Your Gateway to Good Health

Here's Why Gateway Omega-3 Is The Best Omeaga-3 You Can Buy

Gateway seal oil omega-3 contains high potency EPA, DHA and DPA, which are all essential polyunsaturated fatty acids. Omega-3 are considered essential because our bodies need them to function optimally at every age. It’s important that we get enough Omega-3 in our diets because our body doesn’t naturally produce them.

When we are born, we have an Omega-6 to Omega-3 ratio of 1:1. Mother’s milk, considered ‘nature’s perfect food’, contains an Omega-3 to Omega-6 ratio of 1:1.


Too Much Omega-6

Too Much Omega-6

Due to high amounts of Omega-6 in our modern diets, the ratio in our bodies has soared to an average of 20:1 and even as high as 40:1, leading to what many experts have called ‘the dangerous imbalance’ of Omega-6 to Omega-3.[1]

The Dangerous Imbalance

The Dangerous Imbalance

This dangerous imbalance is suspected to have serious long-term health effects, including:

  • Chronic Inflammation
  • Increased Risk of Heart Disease
  • Increased Risk Of Leptin Resistance and certain Autoimmune Diseases
  • Reported increases in the pathogenesis of Cancer.[2]

Balance of Omega-3 & Omega-6

Balance of Omega-3 & Omega-6

Fixing this imbalance with Omega-3 supplementation is truly your gateway to good health. Since Omega-3 cannot be produced in sufficient quantities by human body, we require Omega-3 supplementation to restore the balance.
Omega-3 Supplementation can improve the long-term health of your eyes, brain, joint, bones, heart and nervous system. It truly is a critical step towards a healthy lifestyle.



While it is common to see brands tout ‘Omega-3’ in their eggs, bread and other items – the reality is that Flaxseed only converts to true Omega-3 (converts to DHA and EPA fatty acids) 10% of the time. The remainder of the ALA (the Omega-3 source in Flax) is just burned up as energy or metabolized. [3]
Of the approximate 10% that does become EPA and DHA – that small percentage is not a complete source of Omega-3, as it lacks DPA fatty acid.


  • While Fish Oils have high levels of DHA and EPA, they only have trace amounts of DPA – making it an incomplete source of Omega-3.
  • In order to get high levels of DHA and EPA in fish oil supplements, concentrated fish oils are chemically altered through ethylation.
  • Fish oils, though a better source of Omega-3 then Flaxseed, are mostly chemically altered. The World Wildlife Organization has identified overfishing as one of today’s largest threats to our planet; fish is an overall unsustainable source of Omega-3, and is not a complete source of Omega-3.


Only Harp Seal Oil contains potent levels of EPA and DHA with a third essential fatty acid: DPA fatty acid.
Research into the benefits of DPA Fatty Acid in Omega-3 began with a groundbreaking discovery in a 1980 study. The study found that the 70-year-old Inuk had a healthier heart than the 20-year-old Dane. [4] Since then, research has linked DPA fatty acid to a lower risk of cardiovascular disease. [5] Harp seal as a source of Omega-3 contains EPA, DHA and DPA. Studies have shown that the presence of DPA in Omega-3:

  • Is better absorbed [6]
  • Studies have found that DPA Omega-3 is over 22% more effective at increasing Omega-3 levels in the body.
  • Is 10X More Effective [7]
  • DPA is 10X more effective than EPA at repairing damaged blood vessel cell walls.
  • Enhances EPA + DHA [8]
  • The presence of DPA in Omega-3 has shown to enhance the heart and brain boosting benefits of EPA and DHA.
  • Benefits Memory and Cognitive Health [9]
  • Studies show that DPA Omega-3 possesses nonrestorative effects that offer benefits for memory and cognitive health.


Gateway seal oil contains the world’s most complete source of Omega-3 (EPA + DHA + DPA).

  • As a supplement, seal oil is sustainable, naturally potent, and preferred by those who experience negative side effects from fish oil like fish burps and upset stomach.
  • As a brand, Gateway has been manufactured and distributed in Canada since 1996. You can find us in stores across Newfoundland and Labrador.
  • Our refining process is one of the most thorough in the industry. We’ve even worked with Canadian and international governments on industry wide standards for quality testing and assurance.
  • It’s why Canadian families have trusted Gateway for over 25 years. Our quality assured and all-Canadian Omega-3 is the best supplement you can buy for everyone in the family. We’re proud to say it.
