Fish Oil vs. Omega-3: The Key Differences Explained

Fish Oil

This may result in fish oil being exactly, what its name suggests, being extracted from fish tissues in the form of oil. It's a rich source of two important omega-3 fatty acids and two specific PUFA which are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) [Ref].

The benefits of fish oil are numerous due to these essential nutrients. However, it should be pointed out that as much as 70% of fish oil is composed of the other types of fats known as omega-3s, the vitamins D and A account for the remaining percentage.

It is extracted from the body of fatty fish such as herrings, sardines, anchovies as well as mackerels. The specialised factor of EPA and DHA has made it a preferred supplement given that many individuals find it hard to make adequate intake through diet alone.

The list of fish oil’s advantages is rather impressive [Ref]. It has been cited that it may be good for the heart [Ref], decreases inflammation, boosts the brain’s function and may help people with certain mood swings [Ref]. But there are also downsides such as individual interactions and the taste and the smell of fish oil are not very pleasant for some people [Ref].

Omega-3

Omega-3s are the category of polyunsaturated fatty acids which have an essential importance to almost every function in living organisms [Ref]. There are three main types of omega-3s [Ref]:

• Alpha-linolenic acid (ALA): It is found mainly in the plant sources flax seeds, chia seeds and walnuts.
• Eicosapentaenoic acid (EPA): Known to be present mostly in fish and seafood products.
• Docosahexaenoic acid (DHA): Also primarily located in fatty fish and seafood.

ALA is deemed necessary since the body cannot synthesize it, and therefore, it is acquired through food products. However, our bodies are not very efficient at converting ALA into EPA/DHA therefore, it is recommended to get EPA and DHA directly from food sources or from supplements.

Fatty acids have numerous health benefits, thus omega-3 fatty acids are connected with numerous health benefits. These are widely recognized to play a role in maintaining the health of the heart, and Brain function. It is also important here to mention that they may also assist in inflammation reduction and may have something to do with mood stabilisation [Ref].

What is the Difference Between Fish Oil and Omega-3?

Is Fish Oil the Same as Omega-3

Fish oil and omega-3 are easily mixed up, but they are not identical. Omega-3s describe a class of essential fatty acids that includes ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Eating these is crucial for your heart, brain, and eye health. Most of the ALA content is in plants, yet EPA and DHA are primarily available in fish and seafood.

Fish oil is taken from the tissues of fish such as salmon, sardines, and mackerel and includes a lot of EPA and DHA. But it lacks ALA, the sole omega-3 that our bodies are not capable of producing. Even though fish oil is a rich source of EPA and DHA, there are other ways you can get these fats.

Those who don’t eat fish can get DHA from algal oil, which comes from plants. The fact that the body converts plant ALA into omega-3s inefficiently means that you can’t depend on plants alone for these essential fats.

Fish oil gives you a big dose of EPA and DHA, but the right dosage is important. Experts typically recommend 250–500 mg of combined EPA and DHA daily for most healthy adults, though individual needs may vary. In addition to fish oil, you can take plant-based supplements to support your body’s omega-3 cells.

What Experts Say About Fish Oil & Omega 3?

Dr. Alice Lichtenstein, a Gershoff Professor of Nutrition Science and Policy, and Director, Cardiovascular Nutrition Lab at Tufts University, says that, "While fish oil is a rich source of EPA and DHA, it's important to consider individual dietary preferences and health conditions when choosing between fish oil and other omega-3 supplements."

Which is better: Fish Oil or Omega-3?

Thus, it is clear that, although fish oil is a rich source of omega-3s, not all omega-3s originate from fish oil. This is then the main difference between the two.

Fish oil and especially, fatty acids EPA and DHA are beneficial for the body. Omega-3, however, can be sourced from different kinds of supplements. While they may derive from fish oil, they can also come from algal oil, which is sourced from vegetables or krill oil [Ref].

As far as the issue of absorbability is concerned, omega-3s as found in fish oil in the form of triglycerides may be absorbed better than those in omega-3 supplements which are in the form of ethyl esters [Ref]. However, this can also differ in the certain product and how the formulation works.

Some of the important aspects that one has to consider when selecting the benefits include the following; When deciding between fish oil and omega-3 supplements, consider:

• Dietary preferences: If you eat plenty of oily fish (salmon, tuna, sardines) twice a week, you likely get enough omega-3s and may not need supplements. Opt for fish oil supplements if you don't eat much fish. Omega Fish Oil Gummies by WOWMD provide a convenient alternative for those who need to supplement fish oil. If you are a vegetarian or a vegan, you must take omega-3 supplements derived from plants.
• Sustainability: Not all fish oil production is environmentally friendly and good. However, the advice would be to opt for products that come from sustainable sources.
• Purity: Fish oil has some side effects like it can contain some materials like heavy metals sometimes. Select products that have undergone purification and have been tested for quality by other companies.
• Cost: Fish oil in this sense is usually cheaper than the other omega-3 supplements on the market.

For the general population, either using fish oil or omega-3 typically would be good for them. According to the American Heart Association [Ref], people should consume fatty fish at least twice a week or think about incorporating fish oil supplements if they do not eat fish.

Supplementation with DHA may be useful for pregnant women and children as this nutrient is necessary for the development of the fetal brain and cognitive function in early childhood [Ref].

Maintaining optimal levels of omega-3 during pregnancy and breastfeeding may reduce the risk of postpartum depression. A 2018 review even indicated that fish oil supplements could also be beneficial to some individuals.

But remember to follow the dosage instructed by the doctor to avoid any side effects to the mother or fetus.

To increase your omega-3 intake, fish such as salmon, pollock, canned light tuna, and catfish are excellent options, whereas you should stay away from fish with mercury concentrations, such as shark or king mackerel. As usual, you should always first consult with your physician before taking any supplements when pregnant or breastfeeding.

Some people have observed a problem of fishy smell on their breath after taking this supplement, the problem can be solved by going for enteric-coated capsules, or choosing good quality fish oil gummies, or one can refrigerate the supplement.

Opinions of Specialists and Latest Studies
