Doubts about the effectiveness of omega 3 supplements in cardiovascular problems

They are sold in supermarkets, herbalists and even gym shops, without the need to provide any kind of prescription to the vendors. They don't just convince nutritionists or doctors that they often opt for a balanced diet before recommending them. And the scientific evidence doesn't support them. Scientists already know that supplements food neither prolong life nor make us smarter. Now, a new meta-analysis published in the journal JAMA Cardiology concludes that omega 3s also do not protect people with cardiovascular problems


For research, experts from the University of Oxford (UNITED), in collaboration with institutions in countries such as Canada, Italy or the Netherlands, analysed 10 clinical studies involving a total of 78,000 people with histories doctors of coronary problems, heart attacks and diabetes. Over four and a half years, scientists compared the differences in the health of participants by giving them omega 3 supplements or a placebo. The results were clear: there was no difference between the people who took the supplements and those who took the placebo.

Unlike what was thought and contrary to the recommendations of the American Heart Association, which advises patients who have suffered a myocardial infarction to take fatty acid supplements, meta-analysis concludes that these supplements do not reduce the risk of coronary heart disease, heart attacks or other types of cardiovascular disease. In fact, administered food supplements showed no improvement in health


Omega 3 supplements thus join a list of food supplements that do not meet your sales slogan. Other examples are those that are marketed to improve cognitive abilities and memory, where the scientific community recommends "not throwing money away." Nor do those who claim to extend life, and some, such as those used for bodybuilding, can even lead to problems related to fertility and erectile function.
