Fish oil supplements have been touted as a miracle cure for various health issues, but the scientific evidence is not always clear-cut. While they do contain essential omega-3 fatty acids, the benefits of taking fish oil supplements are often exaggerated.
According to experts, eating fish rather than relying on supplements can provide numerous health benefits. Omega-3s in fish have been shown to reduce inflammation, lower blood pressure, and stabilize cell membranes. However, it’s unclear whether these benefits come solely from the omega-3s or a combination of factors such as diet, cooking methods, and serving styles.
In fact, some studies suggest that taking high doses of fish oil supplements may increase the risk of atrial fibrillation and other cardiovascular issues. Furthermore, many fish oil supplements are not consistently regulated, making it difficult for consumers to know what they’re getting.
Dr. Amelia Sherry notes that there is “some strong evidence” that fish oil can help people with pre-existing heart disease, but more research is needed to confirm these findings. In contrast, prescription fish oil is often more regulated and may be a better option for those with cardiovascular concerns.
To reap the benefits of omega-3s without supplements, experts recommend eating fatty fish as part of a balanced diet. This approach can provide numerous health advantages while avoiding potential side effects associated with supplements.
As cardiologist Dr. Stephen Kopecky puts it, “The story of a fish oil supplement is… a microcosm of our world. We find some food that’s beneficial for us, we say we know exactly what part is beneficial and we reduce it, desiccate it, put it in a pill, and sell it to you for 10 times as much money.”
