In today’s post we will look at Costco’s Fish Oil selection and compare them to my two “gold standard” fish oil supplements. This will be the ultimate cost benefit analysis and will hopefully help you make a better decision about the best fish oil supplement for your needs and budget.
Kirkland Signature™ vs. Nature’s Bounty® vs. Nature Made® vs. Nordic Naturals® vs. Carlson®
Some time ago I changed the way I recommended fish oil. This was mostly based on anecdotal evidence from “those in the know” that certain brands were far superior, not only in taste but in quality and efficacy.
This has been backed up by scant evidence. And the more research I do the more I have began looking again at traditional low cost brands. Especially those from Costco.
I have been sending my patients to Costco for years. Mostly because of availability, quality and their wonderful bulk pricing. Not everyone can afford to fork out $324 (The cost of a 1 year supply of Nordic Naturals Ultimate Omega).
This was a fun blog post to write because the results were completely surprising and I will probably change my fish oil as a result.
And the winner is? (Scroll to the bottom to see the results)

Discussion
The Costco Comparison
Based on ease of use (total tabs per day), cost, EPA/DHA ratios, and palatability. Both the Natures Bounty Enteric Coated and the Kirkland Brand Enteric Coated fish oil seem like very good deals.
I have taken the enteric coated Kirkland brand tabs and found that even though they are enteric coated they taste poor and still cause the proverbial “fish burps”. I have yet to try the Natures Bounty brand but I think I will give it a try.
Premium Brands
When it comes to premium brands I currently take Nordic Naturals – Ultimate Omega/Lemon Taste soft gels. After seeing the comparison and price structure it seems as though Carlson Labs may be a better bet. You would get significantly more omega 3 with a good EPA/DHA ratio at a lower cost. I have heard they are also quite palatable and have a good track record for quality and purity.
Final Thoughts
I will probably continue to dish out the extra dough for a premium fish oil. I say this because I have found since taking the Nordic Naturals I never get a fishy aftertaste and I feel confident in the quality of the fish oil. For the first time I actually look forward to taking my fish oil… Something I used to hate while taking the Costco brand. The end result over the last 9 months is that I have hardly missed a dose. My serum cholesterol levels have been better than ever (not that that probably matters but it is a good metric).
