Borage oils are extracted from the seeds of the European herb Borago officinalis and are distinguished by their content of γ-linolenic acid (GLA), an omega-6 polyunsaturated fatty acid, alongside palmitic, oleic, and linoleic acids. Valued in nutraceutical and functional-food applications, the oil is marketed in capsules and fortified products for its essential-fatty-acid profile. Because GLA-rich oils are highly unsaturated, processors must protect them from oxidation through nitrogen blanketing, opaque packaging, and antioxidant addition, and verify that pyrrolizidine alkaloid residues from the seed remain within regulatory limits.
