Magdalena Perelló, cardiologist: "Omega-3 may be one of your heart's best allies, but not all are created equal."

Taking care of your heart isn't just a matter of exercising. Diet plays a fundamental role in preventing cardiovascular disease, and in this area, Omega 3 has earned a prominent place. This was recently explained by cardiologist Magdalena Perelló, who sent out a clear message on social media: this type of healthy fat can make a big difference to heart health, but taking just any supplement isn't enough. You have to choose wisely.

"Omega-3 can be one of your heart's best allies," she assures. However, she adds an important warning. "Be careful, not all are the same," she explains in the video. In accessible language, the specialist explains the keys to understanding why this fatty acid is so beneficial and how to identify a good product among the wide variety on the market.

The cardiologist wanted to remind us that Omega 3 is a substance she frequently recommends, especially to those who don't consume enough oily fish in their diet. This type of fish—such as salmon, mackerel, or sardines —is a natural source of these fatty acids, but it's not always included in weekly menus. "If you don't consume enough oily fish, an Omega 3 supplement can help," she explains.

And what are the benefits? Perelló summarizes them in three main pillars: reduction of triglycerides, control of silent inflammation that can damage arteries, and protection against the risk of heart attack and other cardiovascular diseases. "It helps reduce triglycerides, control the silent inflammation that damages our arteries, and also protects against the risk of heart attack," he explains.

However, she insists that not all supplements are equally effective. One of the most common mistakes among consumers is purchasing an Omega-3 supplement without looking at the details on the label. According to the expert, there are two key elements to consider: the concentration of EPA and DHA, and the chemical form of the supplement.

"Make sure it has a high concentration of EPA and DHA, and that it's in the form of re-esterified triglycerides," she says. This latter form, she assures, offers better absorption by the body, which increases its effectiveness.

Another key aspect is purity. In the video, Perelló referenced the IFOS five-star seal, an international standard that certifies the quality of Omega-3 supplements. This seal guarantees that the product is free of heavy metals, contaminants, and other substances that could diminish its therapeutic value or even be harmful. "Of course, it must guarantee purity, like the specified IFOS five-star seal," he emphasizes.

The cardiologist also emphasized the importance of scientific support. In a market rife with miracle products without medical endorsement, Perelló recommends relying only on supplements with serious studies backing their effectiveness . "If you're going to supplement, choose a quality Omega 3 with scientific backing," she concludes.
