Krill Oil V Fish Oil
Krill Oil V Fish Oil
It’s no secret that omega-3 fatty acids are performance optimisers. First, they are considered essential fatty acids, meaning our bodies cannot make them, so we MUST obtain them from our diet (mostly through salmon, sardines, tuna and other fatty fish).
Additionally, omega-3’s are so heavily backed by research that they’re only the second food source the FDA allows to make health claims:
“This new qualified health claim for omega-3 fatty acids should help consumers as they work to improve their health by identifying foods that contain these important compounds.”
Dr. Lester M. Crawford, Acting FDA Commissioner.
How is Krill Oil Better Than Fish Oil?
Compared to fish oil, Krill Oil has:
- Less contamination.
- Better absorption rates.
- A more stable structure that is less prone to oxidation.
- Higher antioxidant activity
Krill Oil – Less Contamination than Fish Oil
Polluted seafood is nothing new. Unfortunately, not every supplement company in the world is as picky about their sourcing as our suppliers are. In 2014, the New York Times reported an independent study from LabDoor that tested 53 fish oil supplements.
49 of 53 contained mercury and all 53 tested positive for PCBs – or polychlorinated biphenyls – a known carcinogen (cancer causing compounds) that has made its way into our water sources.
Obviously, contamination with mercury, rancidity (TOTOX score), and PCB content may contribute to the development of adverse health effects. Compared to fish oil, Krill Oil reduces our risk of introducing these toxins into our body.
Krill Oil more Bioavailable than Fish Oil
Both Krill Oil and Fish Oil contain the omega-3 fatty acids EPA and DHA. In fish oil, these fatty acids exist as a delicate triglyceride. Krill Oil, however, is a phospholipid. This stable phospholipid structure is the same structure utilised by a majority of our cell membranes. This structure increases absorption rates, even allowing Krill Oil to penetrate to the cell’s nucleus.
Krill Oil – Less Likely to Oxidise
Omega-3 fatty acids are not stable and are very susceptible to oxidation. Oxidised fats damage proteins, DNA, and wreak havoc on our cellular structure and accelerate the ageing process.
The same phospholipid structure of Krill Oil that increases absorption may also increase stability meaning you get less oxidation and more of the health promoting benefits you want.
Krill Oil Boasts Higher Antioxidant Activity Than Fish Oil
Krill Oil contains a compound that has been called Nature’s most powerful antioxidant – astaxanthin. This microalgae is a member of the carotenoid family and it is such a large part of salmon’s diet that it is the reason salmon are pink!
In addition to astaxanthin, Krill Oil also naturally contains Vitamins A, D, and E, and when the ORAC (Oxygen Radical Absorbance Capacity) value of krill oil is compared to fish oil, it is 48 times more potent than fish oil!
