Lab Tests Back Up Allegations, Report Less Omega Fatty Acids Than Label Advertises  

In a lawsuit filed in New York, one consumer claims that the label on Kirkland Signature’s Wild Alaskan Fish Oil is “false, deceptive and misleading” and violates “almost every state warranty, consumer protection and product labeling law in the United States.”

Specifically, the case points to the fact that the supplement is advertised to contain 1050mg of Omega Unsaturated Fatty Acids per soft gel. This 1050 mg dose, the suit says, is comprised of 720 mg of Omega Fatty Acids 5, 6, 7, 9 and 11, as well as 330 mg of “total Omega-3 fatty acids.” (The product also boasts 270 mg of “other fatty acids.”)

The lawsuit claims that despite these claims, the product contains a substantially lower amount of these fatty acids. In addition, the suit alleges that “there is no scientific literature” to support the claim that omega-11 fatty acids are even found in fish oil.

In light of these reports, attorneys working with ClassAction.org ordered their own independent lab tests – the results of which backed up these allegations. The test results reportedly show that the fish oil capsule contains only 40% of the advertised amount of Omega-3 fatty acids and only 21% of the advertised amount of remaining fatty acids.

A test run by Consumer Lab also reportedly found that the supplement contains only 346 mg of the advertised 720 mg of total omega-5s, 6s, 7s, 9s and 11s.

How a Class Action Can Help

A class action lawsuit could help consumers get their money back for purchasing a product that may have been mislabeled. Furthermore, a successful lawsuit could serve as a warning to Costco and its manufacturer Trident Seafoods Corporation to properly label their products.

It has been alleged that Costco knew the label on its Wild Alaskan Fish Oil was misleading and that the lack of the promised omega fatty acids “fully diminishes the value of the product.” If you purchased this product and believe you may have been duped, fill out the form on this page and share your story. Any information you provide can be helpful in getting a lawsuit started against Costco over this supplement.
