids, heavy metals and pesticide residues, each with its method, specification and result for that lot.

How should chia seed oil be stored?

Keep sealed under nitrogen, cool and dark; refrigerate after opening. High ALA makes the oil oxidize fast once air gets in, so buy in container sizes that match usage. Shelf life is set by the supplier specification, with peroxide and anisidine values retested on aged stock.

What is the regulatory status of chia seed oil?

Health Canada's Fixed Oil Products - Oral monograph lists chia seed oil, from the seed of Salvia hispanica, as a permitted ingredient. That monograph requires the statement 'Refrigerate after opening' for products containing chia seed oil, except encapsulated products. The EU Novel Food status Catalogue entry for Salvia hispanica (POL-NF-00681) covers the seeds, seed oil and partially defatted seed powders and gives them the status authorised novel food.
