Fish Oil Supplements: Are They Worth It?
Fish oil supplements have long been praised for their potential health benefits, ranging from heart and brain health to joint support, improved vision, and a stronger immune system. However, a recent study suggests that these claims may be nothing more than hype and that consumers may be wasting their money. The study, led by Joanna Assadourian, a fourth-year medical student at UT Southwestern Medical School in Dallas, shed light on the misleading health claims made by fish oil supplement labels and questioned their effectiveness.
Assadourian points out that while large, randomized trials have already shown that fish oil supplements do not prevent heart disease in the general population, they continue to be one of the most commonly taken supplements. Out of curiosity, Assadourian and her team investigated the actual claims made on the labels of fish oil supplements. They analyzed data from 2,819 labels of on-market fish oil supplements and examined the frequency and types of health claims. The findings were quite surprising.
The study found that nearly 74% of the analyzed labels made at least one health claim, but only 19% of these claims were approved by the U.S. Food and Drug Administration (FDA), providing consumers with a clear understanding of any scientific uncertainty surrounding the claim. The remaining claims were general structure or function claims, such as “promotes heart health.” The most common assertions were related to promoting cardiovascular health.
Furthermore, the study revealed a significant variation in the daily doses of the essential omega-3 fatty acids, EPA and DHA, found in fish oil supplements. Nine percent of the analyzed brands included a daily dose of 2 grams or more of combined EPA and DHA. Worth noting is the fact that experts have not yet established daily dietary recommendations for these fatty acids, according to the Office of Dietary Supplements.

The popularity of fish oil supplements, especially among individuals over the age of 60, who often take them for heart health, is undeniable. However, Dr. Ann Marie Navar, an associate professor of medicine at UT Southwestern, advises patients to consider alternative investments. She suggests focusing on fresh vegetables, a gym membership, or medications for conditions like blood pressure or cholesterol, rather than relying on fish oil supplements.
Assadourian emphasizes the importance of consulting with healthcare professionals before making any decisions based solely on supplement labels. According to her, supplement labels can be confusing, even for the most well-informed consumers. Therefore, having a conversation with a physician or a registered dietitian is essential for accurate and reliable information.
These findings coincide with the opinion of Connie Diekman, a food and nutrition consultant and former president for the Academy of Nutrition and Dietetics. Diekman acknowledges that the evidence supporting the benefits of fish oil supplements is inconclusive. While consuming seafood, in general, can provide health benefits, it is not entirely clear whether the oil derived from fish is the decisive factor. Diekman advises individuals to discuss their dietary choices with healthcare professionals, who can guide them or refer them to reputable websites that provide accurate and trustworthy information.
Fish itself is a fantastic source of protein, low in saturated fats, and rich in omega-3 fatty acids. The American Heart Association recommends consuming fish at least twice a week, particularly fatty fish. However, for those who are not fond of the taste of fish or have dietary restrictions, there are alternative ways to incorporate it into their routine.
Diekman suggests starting with less fatty fish options that have milder flavors. Cooking the fish and letting it cool a little can also help mellow out the taste. Fish can be combined with pasta or mixed with vegetables to make it more palatable.
As for individuals who still choose to take fish oil supplements, Diekman emphasizes the importance of reading the list of ingredients. Many supplements contain additional substances beyond the desired omega-3 fatty acids, so it is crucial to ensure that the product contains what is expected and not unnecessary fillers.
While Diekman provides some perspective on fish oil supplements, Dr. Navar highlights the need for further research. Dr. Navar mentions ongoing placebo-controlled randomized trials, such as VITAL and ASCEND, testing the efficacy of fish oil supplements for heart disease prevention. These trials have not shown any benefit so far. Dr. Navar asserts that more research is necessary to understand how consumers interpret vague statements like “promotes brain health” and determine the most effective messaging to accurately convey the true benefits, or lack thereof, of fish oil supplements.
In conclusion, the study raises concerns about the misleading claims made on fish oil supplement labels and suggests that consumers may not be getting the benefits they expect. Patients are encouraged to consult with their healthcare professionals for personalized advice rather than relying solely on supplement labels. Fish itself, with its high protein content and omega-3 fatty acids, remains a valuable addition to a healthy diet. However, for those who are not fish enthusiasts, there are alternative ways to enjoy its benefits. As the research in this field continues, it is essential to rely on accurate information and seek guidance from trusted sources.
