Deep-sea fish oil: It contains linolenic acid, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which plays a very important role in maintaining the normal metabolism of human cell membrane. Deep-sea fish oil can reduce blood viscosity and platelet aggregation, thus reducing thrombosis. Deep-sea fish oil can also enhance the deformability of cells, and EPA can enhance the vasodilation ability in vivo. Therefore, deep-sea fish oil has antithrombotic and anti-atherosclerosis effects, which is helpful to prevent and treat coronary heart disease, arrhythmia, myocardial infarction and cerebral embolism.
