Krill Oil vs Fish Oil

Krill Oil vs Fish Oil

Posted by: Kevin Created Date: 06 Mar


What is Superba Krill Oil?

   Superba Krill™ oil is extracted from the Antarctic krill species Euphausia Superba. Krill are small shrimp-like crustaceans packed full of health-promoting long-chain omega-3 fatty acids (EPA & DHA), phospholipids, choline and astaxanthin. Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name krill comes from the Norwegian word krill, meaning "small fry of fish", which is also often attributed to species of fish.

Krill is considered an important trophic level connection – near the bottom of the food chain – because they feed on phytoplankton and (to a lesser extent) zooplankton, converting these into a form suitable for many larger animals for whom krill makes up the largest part of their diet.

In the Southern Ocean, one species, the Antarctic krill, Euphausia superba, makes up an estimated biomass of around 379 000 000 tonnes, making it among the species with the largest total biomass.

Superba Krill oil's natural combination and concentration of four key nutrients give an excellent opportunity for differentiation in the supplement market. 

  1. 1. OMEGA-3 FATTY ACIDS EPA & DHA

    These essential fatty acids are one of the most researched nutrients, with a wide range of health benefits for your heart, eyes, liver and brain.

  2. 2. PHOSPHOLIPIDS

    Phospholipids help omega-3s integrate into the cell membranes and may be a better delivery form to the body’s organs than other marine oils.

  3. 3. CHOLINE

    Choline is an essential nutrient vital for many body functions such as nerve signaling, liver and muscle functioning. Our body can't make enough, therefore we must obtain it from our diet.

  4. 4. ASTAXANTHIN

    This natural antioxidant gives krill oil its beautiful red colour. It also protects the oil from oxidation, eliminating the need to add preservatives.


A growing body of evidence demonstrates krill oil's beneficial effects on health across multiple categories, and Superba's krill oil is currently the only one in the world that uses FLEXTEC's patented low-temperature extraction technology instead of general high-temperature solvent extraction, so the oil is purer and of higher quality, making it easier for the human body to absorb. The SuperbaBoost selected by TAVITA, which contains 56% phospholipids, is the highest quality in the Superba oil family

Where do they come from?

    Krill are present in most oceans around the world, however, they gather together in huge swarms in Antarctica to feed on microscopic algae. This makes it possible to harvest this powerful and nutrient-rich little crustacean. Living in the pristine and unpolluted waters of the Southern Ocean means Antarctic krill are virtually free of environmental contaminants and toxins.


Why Krill Oil is better than Fish Oil?

Written by Andreas Berg Storsve - R&D Director September 08, 2017

Within the omega-3 category, there are some important differences between sources that can impact the delivery of these fatty acids to the body’s cells and tissues. In particular, krill oil’s omega-3s are mostly bound to phospholipids and therefore undergo different digestive and distribution routes vs. fish oil when they get into the body.

Because phospholipids are integral parts of cell membranes, krill’s omega-3s exhibit preferential uptake in the cells. Fish oil’s omega-3s on the other hand must be converted in the liver before they are available to the body’s cells. The increased cellular uptake has strong implications for omega-3s’ deposition in important tissues and organs such as the brain and heart.

Study: Performed by Kevin C. Maki and co-workers at the Provident Clinical Research, in Bloomington, IN, and the Meridien Research Centers, in St. Petersburg, FL, this study was set up as a randomized, double-blind parallel arm trial. Within this setup, 76 overweight and obese men and women were randomly distributed into three groups to take Superba™ Krill Oil, fish oil, or olive oil for four weeks. To avoid any influence, the supplementation given was unknown to both the study subjects and researchers.

Results: While the received daily amount of EPA was similar in the krill oil and fish oil groups, the DHA quantity was approximately half as much in the krill oil group compared to the fish oil group. Nevertheless, at the end of the study period, plasma analysis showed that the mean EPA concentrations were higher in the krill oil group compared to the fish oil group, and the mean DHA concentrations were similar in both groups. Both sources of omega-3 fatty acids were safe and well-tolerated.

Most importantly, krill oil supplementation (2g/d) resulted in increased plasma EPA bioavailability and revealed equal bioavailability in the case of DHA, but at half the dosage in comparison to fish oil. Overall, after dose adjustment, researchers noted that the total increase of EPA and DHA in the plasma of the subjects who received Superba™ Krill Oil for 4 weeks was 24% higher than that of the subjects who received fish oil.
