It is recommended to eat at least two servings of fish per week. A Norwegian study finds that if you follow this recommendation, taking omega-3 supplements will not provide added protection for your heart.
According to a study published in the American Journal of Clinical Nutrition, adults with heart disease do not benefit from taking omega-3 supplements if they eat a certain quantity of fish.
The new study shows that only patients with a low daily dose of omega-3, found in fish, nuts and certain vegetables, may reduce the risk of heart disease.
Lead researcher Mari Manger said: "Based on data from this and previous studies also in other countries, we think that it is relevant to say that most cardiac patients who are well medically treated and eat at least a certain amount of fish per week, probably will not benefit from taking omega-3 supplements."
Omega-3 supplements are therefore not very useful. U.S. authorities have also asked the FDA to better inspect the quality and safety of omega-3 supplements.
The study followed 2,400 Norwegians who were taking cholesterol drugs. Those who took omega-3 supplements did not avoid heart problems.
However, a high level of omega-3 in the body is not harmful to your health.
