A vegetable-based lipid composition comprising: (i) docosahexaenoic acid (22:6n-3) in an amount of from about 15% to about 35% by weight of the total fatty acid content of the composition; (ii) eicosapentaenoic acid (20:5n-3) in an amount of up to about 5% by weight of the total fatty acid content of the composition; (iii) α-linolenic acid (18:3n-3) in an amount of from about 10% to about 20% by weight of the total fatty acid content of the composition; (iv) oleic acid (18:1n-9) in an amount of from about 20% to about 40% by weight of the total fatty acid content of the composition; and (v) palmitic acid in an amount of up to about 1.5% by weight of the total fatty acid content of the composition; wherein components (i) to (v) are each independently provided in the form of a fatty acid, a fatty acid salt, a fatty acid ester or a salt of a fatty acid ester; wherein the lipid composition is obtainable by a process comprising transesterification and distillation of a vegetable-based lipid; wherein at least 70% by weight of the lipids in the composition are derived from plant sources, and wherein: (i) said plant sources are oilseeds; or (ii) said plant sources are selected from the group consisting of Brassica sp., Gossypium hirsutum, Linum usitatissimum, Helianthus sp., Carthamus tinctorius, Glycine max, Zea mays, Arabidopsis thaliana, Sorghum bicolor, Sorghum vulgare, Avena sativa, Trifolium sp., Elaesis guineenis, Nicotiana benthamiana, Hordeum vulgare, Lupinus angustifolius, Oryza sativa, Oryza glaberrima, Camelina sativa, and Crambe abyssinica.
