The fats in krill and Fish oil
Both krill oil and fish oil contain EPA and DHA. The many advantages of EPA (eicosapentaenoic acid) and DHA (
The production process and the environment: krill and fish oil
Krill oil is obtained from krill, a crustacean species which lives near Antarctica. Fish oil is usually obtained from fatty fishes like sardines or anchovies. Fish oil is already contributing to overfishing, contrary to Krill oil. Krill oil production can increase 50 fold worldwide without any risk for the food chain. The reason for this is because the biomass of krill is very large and not in any way threatened. The food that is eaten by the creatures used for fish and krill oil is roughly the same. Both sardines, anchovies
Sometimes big fish like swordfish and sharks are used for fish oil, which is not only environmentally
The comparison of fish and krill oil
The difference between fish and krill oil are the other fats included in the oil, besides EPA and DHA. In krill
Krill oil has better cognitive per benefits per unit of EPA and DHA than fish oil. The reason might be that krill oil is better in crossing the blood-brain barrier, because of the phospholipids. When the same amount of EPA and DHA are administered, inflammation is also reduced more with krill oil than with fish oil. The reduction in inflammation might contribute to healthier joints, and could be used for a treatment of arthrosis.
What is one reason for the greater reduction in inflammation? Krill oil contains a very powerful antioxidant called astaxanthin, which is responsible for the red coloring of krill oil (and red salmon for example). It lowers oxidative stress and DNA damage. It might increase sports performance. Astaxanthin might also contribute to the creation of new stem cells. More research is needed, but astaxanthin looks very promising. Astaxanthin is only found in krill oil, and not in fish oil.

Conclusion: Krill oil is highly recommended!
Helfi recommends krill oil because it has more cognitive, anti-inflammatory and anti-aging benefits. Krill oil might be more expensive than fish oil, but is a great investment for anyone that wants to go all the way in terms of lifestyle and performance! And by using krill oil we’re saving the planet!
