Nutrition and Dietetics Department Res. See. Eda Balcı explained the differences between fish oil and krill oil and gave information about which one is more beneficial. Balcı states that fish oil is an oil obtained from the tissues of fish and is generally obtained from fish with relatively high fat content such as tuna, anchovy, herring and mackerel, while krill oil is obtained from a small shellfish resembling a shrimp living in the Antarctic Ocean. He underlined that Antarctic krill does not consume pollutants and heavy metals like other fish, saying it is oil.
Drawing attention to the fact that EPA and DHA, the omega 3 fatty acids found in fish oil, have positive effects on strengthening the immune system, reducing inflammation and improving the symptoms of some psychiatric disorders, especially cardiovascular diseases, Balcı said, “For this reason, fish or fish oil As an alternative to fish oil, krill oil, which contains EPA and DHA, has a positive effect on many other diseases, especially cardiovascular diseases, due to the fatty acids it contains. “It is different from fatty acids and this affects the way the body uses them,” he said.
Stating that Omega 3s obtained from fish oil are found in the form of triglycerides, Balcı said, “Therefore, it can cause both an unpleasant fish taste in the mouth and cause complaints such as rancidity, burping, burning. At the same time, our body can benefit less from these supports in the form of triglycerides. “Omega 3s in krill oil are in the form of phospholipids. The bioavailability of Omega 3s in the phospholipid structure, that is, the amount digested and absorbed by the body, has been reported in studies that are much higher than those in the form of triglycerides.
Stating that krill oil has an antioxidant structure and has 48 times more antioxidant properties than fish oil, Balcı said, “At the same time, fish oil has a shorter shelf life than krill oil because it tends to rapidly oxidative degradation. Fish oil is yellow or golden in color, krill oil. “It is red in color due to the astaxanthin pigment that provides antioxidant properties.”
Stating that krill oil is known to increase plasma EPA and DHA concentrations, reduce inflammation, lower LDL cholesterol called “bad cholesterol” and increase the concentration of HDL cholesterol called “good cholesterol”, Balcı concluded his words as follows:
“Despite all this information, scientific research on krill oil is still inadequate and there is no definitive information about its side effects. Since krill oil is a relatively new product, more scientific studies are needed to explain its health effects and compare accurately with fish oil. “
