  • Patent number: 10485779
    Abstract: This invention relates to an oil composition, preferably obtained from a copepod, and the use thereof to reduce accumulation of visceral fat and counteract impairment of heart function caused by obesity inducing Western diets. The oil composition of the present invention can thus be used to reduce abdominal obesity and improve glucose tolerance and thus to reduce the risk of obesity related diseases such as but not limited to type 2 diabetes or cardiovascular disease, or to prevent or treat such diseases.
    Type: Grant

  • Patent number: 9820958
    Abstract: This invention relates to a biological oil composition, preferably obtained from a copepod, most preferably the copepod Calanus finmarchicus and the use thereof to prevent or treat formation of atherosclerotic plaques and hence development of coronary heart disease. The composition comprises the same marine n-3 polyunsaturated fatty acids (PUFAs) generally regarded as being responsible for the anti-atherosclerotic effect of marine oils, namely EPA (C20:5n-3 eicosapentaenoic acid) and DHA (C22:6n-3 docosahexaenoic acid). However, quite unexpectedly, it has been found that the oil composition of the present invention has a remarkably higher ability to prevent formation of atherosclerotic plaques than what can be attributed to EPA and DHA alone, and moreover, unlike EPA and DHA alone it has a notable blood cholesterol lowering effect.
