The Best Fish Oil Supplements for 2023, According to Dieticians

Best Fish Oil Supplements

Fish oil is a fantastic source of omega-3 fatty acids. They offer several health benefits. There are several varieties of omega-3 supplements, each with unique constituent combinations and sources. They also come in a variety of forms, such as Gummies, liquids, and capsules.


Polyunsaturated fatty acids of the omega-3 variety are essential for many body functions, including inflammation as well as heart, immune, and brain health.

There are three different kinds of omega-3 acids:

  1. Eicosapentaenoic acid (EPA)
  2. Docosahexaenoic acid (DHA)
  3. Alpha-linolenic acid (ALA)

Fish contains the omega-3 fatty acids EPA and DHA, both of which have physiological effects. To absorb the nutrients, your body transforms ALA from plant meals into EPA and DHA (2Trusted sources).

Taking a supplement may be a quick and easy way to enhance your intake of omega-3 fatty acids if you don’t often eat fish or fish oil. Continue reading to see our top picks for the best 11 fish oil supplements.

What advantages does fish oil have?

Fish oil is a fantastic source of omega-3 fatty acids. They offer several health benefits. Omega-3 fatty acids have anti-inflammatory properties, and chronic inflammation is known to contribute to a range of ailments, including heart disease. Triglyceride levels are a key risk factor for heart disease, and EPA and DHA may help reduce them. Omega-3 fatty acids are crucial for eye growth and have the ability to treat dry eye disease, thus they also have a big effect on eye and visual health.

Omega-3 fatty acids are also essential for keeping the brain healthy. They are essential to ensuring that the baby’s and young child’s brains develop in the best possible way.

The risk of stroke and mental damage may be decreased for those who take omega-3 supplements.

What we do after making a choice?

When choosing the top fish oil supplements, we considered the following elements:

Vetting: Each item on the list has been checked to see if it adheres to Healthline’s ethical and professional standards, including but not limited to:

  • respecting the rules established by the Food and Drug Administration (FDA) on legal health claims and labelling specifications
  • Made in facilities that follow the most recent FDA-approved best manufacturing practises (CGMPs). FDA
  • created by reputable medical businesses that adhere to laws, ethics, and standards that set the industry

Quality: We examined the production and testing procedures in addition to the quality of the ingredients. The companies that manufacture the products we select provide open guarantees of dependability, such as having other laboratories evaluate their supplements.

A source of fish oil smaller fish often have lower mercury levels than larger fish, thus we recommend supplements with their fish oil.

Price: Our items are offered in a range of price points.

1. Rosita Cod Liver Oil

This is a brand-new item, and many integrative health blogs have featured it. It has one of the most flavourful, freshest flavours you’ve ever tasted. The flavour profile of the product is comparable to that of fine sushi restaurants’ premium salmon roe. You can taste and feel how fresh everything is. Rosita is a great alternative for people who want to maintain a healthy diet. For people with VDR genes who cannot take supplements with high amounts of vitamin D, the Rosita product is also a natural source of vitamin D and K. Think about the benefit of being able to administer the medication precisely because the product is accessible in liquid form rather than capsules. 443 mg of EPA and 605 mg of DHA are present in one tablespoon of Rosita product. The fish was caught off the coast of Norway and is a wild fish.

2. Nordic Naturals ProOmega-D

The ProOmega-D product came to our attention after a thorough examination into the cognitive benefits of fish oil, particularly for those with traumatic brain injuries. Although we also enjoy the Ultimate Omega product, patients with brain traumas have received help from ProOmega-D in clinical settings. The levels of total Omega 3 and EPA/DHA are equal. The “professional version” of Ultimate Omega is allegedly ProOmega-D. ProOmega fish oil is verified for analysis on every box and bottle, much like the other Nordic Naturals goods, ensuring its potency, purity, and freshness.

3. Nordic Naturals Ultimate Omega

Nordic Naturals’ Maximum Omega Nordic Naturals Ultimate Omega fish oil has some of the highest concentrations of EPA/DHA in a single serving of all the products tested this year. Nonetheless, one of Nordic Naturals’ greatest strengths is that its Certificates of Analysis are straightforward to obtain, which is one of the reasons it is ranked so highly in a few positions on this list. Omega-3 products from Nordic Naturals are all accompanied by Certificates of Analysis. The potency, freshness, non-GMO status, and lack of radionuclide action are all confirmed. Below is an example of how to find a lot of numbers on the back of a Nordic Naturals bottle (right by the expiration date).

After receiving an identification number for your lot, go to the Nordic Naturals website to complete the form and get the batch’s Certificate of Analysis (COA). The Certificate of Analysis is anticipated to include your lot number, the date of bottling or expiration, any unusually low levels of oxidation, heavy metals, or environmental pollutants, as well as the dates of such events.

Nordic Naturals seems to be as confident in the efficacy and purity of their products, hence we would want to see them obtain IFOS certification.

4. Nordic Naturals Omega Curcumin

Omega Curcumin, a fish oil supplement containing curcumin, N-acetylcysteine, and glutathione, is added to the traditional Nordic Naturals mix. If you want the omega-3 supplement to have an additional anti-inflammatory effect, this is an excellent substitute to consider. Glutathione and curcumin may be difficult to absorb due to their low bioavailability. As a result, they are frequently used in liposomal products. The issue with these goods is that they typically contain unhealthy fats rich in omega-6 acid as nutrition, which is why this is a problem. By using omega-3 fatty acids instead of less expensive phospholipids, which can enhance TMAO and other inflammatory markers, glutathione and curcumin’s bioavailability is boosted.

Equal amounts of the other components are utilised. While most people would likely benefit from starting with 150 mg of glutathione and 200 mg of NAC, 400 mg of curcumin is a terrific amount for therapeutic purposes.

5. Carlson the “Very Finest” Fish Oil

The Carlson Fish Oil brand is advised to consume two soft gels or 700 mg, simultaneously with a meal. The purity of Carlson’s particular concentration of Norwegian fish body oils, which are derived from deep cold-water fish, is guaranteed by an independent FDA-registered laboratory (anchovy, sardine, as well as mackerel).

The capsule with the real flavour on the outside—sweet, possibly from the glycerin—could be useful if you take five of these each day, but some people might find it a little off-putting.

6. Orthomega 820 Capsules

Orthomega provides the highest amount of EPA and DHA per soft gel (as well as being the most expensive; each tablet costs about $1), although the recommended dosage is only one soft gel daily. Also, only Orthomega uses anchovies as its main source of fish oil; other manufacturers use a variety of species. Also, their antioxidant mixture includes rosemary extract.

It tastes delicious, is a little expensive, and contains a lot of DHA and EPA.

7. Dr. Tobias Triple-Strength Omega 3 Fish Oil

Dr. Tobias’ Triple-Strength brand of fish oil contains a number of the best-selling components; including anchovies, herring, salmon, sardines, and mackerel (soy is another ingredient to be mindful of if you have allergies or sensitivities). The suggested dosage is two 1,000 mg soft gels taken with meals per day. The fish oil has been certified, tested, and processed using molecular distillation. It contains 800 mg EPA and 600 mg DHA per serving of two soft gels.

8. Nordic Naturals Omega-3

This was the only product we tested that wasn’t an e-liquid. You’ll instead take one chilled, refrigerated, and cold teaspoon (1,560 mg) of it every day with meals if you’re brave enough. It’s really simpler than you may imagine. In fact, one teaspoon of Nordic Naturals’ pure deep sea oil, which is derived from anchovies and sardines, has an astounding 745 mg of EPA and 500 mg of DHA. Certificates of analysis are also available upon request.

Nonetheless, those who are worried about saturated fats may consider the Nordic Naturals product’s liquid version. The product from Nordic Naturals has 8% of your daily recommended intake of saturated fat, while the majority of fish oil brands normally have between 1% and 3%.

9. NOW Ultra Omega 3 Fish Oil 

You only need one soft gel per day with Now Ultra Omega 3, which is a terrific feature (but you can use two). Although its DHA level is on the lower end, it has one of the highest quantities of EPA on our list. Moreover, this item employs concentrate rather than triglyceride, a substitute for fish oil that is of inferior quality.

10. Kirkland Signature Fish Oil

As Kirkland Signature is a well-known brand that you can find at Costco, you might want to choose this particular brand based on quantity rather than quality if you frequently use fish oil. This supplement costs about 6 cents a day. One soft gel containing 500 milligrams of DHA/EPA and mackerel, anchovy herring, menhaden, and sardine should be taken twice daily. The issue is that Kirkland’s nutritional label does not differentiate between the levels of EPA and DHA.

11. Nature’s Made Burp-less Fish Oil

Nature Made is one of the more well-known dietary supplements. They recommend taking their Burp-Free Fish Oil, which includes sardines and anchovies, twice daily with meals. Although the oil originates from Peru, it is bottled and put through quality inspections in America. Like Kirkland, Nature Made does not distinguish between the amount of EPA and DHA in the product.

The recommended daily intakes of ALA for men and women are 1.6 and 1.1 grammes, respectively.

Negative effects of fish oil that could be dangerous

The most well-known adverse effect of fish oil consumption is fishy burping. However, many “burpless” fish oil products on the market claim to lessen this unpleasant but beneficial side effect.

If you experience nausea or vomiting after taking the fish oil, make sure to check the expiration date. The deterioration of the oil might cause rancidity. Utilize the supplement with food to reduce any negative side effects.

The bottom line

There are several varieties of omega-3 supplements, each with unique constituent combinations and sources. They also come in a variety of forms, such as Gummies, liquids, and capsules. Choosing the best fish oil supplement for your requirements and including it in an acceptable food plan will help you achieve the greatest results. More isn’t necessarily better when it comes to consuming omega-3 fish oil. In actuality, excessive consumption may have a negative net effect.
