![]() And consumption of rancid oils is certainly not advisable for patients with high risk or existing CVD since they promote inflammation. In addition to concerns with the variable amounts of omega-3 fatty acid and the presence of other “unhealthy” oils, we also found that the beneficial omega-3s themselves were often oxidized or rancid due to poor manufacturing processes.As you know, saturated fats and their high caloric content are not recommended for patients with cardiovascular disease (CVD) or at high risk for CVD. When we investigated what other oils are in these products, we found that they included those that are not considered heart healthy, including saturated fats.The amount of beneficial omega-3s in these supplements often make up only one-third or less of the total oil in the product and levels can differ from what is advertised and even from lot to lot.What we have learned and published over the years has raised serious quality concerns, in 3 important ways: ![]() While many people do turn to fish oil dietary supplements to augment or replace fish in their diet, our laboratory has been studying the quality of these supplements to better understand if they are in fact a safe and effective alternative to fresh fish or even prescription omega-3 fatty acids. Many patients turn to fish oil supplements to gain the benefits of omega-3 fatty acids, but there are important considerations pharmacists should be aware of before recommending fish oil supplements to their customers. Instead, tilapia has more omega-6 fatty acids, which are considered proinflammatory and actually negate many of the benefits of omega-3s. For example, tilapia has become popular both for home cooks and on restaurant menus, but tilapia contains 10 times less omega-3 than salmon. Great sources of omega-3s include oily fish, such as salmon and mackerel, but unfortunately, not all fish are the same with respect to their omega-3 content. Omega-3 fatty acids are considered essential fatty acids as our bodies do not produce them so we must obtain them from the food we eat and other sources. However, findings from extensive research into omega-3s may be surprising.įor well over 10 years, my colleagues at Elucida Research and I have been investigating the biological properties of omega-3 fatty acids and how they protect the heart to prevent serious cardiovascular events, like heart attacks or strokes. Pharmacists appreciate the value of omega-3 fatty acids for patients with cardiovascular disease and fish oil supplements are a frequently suggested method for people to increase their intake of this important nutrient.
