Fish Oil vs. Krill Oil – What’s the Difference?

fish oil vs. krill oilThe debate about which is better – Fish Oil vs. krill oil – continues to rage on. Understanding the differences between these two products can help you make better decisions regarding your health and safety, as well as your wallet. There are many differences between the two, but Fish Oil reigns supreme in the end.

How are they Made?

Fish Oil can come a variety of oily fish species, including herring, salmon, trout, tuna, and even mackerel. In some cases, it is also extracted from Cod liver or whale and seal blubber. On the other hand, krill oil comes from a very small crustacean that only grows up to six centimeters long. Because krill are harder to collect and more processing is required to extract the oils, the difference in cost between Fish oil vs. krill oil is substantial. Fish Oil is generally far less expensive.

Fish Oil vs. Krill Oil – Truth in Advertising

Unlike many other products in the United States that are considered dietary supplements, Fish Oil is actually FDA approved to lower triglyceride levels. Because of this, the FDA requires the manufacturer to disclose any ingredients other than the actual oil. Krill oil, on the other hand, is not FDA approved, which means the manufacturer is not held to the same marketing standards. Many manufacturers of krill oil will label the product “Krill Oil”, even though the product contains up to 49% low-quality fish oil – and at an inflated price.

Fatty Acids per Dose

When comparing Fish Oil vs. krill oil, it is important to note that a single dose of Fish Oil contains about 30% EPA and DHA omega-3 fatty acids. Krill oil only contains 14%, but is less prone to oxidation and rancidity. What’s more, people argue that krill oil contains antioxidants that fish oil does not. This antioxidant, known as astaxanthin, has not been studied enough for scientists to fully understand its benefits.  Fortunately, the manufacturers of high-quality Fish Oil include natural vitamin E, which not only prevents oxidation, but also acts as a well-known antioxidant with very clear benefits. With the addition of vitamin E, Fish Oil offers the same benefits as krill oil with a higher concentration of omega-3 fatty acids.

The Argument over Absorption

The number one argument in the Fish Oil vs. krill oil debate has to do with absorption. Some experts say that even though Fish Oil contains twice as much omega-3s as krill oil, the omega-3s in krill oil are more easily absorbed into the body, which makes them more effective. The absorption rates of EPA and DHA from krill has not been proven definitively better than Fish Oil, and even if the absorption rate is better, the overall amount of omega-3s absorbed into the body would be the same dose-for-dose whether an individual chose Fish Oil or krill oil. Because Fish Oil is far less expensive, it is the logical choice.

In the Fish Oil vs. krill oil debate, many people believe that krill oil is superior due to its higher rate of absorption. Keep in mind that this is not a definitive statement and more studies are needed to back this argument. Fish Oil is less expensive than krill oil, contains what it claims on the label, and provides all of the omega-3s you need each day.
