What is the Difference between Krill Oil and Fish Oil?

Both krill oil and fish oil are famous for promoting fat loss, reducing inflammation, improving heart health, decreasing joint pain, providing relief for certain PMS symptoms, and regulating mood levels. Both are also great sources of Omega 3 fatty acids since both are rich in EPA and DHA. However, there has been an ongoing debate between the efficacy and benefits of krill oil against those of fish oil. There are people who say that krill oil is the better option, while others argue that fish oil works better. To know if either one of these oils is better than the other, one must know how both are different from each other. So what is the difference between krill oil and fish oil?

Krill oil versus fish oil

One of the main differences between krill oil and fish oil is where both oils come from. Krill oil comes from a sea creature that looks like a small shrimp and is obviously called krill. It is usually the food base for many other sea creatures. On the other hand, fish oil comes mostly from fish sources such as salmon, mackerel, tuna, trout, sardines, halibut or herring, and other oily fish.

There are many people who support krill oil and claim it as the “miracle oil” for certain diseases and illnesses. And there have been some media and a number of academic reports that support this claim. Several studies have shown that krill oil actually contains more antioxidants than fish oil. This number allows krill oil supplements to be absorbed by the body more quickly than when fish oil supplements are taken in. And other people who support krill oil reason out that why they favour it is because of the absence of any aftertaste that is very common with fish oil supplements.

Both krill oil and fish oil are also able to decrease symptoms of depression and arthritis pain, and also promote weight loss. However, it is the side effects of any supplement (such as krill and fish oil) that can either promote the supplement or not. Common side effects coming from fish and krill oil are diarrhea and indigestion. An increase in the risk of bleeding is also a common side effect with both oils. But since both kinds of oil come from types of seafood, a main side effect with both is an allergy for those who are allergic to seafood. So basically, both krill oil and fish oil have the similar side effects since both are from seafood.

Another matter that should be considered with krill oil versus fish oil is the production. Krill fishing is not yet being regulated, so krill is being overfished and this poses a bigger problem for the ecosystem. As for fish oil, many of the fish that provide such oil are taken from areas that follow fishing regulations. This makes sure of the balance between the growth rate of the population and its decrease due to fishing. So if one cares for the environment, promoting krill oil will in a way, also promote unregulated krill fishing.

The similarities and differences in the production, benefits, and side effects of krill oil and fish oil allows further room for debate on which is a better supplement. More scientific studies are still needed to clearly line the contrast between krill oil and fish oil.
