However, scientists have not been able to prove its supposed benefits. In fact, in an article published in the magazine JAMA Cardiology, researchers at the University of Texas Southwestern Medical Center in Dallas say that the marketers of these supplements continue to promote them with exaggerated claims. According to the same article, for which 2,819 fish oil supplements were analyzed, “the results suggest that further regulation of claims made on fish oil supplement labels may be necessary to prevent consumer misinformation.” .
Fish oil has two omega-3 fatty acids, EPA and DHA. These can be found in walnuts, fatty fish (salmon, for example) and flax seeds. According to researchers, patients can obtain these fatty acids through their diet and not necessarily through the use of supplements.

There are currently two qualified health claims in the United States regarding the potential for fish oil supplements to treat or prevent disease issued by the Food and Drug Administration (FDA). One is related to coronary disease and the other to blood pressure.
In the publication of JAMA Cardiology, the researchers say they found qualified FDA health claims in only 19% (399). Of the rest, more than 80% carry mild claims such as “supports the heart, mind and mood” and “promotes heart health”.
According to Ann Marie Navar, a co-author of the study, for The Washington Post, “It has not been consistently shown in high-quality trials that taking more fish oil supplements leads to better performance or disease prevention.”

The researchers acknowledged, however, some limitations in their analysis, such as that they only studied supplements from the 16 most influential brands of fish oil and the information on their labels. In addition, that in nutrition studies there is another series of variables to take into account, such as health conditions, diet, sleep patterns, among others.
But articles Studies have already shown that these supplements do not improve patient outcomes. For example, a rehearsal found that in the case of patients with diabetes, the risk of a cardiovascular event was not significantly different between those taking and those not taking omega-3 supplements.
