With so many different fish oil supplements to pick from, finding the right supplement may seem confusing. Fish oil contains high amounts of omega-3 fatty acids. The fatty acids are highly beneficial for heart and cardiovascular health. Before adding fish oil into your daily supplement and vitamin mix, discuss taking it with your doctor. Omega-3 fish may cause rare side effects in some people.
Ingredients
When choosing fish oil, carefully read the list of ingredients of each manufacturer. Fish oil contains two different types of fatty acids, eicosapentaenoic and docosahexaenoic, also referred to as EPA and DHA. Some fish oil brands may add a small dose of vitamin E into each gel cap to prevent spoilage. Read the list of ingredients and look for additional vitamin and minerals added into the fish oil mix. Though these vitamins and minerals are beneficial, if you are taking other supplements already containing your daily recommended dosage, you may be at risk of overdosing. MedlinePlus reports some brands may include extra iron, calcium and vitamins D and C.
Fish Types
Fish oil is commonly made from fatty fish, such as herring, tuna, sardine and mackerel. Avoid fish made from large, predator fish that are high in toxins, such as mercury. The fish with the highest amount of mercury include shark, tilefish, swordfish and king mackerel, advises the American Heart Association. Though these fish are not usually used to create supplements, it is important to be aware of the risks of consuming these fish. Only use a fish oil supplement where the type of fish is indicated on the label.
Contaminant-Free
Only take fish oil from a source that verifies the supplement is free of contaminants, advises the University of Maryland Medical Center. Look for third-party verification instead of statements made by the manufacturer. U.S. Pharmacopeia is a nonprofit group that examines nutritional supplements ingredients and contaminant levels. When purchasing fish oil, look for the label "USP Verified" to determine if the organization has reviewed the fish oil.
Enteric-Coating
If you are suffering from fishy aftertaste, switch to an enteric-coated version of the capsules. This type of supplement is commonly marketed as an "odor-free" option of the supplement, explains MayoClinic.com. Enteric-coating involves a special substance surrounding the fish oil, which does not digest until the capsule is in your intestines. Once in the intestines, you will notice a decreased occurrence of fishy burps and belching.
