Fish Oil Versus Krill Oil
Fish Oil or Krill Oil – Which is Better?
Fish oil is known to have various benefits to our health, and krill oil shares the same beneficial effects of the former. Both these oils contain pretty much the same components, but many studies have resulted in concluding that one is better than the other. Whether which one is superior may not be answered by most medical experts, but some believe that scientific studies portray a clear difference between fish oil and krill oils capabilities.
Both fish oil and krill oil have been used for improving a number of health issues. These oils both help in reducing bad cholesterol (LDL) levels while increasing the level of good cholesterol (HDL). They also aid in giving relief to several premenstrual syndrome (PMS) symptoms, as well as the symptoms of prostate enlargement or benign prostatic hyperplasia. Other benefits of these oils include fighting inflammation and pain, improving eye health, and treating ADHD in children.
Fish oil is known to be a good source of the omega 3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). These substances have been studied for the benefits they could give to overall health. Fish oil had been part of various health supplements, as well as processed foods, and had also been marketed as a supplement of its own. As based on the American Heart Association (AHA), Food and Drug Administration (FDA), and World Health Organization (WHO), this particular oil greatly helps in decreasing the risks of many cardiovascular illnesses, especially strokes and heart attacks.
Krill oil, on the other hand, also contains the EPA and DAH omega 3 fatty acids, but in a rather different structural form. The omega 3 fatty acids in this oil are formed in a two-chain phospholipid structure, unlike in fish oils, where these are in triglyceride structure. In krill oils, an astaxanthin molecule is stuck in the phospholipid’s EPA leg.
Astaxanthin has shown to hold powerful antioxidant properties, and with the phospholipid structure, the omega 3 fatty acids in krill oils become more absorbed by the body than those in fish oils’. Omega 3 fatty acids in fish oils have a bioavailability of around 65 percent, where in krill oils, the omega 3 fatty acids have a bioavailability of approximately 95 percent, which means it would take more amounts of fish oil to match the same quantity of omega 3 fatty acids taken from a particular amount of krill oil.
There are many clinical studies that supply information where one could conclude the superiority of krill oil from fish oil. However, for some, these may not be sufficient data for coming into a statement that krill oil is better than fish oil.
