Omega-3 and Omega-6 Ratio in Pet Food

Pet food is often high in Omega-6 but low in Omega-3. Too much Omega-6 and too little Omega-3 can lead to several health problems for your dog or cat. The difference between Omega-3 and Omega-6 fatty acids is based on molecular structure. A ratio of about 4-1 Omega-6 to Omega-3 is considered optimum for dogs but many commercial dog foods contain ratios of 20-1.

Omega-6 vs. Omega-3 imbalance may lead to:

  • Inflammation
  • Allergy like symptoms
  • Pour coat or skin
  • Joint problems
  • Overweight and obesity

But why is there too many Omega-6 in my pet diet?

Most live-stock is grain-fed, which is high in Omega-6. Since most pet foods including raw food contain much more Omega-6 fatty acids than Omega-3 fatty acids, many pet food companies have added Omega-3 fatty acids to try and compensate for this difference.  However, the cooking and processing of most commercial pet foods does destroy some of the fatty acid content. Supplementing with a bioavailable Omega-3 can restore the balance.

Why Seal Oil?

The best Omega-3 / Omega-6 Ratio

A concrete example comes to us from Norway where a study (Bjørkkjær et al. 2006) clearly concluded: “… administration of seal oil normalised the n-6 to n-3 Fatty Acid ratio and improved the bodily pain dimension of health related quality of life of patients ….”

The ratio of SeaDNA Omega-3 Seal Oil is almost 8:1 in favour of Omega-3, an excellent balance to help promote better overall health. And as science has shown us, seal oil is proven to improve the critical Omega ratio.

Contains DPA

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 your pet.

More easy to absorb

Scientific studies have shown that the mammalian molecular triglyceride structure of the seal is more easily accepted by your pet’s body than the foreign fish molecular structure. This means optimal digestion and absorption for better results.

10 X More efficient

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.

So the answer to the question “Will Omega-3 help my pet” is: “Phoque” Yeah!
