Difference Between Fish Oil and Krill Oil

Fish Oil vs Krill Oil

Both fish oil and krill oil provide extra strength to the health of people due to the presence of many important constituents. Despite the fact that both include fatty acids and some antioxidants, the effectiveness is different in the two types of oils. This article summarises the particular contents and the nature of both fish and krill oil and then discusses the important differences between the two.

Fish Oil

As the name simply implies, fish oil is the oil or fat extracted or derived from fish. There are particular species of fish that have been identified to have considerable levels of oil in their tissues; sharks, swordfish, tilefish, and albacore tuna are amongst the famous oily fishes. Fish oil is extracted from different types of tissues and organs of fishes such as liver. Fish oil, in fact, has become a commercial trade due to the great importance in fields such as health and medicine of both humans and animals; fish oil is in the forms of either capsules or syrups. In addition, the use of fish oil contained pellets is could be noticed as an aquaculture feed. The presence of omega-3 fatty acids in fish oil is highly regarded by many scientists. In addition, the presence of Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA), and Eicosanoid precursors could be considered as added values of fish oil. Furthermore, there are high amounts of antioxidants viz. iodine and selenium in fish oil. All those constituents are highly beneficial for the health of people. Clinical depression, anxiety, and cancer are amongst the major conditions that are treated by fish oil.

Krill Oil

The oil derived from the zooplankton species of krill is called the krill oil. Krill is a shrimp-like small invertebrate crustaceans living in water. Consumption of krill oil provides high amounts of free omega-3 fatty acids and phophatidylcholine astaxanthin, which are very important for the health of animals including the man. The presence of omega-3 fatty acids conjugated with phospholipids poses an elevated level of importance to the krill oil. Heart patients are particularly benefitted from the use of krill oil, as there are powerful antioxidants. High levels of triglycerides and cholesterols could be treated using krill oils. High blood pressure, stroke, cancer, and osteoarthritis are among other treated problems using krill oil. In addition, krill oil could be used for premenstrual syndrome (PMS) as well as for painful menstrual periods. One of the great advantages of krill oil consumption is that the absorption into the body takes place without any delay.


What is the difference between Fish Oil and Krill Oil?

Despite the fact that both fish and krill belong to the major ecological group of zooplankton, there are some important differences exhibited between those and following are some of the very important ones to know.

However, the first distinction could be stated as that fish oil comes from fish (vertebrates) while krill oil comes from krill (invertebrates).

• The content of antioxidants is higher in krill oil than in fish oil.

• Krill oil is more easily absorbed into the body compared to fish oil. Therefore, krill oil consumption is more effective than fish oil.

• Krill oil does not have a particular taste but fish oil capsules do.

• Medicinal value is higher in krill oil compared to fish oil.
