Is Too Much Omega 3 Bad For You?

Omega-3 is a polyunsaturated fatty acid that is found in high concentrations in fish such as Pacific herring, Chinook salmon and Pacific sardines, as well as flaxseeds and walnuts and their oils, according to the Linus Pauling Institute. Westerners are often deficient in omega-3 and overindulgent in omega-6, a fatty acid found in oils such as safflower and corn, as well as all animal flesh products.

The Omega-6 to Omega-3 Ratio

Inflammation is a necessary biological process that your body uses to help heal injuries and illness, but unchecked inflammation is associated with numerous diseases. Omega-3 fatty acids are known to decrease inflammation in the body, while omega-6 fatty acids promote it. The University of Maryland Medical Center explains that those who follow a Mediterranean style diet, which includes far more fish and far less meat, are less prone to cardiovascular problems. This result is related to the omega fatty acids represented by the relative diets. More fish and less meat means more omega-3 and less omega-6, thus helping keep inflammation in check.

Too Much of a Good Thing

As with most nutritional supplements, omega-3 fatty acids should be used prudently. An attempt to make up for the imbalances inherent to the traditional Western diet shouldn't result in a swing to the opposite extreme, as too much omega-3 can cause a number of health problems of its own.

Consequences

Some of the qualities that make omega-3 helpful for your heart, such as its ability to aid in the break down of blood clots, can also make it harmful for those with bleeding disorders. Very large doses of omega-3 may increase bleeding and bruising. Another concern is the presence of environmental toxins that can accumulate in fish flesh, though MayoClinic.com explains that fish oil supplements are unlikely to contain these contaminants.

Dosages

The American Heart Association states that you should consume your omega-3 fatty acids through food sources, by eating fish twice per week. If you have cardiovascular disorders, you may wish to supplement your diet with additional omega-3. The U.S. Food and Drug Administration generally regards a dosage of up to 3 g of fish oil per day as safe. Ask your doctor for recommendations regarding dosages, and avoid supplements that also contain omega-6 and omega-9, as omega-6 is already present in your diet, and omega-9 is readily produced by your body without any help from dietary supplementation.
