What should I avoid while taking fish oil?

While you are taking fish oil, it is important to avoid eating foods high in fat, sugar, or cholesterol. Unhealthy foods work against the triglyceride-fighting effects of fish oil and reduce its effectiveness. Fish oil should be used in addition to a healthy diet and exercise routine, as overall health is the best way to control high blood pressure, cholesterol, and triglyceride levels. Also, avoid alcohol during your treatment because it raises triglyceride levels and can make your symptoms worse. Avoid taking large doses of fish oil at a time, as that may cause excessive or prolonged bleeding. The U.S. Food and Drug Administration (FDA) declared up to three grams of fish oil daily to be Generally Regarded as Safe (GRAS). If you suspect you have overdosed, call your doctor for further instruction.
