The Controversy Surrounding Heart Health Claims on Fish Oil Supplements

A new analysis has found that fish oil supplement labels often make heart health-related claims without sufficient scientific evidence to support them, according to researchers from the University of Texas Southwestern Medical Center. The researchers reviewed data from fish oil supplement labels and found that the majority of them contained claims about cardiovascular benefits, despite a lack of trial data proving their efficacy. The researchers also discovered that the levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) varied between products. While some studies have found fish oil supplements to have no effect on heart health, others suggest that supplementation is beneficial. The researchers concluded that more research is needed to understand the relationship between fish oil and heart health.
