The invention relates to compositions comprising fatty acid mixtures comprising very long chain unsaturated fatty acids. The fatty acids of the fatty acid mixture are isolated from natural oils. Particularly, the fatty acid mixtures comprise an enriched amount of both very long chain monounsaturated fatty acids (VLCMUFAs) and very long chain polyunsaturated fatty acids (VLCPUFAs). In one embodiment of the invention, the amount of cholesterol in the fatty acid mixture is minimised and a method for production is provided.
