Seal Oil contains the link in the Omega-3 chain that all other Omega-3 supplements now sold are missing: DPA (docosapentaenoic acid). This compound occurs naturally in few places: Seal Oil and a mother’s breast milk are two.  DPA amplifies the positive impact that EPA and DHA can have on the body and provides other numerous benefits!

Scientific studies have shown that the mammalian molecular triglyceride structure of the seal is more easily accepted by the human body than the foreign fish molecular structure. This means no “fishy burps” and optimal digestion and absorption for better results.


A scientific study has shown that the maximal stimulation of endothelial cell migration by DPA pre-treatment was achieved using only 1/10 of the required EPA concentration.  These data suggest that the effect of EPA on endothelial cell migration occurs via DPA, and that DPA plays an important role in repairing damaged vessels.


Scientific studies have shown that DPA is a better antiplatelet than EPA and DHA, reducing the risk of blood clots and improving cardiovascular protection.


SeaDNA 100% natural seal oil offers a unique and natural alternative to the often heavily processed and concentrated fish oils now widely sold on the market.  Although higher levels of EPA and DHA are now possible through this process, the resulting product is far removed from its “natural” beginnings and bioavailability is often decreased.  Watch our video!


Our products are harvested in the pristine, icy waters of Northern Canada around the coasts of Newfoundland and the Magdalen Islands. Most of the fish oil sold in Canada comes from Peru or Chile, where anchovies and sardines are caught and cooked, and the oil is separated out.




A study conducted in 2015 has shown that seal oil has a very beneficial effect on athletes:

  • Enhanced muscle activation performance (20 ± 18 %)
  • Maintained sprint performance from attenuated Wingate % power drop (4,76 ± 3,4%)

Seal oil was chosen because mammalian (seal) triacylglycerol molecules have Omega-3 fats primarily in the sn-1 and sn-3 positions, as opposed to the sn-2 position of fish oil. Fats in the sn-3 position are preferentially cleaved by sublingual lipases, and the sn-1 fat is cleaved in the small intestine, while the sn-2 fatty acid is left for later esterification. This difference has been shown to promote faster digestion of N-3 seal oil leading to higher incorporation in non-hepatic tissues.

Seal Oil VS. Fish Oil

20% Omega-3

A well balanced, complete OMEGA-3 chain (with EPA, DHA and DPA in the same proportions that are found naturally in the human body) makes Seal Oil easier to process and more beneficial as a whole.

50%-90% Omega-3

Fish oil concentrates are chemically altered to increase Omega-3 levels, often using ethanol. Natural purity is sacrificed for the convenience of consuming more Omega-3 in one single softgel.


Due to a mammalian molecular structure, seal oil is more easily absorbed by the human body than fish oil. [i] [ii] [iii]


Fish oil is slower to be absorbed and can “sit” in the stomach resulting in “fishy burps”.

Contains 4% DPA

This increases the proportions of EPA & DHA for better results and is 10 times more effective than EPA in repairing damaged vessels. [iv] [v]

Contains very little or no DPA
Fish oil only contains EPA & DHA

Better oxidative stability

Seal oil has a better oxidate stability, providing a longer shelf life. [vi]

More susceptible to oxidation

100% Canadian

Our seal oil is harvested in the pristine and icy waters surrounding the Magdalen Islands and the coasts of Newfoundland.

“In my lab, using an animal model, I’ve found that seal oil is definitely better than fish oil… If anyone is consuming fish oil capsules, maybe they should switch to seal oil.”
