The popularity of consuming fish oil is due to its high content of omega 3, a fatty acid that is a protector of cardiovascular health. However, there is a great disparity of opinions about the properties and benefits of fish oil in our health. Likewise, there are notable discrepancies between theoretical studies and clinical trials. In any case, it should be considered as a dietary supplement and never as a substitute for any food or as a medicine in itself. It is a widely consumed dietary supplement around the world, just behind vitamins and minerals.
If you want to know what fish oil is, what it is for and its benefits, keep reading this article and you will get complete information.
What is fish oil for?
The fish oil dietary supplement is extracted from the fat of oily fish such as: tuna, herring, mackerel, sardines, salmon or trout. The consumption of this type of fish is considered essential for our body due to its contribution of omega 3 fatty acids and eicosapentaenoic acid (EPA), which are essential for cardiovascular health. Omega-3 also has anti-inflammatory properties that benefit those suffering from diseases related to arteriosclerosis and rheumatism. It also provides docosahexaenoic acid (DHA), to which the ability to reduce the level of triglycerides is attributed.
The combination of these acids is supposed to have the ability to strengthen the veins and arteries, in addition to helping to keep the blood free from clots, which is why they are considered a form of prevention of thrombosis, embolisms and strokes, as well as a treatment to lower blood pressure. However, it has more benefits and is used to improve more aspects of our health, as we will see below.
