No. Krill oil is a real ingredient that does what it says on the molecule: it supplies EPA and DHA bound to phospholipids. What is sometimes a scam is the marketing around it, the miracle absorption numbers and the two-week arthritis promises that the evidence does not back. Some products have also tested weak. So the honest answer is: not a scam, but not magic, and worth reading the label.
We make Captains Krill Oil™, so weigh that. We are going to tell you where our own category earns the suspicion.
What is real
Krill oil is an omega-3 supplement made from Antarctic krill. Its EPA and DHA ride in phospholipids rather than the triglycerides in most fish oil, and it carries a small amount of natural astaxanthin. Those facts are not in dispute. Whether that form does something measurably better for you is a separate question, and that is where the hype starts.
Where the scam reputation comes from
1. Claims that ran ahead of the science. In Australia, Monash University researchers Ken Harvey, Aaron Kovacs and Grace Jackel wrote in The Conversation about a krill oil advertising campaign promising relief of arthritis symptoms within 7 to 14 days, “superior absorption” and “9x” the strength of fish oil. They traced the arthritis claim to a single 2007 study of 90 people, many without arthritis, with no independent replication they could find, and noted a 2014 review that found no evidence krill oil is better absorbed. In May 2013 an Australian advertising complaints panel ruled that the “9x stronger” and 7 to 14 day claims breached the advertising code. The piece is on Foodwatch. It argues the marketing was the problem, not that the product was fake.
2. Weak products. In 2010 ConsumerLab tested 24 fish, algal and krill oil supplements and found problems in 7. One krill product failed on both spoilage and low omega-3, and another sold as krill oil contained more fish oil than krill oil. The report did not name those krill brands, the sample was small, and it is 15 years old, so treat it as a warning about checking, not a verdict on the category. Summary at New Hope Network.
A 2011 trade report quoted a krill supplier saying some products labeled krill oil held “next to no phospholipids”, one at about 0.5% against 40% or more in genuine product. That claim came from a competitor and named no brand, so it is a flag, not a finding. See NutraIngredients.
3. Ads that call all other omega-3 a scam. Dr. Harriet Hall at Science-Based Medicine took apart a newspaper ad that called fish oil a “$1.2 Billion Fish Oil Scam” to sell a krill-and-squid blend, and found the product’s benefit claims unsupported by clinical trials. The scam in that story was the ad. Read it at Science-Based Medicine.
Five signs of a bad krill oil
- A fantasy number. “Nine times stronger” or “60% more absorbed” with no study you can open.
- A disease promise. Krill oil is a supplement. It is not a treatment for arthritis or anything else.
- No phospholipid figure. If the label hides it, that is the main thing krill is supposed to bring.
- A fishy or sharp smell. Fresh oil should not smell rancid; see what fresh krill oil smells like and how to tell if it has gone off.
- No answer on extraction. A seller who will not say how the oil was made is telling you something. We cover the question in Is krill oil extracted with hexane?
What we can and cannot tell you about ours
Captains krill is mechanically extracted on the boat, with no chemical solvent at any stage. It is a natural catch, so EPA and DHA vary a little from lot to lot. We test lots at random and they come back strong, and documentation is available on request. We have been in business 20 years. Walk through the process in Boat to Bottle. We will not tell you it absorbs several times better than fish oil, because nobody has shown that, and we are not going to claim a benefit we can’t back.
You might not need us
If you eat oily fish twice a week, you probably have no omega-3 gap to fill, and no bottle, ours included, will change that. If you simply cannot take fish oil because of the burps, krill is a reasonable thing to try. If price is the main thing, a good triglyceride fish oil does the same core job for less.

Frequently asked questions
Is krill oil a scam or does it work?
The ingredient is real: krill oil delivers EPA and DHA in phospholipid form. What is overstated is the marketing around it, such as claims of much better absorption or fast joint relief. Evidence for those is thin, so judge any bottle on what it contains, not on the promises.
Is there fake krill oil?
Yes, in the sense of weak products. A 2011 industry report described a krill product with almost no phospholipids, and a 2010 ConsumerLab test found a product sold as krill oil that contained more fish oil than krill oil. Both are old and neither named a brand, but they show why labels deserve a look.
Does krill oil absorb better than fish oil?
Maybe slightly, but not proven. A 2014 review found no evidence it is better absorbed, and the small studies that favor krill are not enough to call it settled. The phospholipid form is a reasonable reason to try it, not a guarantee.
Why is krill oil so expensive if it isn’t magic?
Krill is small, carries little oil, and is harvested and processed far from shore. That is a cost story, not a potency story. We broke it down in our piece on why krill oil costs more.
How do I avoid a bad krill oil?
Check the supplement panel for phospholipid content, ask how and where the oil was extracted, and smell a capsule you cut open. Rancid or fishy oil is a bad sign. Ask for documentation and see what the seller can actually show.
