Hallo! Well I did a small research and a found a lot of benefits of fish oil. Apparently fish oil contains important Omega-3 fatty acids , most notably eicosapentaenoic acid (EPA) and decosahexaenoic acid (DHA). These Omega-3 fatty acids are believed to have health benefits ranging from reducing the risk of heart attack and coronary heart disease to combating depression, bipolar disorder and schizophrenia. Consumption of dietary fish or fish oil supplements can lower triglycerides-a certain type of blood fat-and increase "good" cholesterol, while slightly thinning the blood. All of these factors help reduce the risk of heart attack. Omega-3 fatty acids are not only good for the heart; they also help to reduce inflammation. Heart disease, cancer, autoimmune diseases, psoriasis, and Alzheimer's, for example, are characterized by increased levels of pro-inflammatory markers. Fish oil is also effective in reducing the symptoms and pain of arthritis. Morning stiffness and joint tenderness was shown to decrease with regular intake of fish oil supplements. As if the benefits of fish oil on heart health and arthritis were not enough, it is believed that fish oil also helps with anti-aging as well. Fish oil has also been shown to be beneficial to pregnant women and the unborn child. Not only is fish oil beneficial to physical health, fish oil is also beneficial to mental health. The Omega-3 fatty acid, DHA, increases the production of the protein LR11, thus decreasing the amount of toxic "plaques" and helping to prevent the occurrence of Alzheimer's. Fish oil does not only help prevent Alzheimer's. It also helps to prevent mental illnesses such as depression, bipolar disorder, and schizophrenia. Hopefully these informations will help you.
