Is Krill Oil Better than Fish Oil?


Today we take a look at how krill oils compare to fish oil. 

Similarities Between the Two

Both Krill oil and Fish oil supply omega 3 fatty acids which are DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). These are extremely important polyunsaturated fats that are essential to certain bodily functions. A study showed that a shortage of EPA in the cells of the body could lead to thoughts of suicide. A shortage of DHA has been linked to cystic fibrosis, Alzheimer’s disease, and various attention disorders.

What is Krill Oil, Exactly?

Krill oil comes from very small crustaceans similar to shrimp which are primarily eaten by mantas, whale sharks, and Baleen whales. The word Krill actually means “whale food” in Norwegian. It is often used to help curb the effects of cancer, strokes, high cholesterol, high blood pressure, PMS pain, osteoarthritis, and depression. Krill oil contains fatty acids which are also in fish oil. It is these fats that are believed to be effective in lowering cholesterol, decrease swelling, and helps stop the formation of blood clots by making blood platelets less sticky.

There is not enough research to properly evaluate the side effects of Krill oil, but there is evidence that shows that it is safe to use. Although, it does have some of same side effects as Fish oil like nausea, heartburn, loose stools, and bad breath. That being said; it is probably not safe to use when you have surgery, simply because Krill oil can slow blood clotting.

What is Fish Oil, Exactly?

Fish oil comes from fatty fish. It promotes heart health and reduces the risk of strokes and heart attacks. Although less information is available on Krill oil; research has shown that it is just as effective at promoting heart health as Fish oil because patients showed the same increase in DHA and EPA with both types of oils. Fish oil is also used in the treatment of skin conditions like eczema and other skin conditions that cause inflammation. It is also useful for hormone regulation, joint lubrication, and more.

The Differences

Here is a list of the main differences between Fish oil and Krill oil.

  • Krill oil comes from small crustaceans while Fish oil comes from fatty fish.
  • Krill oil contains more EPA than Fish oil.
  • Less research has been done on the effects of Krill oil than Fish oil, therefore, there are no formal standards set forth for Krill oil yet.
  • Krill oil has been known to reduce fishy burps that can sometimes come with ingesting fish oil. This isn’t a proven fact, but regardless, you can avoid fishy burps by either ingesting fish oil at the beginning of a meal, purchasing odorless fish oil supplements, or freezing them.
  • Fish oil stays in the body longer because it takes longer to decompose while Krill oil breaks down much faster.

There are several advantages to both Krill oil and Fish oil, but the bottom line is, Fish oil has undergone much more testing and many of the advantages have been proven. Krill oil could turn out to be just as much, if not more, effective, but the research isn’t quite there yet.
