If you’re looking for fish oil reviews of every single fish oil product available, you won’t find it here…

Instead, we review the 5 most popular fish oil brands currently available from many health food stores and on-line retailers.

According to our information in How to Buy the Best Fish Oils, we strongly stressed the importance of calculating the total omega 3 fatty acid concentration and determining the purity before buying you buy any fish oil.

Using the above criteria, we review Carlson Labs, Spring Valley, Dr. Barry Sears, Nordic Naturals and Minami Omega 3 products.

The reviews are based on the pharmaceutical-grade, high omega 3 levels and reported manufacturing principles.


1. Carlson Labs Fish Oil Review

  • I believe this is one of the most popular brands available in North America.500 ml bottle of lemon-flavored Carlson Fish Oil review

  • They have over 25 different kinds of fish oils, from flavored and unflavored liquids to children’s orange flavored soft chews.

  • They claim that all of their products use deep ocean fish from the Norwegian Sea which are processed and bottled in Norway.

  • The product line is tested for EPA and DHA concentrations and purity by an independent, third-party laboratory using Internationally-accepted regulations.

  • Carlson’s Very Finest Fish Oil is also one of the most popular liquid fish oil supplements currently selling in North America.

2. Spring Valley Fish Oil Review

  • If you’re looking for a general fish oil at a budget price, you may like this particular product. You can usually find it at your local discount superstore or drugstore.bottle of One-Per-Day Omega-3 Spring Valley Fish Oil review

  • Spring Valley Fish Oil comes in an enteric-coated soft gel with 30% omega 3 fatty acid concentrations.

  • It contains a proprietary omega 3 supplement called MEG-3. It’s reported to be tested to meet to a number of quality standards, including standards set by Health Canada and the United States Food and Drug Administration (FDA).

  • Comes packaged in 1000 mg. soft gels and you can purchase them in 60 to 250 count per bottle.

Additional Links for Fish Oil Reviews

  1. One of the most popular sites to check purity and dosage amounts is the IFOS – International Fish Oil Standards. This is third-party company that independently tests the label claims on a variety of fish oil supplements. The testing program is voluntary and companies have to pay a fee to submit their products for analysis. The IFOS provides a Consumer Report that gives you detailed results of the amount of omega 3 fatty acids, contaminants and purity levels…and it’s all free of charge to consumers.
  2. Consumer Reports recently published a review of the 15 most-popular omega 3 fish oil supplements. You normally have to pay a fee to become a member of Consumer Reports to view their report, but if you click on a link at the bottom of the page stating, “See the Ratings charts as they originally appeared in the issue of Consumer Reports Magazine. (link) Fish-oil pills (link)” a pop-up window will appear with a brief summary of their test results. A couple of products tested false-positive, due to inclusion of lemon-flavorings which may have affected the overall scoring process. However, their findings claim that most products met requirements of the European Union and the U.S. Pharmacopeia.
  3. ConsumerLabs is another consumer advocate website that publishes an extensive review of dozens of fish oil and krill oil supplements. You also have to pay a nominal fee to access the results of their report but their reviews are reported to be the most extensive and detailed.
