Stearidonic acid (18:4ω-3) is a rare polyunsaturated fatty acid of the ω-3 series. In normal humans, it represents less than 0.25% of serum phospholipid fatty acids.1 It is present in certain natural oils such as echium and black currant seed, and to the extent that these oils are incorporated into nutraceuticals, stearidonic acid can become a significant polyunsaturate in the human diet. Stearidonic acid ethyl ester is an ester version of the free acid that is less water soluble, but more amenable for the formulation of stearidonate-containing diets and dietary supplements.
