The 18 carbon a-linolenic acid (ALA) has not been shown to have the same cardiovascular benefits as DHA or EPA.Currently, there are many products on the market that claim to contain health-promoting "Natural Omega 3", but contain only ALA, not EPA or DHA. These products contain mainly plant oils and must be converted by the body to create DHA, and are therefore less effective. DHA and EPA are made by marine microalgae. These are then consumed by fish and accumulate to high levels in their internal organs. The United States Environmental Protection Agency issues fish consumption advisories to empower Americans to avoid toxic mercury levels in certain fish and shellfish while still reaping the health benefits of consuming fish and shellfish.

People with certain circulatory problems, such as varicose veins, may benefit from such supplements containing EPA and DHA, which stimulate blood circulation, increase the breakdown of fibrin, a compound involved in clot and scar formation, and, in addition, have been shown to reduce blood pressure. Evidently, n-3 fatty acids reduce blood triglyceride levels,and regular intake may reduce the risk of secondary and primary heart attack.A systematic review of studies prior to 2005 showed that ALA does not confer the cardiovascular health benefits of EPA and DHA.

Some potential benefits of Natural Omega 3  have been reported in conditions such as rheumatoid arthritis and cardiac arrhythmias.

There is preliminary evidence that EPA supplementation, either with DPA or medication, is helpful in cases of depression There is also preliminary evidence that supplementation with ALA, EPA, and DHA, alone or in combination with n-6 fatty acids, can reduce anxiety.The New York Times, however, reports that at least one study has not found a connection between depression in heart patients taking Sertraline and daily supplements containing two grams total of EPA and DHA during a ten-week period.

Some research suggests that fish oil intake may reduce the risk of ischemic and thrombotic stroke, although large amounts may actually increase the risk of hemorrhagic stroke (see below): Lower amounts are not related to this risk; 3 grams of total EPA/DHA daily are generally recognized as safe (GRAS) with no increased risk of bleeding involved and many studies used substantially higher doses without major side effects (for example: 4.4 grams EPA/2.2 grams DHA in 2003 study.
