Description
Cold-pressed and refined seed oil from borage (Borago officinalis, also called starflower), the highest natural commercial source of gamma-linolenic acid (GLA, C18:3 omega-6), standardized to a minimum 20% GLA content with premium grades reaching 24%.
Pale yellow to amber clear oil with a mild characteristic aroma. GLA content at twice the level of evening primrose oil delivers the same daily GLA dose at half the softgel count, supporting premium positioning in concentrated softgel formats.
We supply food-grade and pharmacopoeial Borage Oil from manufacturers in China holding ISO, Halal, Kosher, and organic certifications relevant to the product and production. Standard 20% GLA, premium 22% GLA, and high-grade 24% GLA versions are available.
Common market grades include Refined Borage Oil 20% GLA (the dominant commercial grade), 22% GLA premium, 24% GLA top-tier, and Pyrrolizidine-Alkaloid-Tested grades for European market compliance.
Bulk and reduced-MOQ shipments. Batch-level COA covering fatty acid profile (GC), GLA content, pyrrolizidine alkaloid residue, peroxide value, acid value, heavy metals, and microbiology.
Introduction
Borage (Borago officinalis) is an annual herb native to the Mediterranean, cultivated since Roman times as a culinary and medicinal plant. Commercial seed oil production began in the 1980s as the supplement industry pursued higher-concentration GLA sources than evening primrose oil. Modern cultivation is concentrated in the U.K., Canada, China, and New Zealand.
The seeds are cold-pressed or solvent-extracted, with refining calibrated to preserve GLA and to remove the trace pyrrolizidine alkaloids that the borage plant produces in leaves and flowers. Modern refining and analytical testing keep pyrrolizidine alkaloid residues well below the limits set by the EU Committee for Medicinal Products for Human Use and by the German BfR, with compliant material targeting non-detectable levels.
The fatty acid profile is unusual among commercial seed oils, with GLA at 20% to 24% (twice the level of evening primrose), linoleic acid at 35% to 40%, and notable contents of oleic and erucic acids. The GLA enrichment is the basis of commercial positioning in concentrated softgel formats.
Regulatory status is broad. Borage oil is recognized as a conventional food in the U.S. and is permitted as a food supplement in the EU subject to pyrrolizidine alkaloid limits. China permits the product under health food regulations.
Commercial positioning targets consumers who want concentrated GLA dosing in fewer softgels, where borage offers a clear product-format advantage over evening primrose oil. The clinical literature on GLA in atopic dermatitis, rheumatoid arthritis, and women's hormonal complaints applies to both source oils, and the choice between them is typically a product-design decision rather than an indication-driven decision.
Where it is used
- Concentrated GLA softgels positioned around the highest per-capsule GLA dose

- Skin health and atopic dermatitis support; clinical evidence overlaps with evening primrose oil
- Inflammatory-balance and joint health formulations; rheumatoid arthritis clinical literature
- Cardiovascular and metabolic health products
- Cosmetic and skincare formulations including anti-aging serums
- Pediatric atopic dermatitis support products in regulated markets
- Pet supplements for skin and coat support
- Functional food fortification in regulated dose ranges
