Krill Vs Fish Oil

Have you ever found yourself standing in the supplement isle staring at the fish and krill oil supplements not knowing which one to choose? You are not alone in the confusion. There has been a lot of hype in the media regarding the effectiveness of krill oil in comparison to fish oil which can leave us, as the consumers, stumped as to which supplement we should choose. This post will break down the pros and cons of the two supplements.

 

Krill Oil

Pro’s- Krill oil has gained a large amount of attention as of late, as it has been found to be a rich source of the omega 3 fatty acids, EPA and DHA. The main reason as to why it has gained so much attention is because studies have found the body absorbs krill better due to the phospholipids being packed differently in comparison to fish oil.  Krill oil also contains the antioxidant astaxanthin, which is 48 more times effective than fish oil in reducing free radicals in the body.

Con’s- The scientific research on krill oil is at the beginning of its days and many more, good quality studies are needed to prove the effectiveness of krill. There is also concern over the sustainability of krill oil. Yes, there is a lot of krill in the ocean, but what concerns marine biologists is the harvesting of krill concentrations near the feeding grounds of whales and other marine mammals. Marine species are already threatened and stressed by climate change, their feeding grounds are being eroded or altered in a way that poses a real danger to the sustainability of local marine mammal populations.

 

Fish oil-

Pro’s- Fish oil has many years of scientific research behind it, confirming its effectiveness in treating an array of health conditions.  The conditions in which fish oil has been proven its effectiveness are cardiovascular conditions, joint pain, cognitive function and mental health, including symptoms of stress and depression.

Con’s- Potential heavy metal contamination is a serious concern if the oil is purchased from a cheap and unreliable company. Consumers need to ensure they are purchasing good quality fish oil.

 

Conclusion- There is certainly a place for both of these oils on the market, as they can complement each other nicely. Some people may not need the antioxidant properties that krill oil contains and therefore fish oil may be the better option for them. Every individual is different requiring a different treatment plan.

The most important thing is that we consume as much omega-3 fatty acids from dietary sources as possible and supplement when required or when experiencing inflammatory conditions.

Dietary sources of omega 3- flaxseeds, salmon, chia seeds (soaked is best), walnuts, mackerel and sardines.
