A composition of long-chain polyunsaturated fatty acids containing at least 80% by weight of eicosapentaenoic acid (EPA, C20:5 n-3) and/or docosahexaenoic acid (DHA, C22:6 n-3) and at least 3% by weight of n-6 fatty acids, particularly C20:4 n-6 and C22:5 n-6, is reported. For a better chemical and biological characterization of the composition, the content of other C20, C21 and C22 n-3 acids different from EPA and DHA is preferably reduced to less than 3% by weight. In the composition all said acids are present in the form of free acids, or their salts, or C1-C3 alkyl esters. The described composition is useful for the production of a dietetic or pharmaceutical preparation useful for treatment of conditions sensitive to the action of EPA and DHA, particularly in subjects potentially exposed to bleeding problems or to problems caused by coagulation defects. |
