How Much Omega 3 Fish Oil Should I Take Daily?

Multiple factors cause Omega-3 daily doses to vary. When eating fatty fish, portion and Omega-3 levels affect how much to consume. Since medical experts recommend fresh fish sources of Omega-3 fish oil, the origins of the fish are factors. One's health is an important consideration for dosage guidelines.

The American Heart Association provides recommended Omega-3 daily doses.


According to the American Heart Association (AHA), Omega-3 fatty acids are essential fats that your body needs to function properly. The body does not make Omega-3 fatty acids. The main sources of supplemental Omega-3 are food and fish oil supplements. EPA and DHA are the types of Omega-3 that human beings need. EPA and DHA are found in wild ocean oily fish, including salmon, halibut, mackerel, and sardines. Omega-3 fatty acids are available in supplements. When considering how much Omega-3 fish oil to take daily, one must know how much a given source supplies.


Take some form of EPA and DHA Omega-3 fatty acids for its proven benefit for the heart. Daily doses also depend upon one's health. Always consult a physician for individual dosage guidance.

Fatty Fish

The AHA recommends healthy people eat oily fish (salmon, tuna, mackerel, herring and trout), at least twice a week. People with coronary heart disease should take about a gram of EPA and DHA daily. AHA recommends the source of EPA and DHA be from oily fish. Individuals may take fish oil supplements with the guidance of a physician. According to the AHA, individuals with high cholesterol may need to take 2 to 4 grams of EPA and DHA per day in supplement form with a doctor's guidance.

For Consideration

Mercury poison in fish and effects from fish farming are necessary considerations when purchasing salmon and other oily fish, rich in Omega-3 fatty acids. Dr. Andrew Weil recommends wild northern fish including, Alaskan salmon, Alaskan halibut, sardines, herring and mackerel. These fish are still abundant. The benefits of purchasing wild fish include purity from antibiotics, genetically modified organisms and pesticides. According to Dr. Weil, distilled fish oil supplements are acceptable alternatives to eating fresh fish. Like the AHA, Dr. Weil urges individuals to speak with their physician before starting an Omega-3 fish oil regimen of any kind.
