All You Need to Know about Omega-3 Fish Oils (4 mins)

If you research fish oils, you’ll find out that they are one of the most popular supplements. Fish oils provide many health benefits, but it’s the omega-3 fatty acids fish oils contain that make them such a powerhouse. Eating fatty fish is one of the best ways to get plenty of omega-3s. But what if you don’t like fatty fish? Or what if you don’t eat it very often? You may want to consider taking omega-3 fish oils as a supplement just for the potential health benefits.

What are omega-3 fish oils?

The three types of omega-3 fatty acids:

  • ALA (Alpha-linolenic Acid) – ALA is present in plant-based sources like soybean, canola oils, and flaxseed.
  • EPA (Eicosapentaenoic Acid) – EPA is only present in oily fish like tuna and salmon.
  • DHA (Docosahexaenoic Acid) – DHA is only found in oily fish like tuna and salmon.

The body does not make ALA which is what makes it classified as an essential omega-3 fatty acid. This means it must be obtained through your diet or supplements. EPA and DHA are not “essential” since they are produced from ALA. However, the process of making EPA and DHA from ALA is not an efficient one. It is not a reliable way to get adequate amounts of DHA and EPA.

EPA and DHA help regulate different biological processes in the body including the inflammatory response, brain function, and different metabolic signaling pathways. DPA and DHA are omega-3 fats found in fish, phytoplankton, and some animal products.

How much omega-3 fish oil do I need?

According to the American Heart Association, two servings of fish each week is recommended for those who do not have a history of heart disease. Cold water wild fish like salmon, herring, tuna, mackerel, and sardines contain the high amounts of omega-3 fatty acids that are good for you. For those who have already received a diagnosis of heart disease, talk to your healthcare provider about how much omega-3 fish oil you should consume. Most recommend one gram of EPA +DHA daily. If you don’t care for fish, or have a difficult time getting enough, a fish oil supplement is a great option. 

Individuals who are being treated for high triglycerides need a lot more omega-3 fatty acids. Usually, a doctor will recommend an omega-3 fish oil supplement. If your healthcare provider recommends a fish oil supplement, they usually want you to take in two to four grams of EPA+DHA daily.  Some researchers suggest that this amount of fish oil can help lower triglyceride levels as much as 35% in some people.
