More pet parents are adding krill oil to their dogs’ diets to support healthy skin, a shiny coat, comfortable joints, and everyday wellness. This natural source of omega-3 fatty acids also contains astaxanthin, a powerful antioxidant that may provide additional health benefits. Here are 10 reasons krill oil for dogs is gaining attention among owners who want simple, effective nutritional support.

#1 – Has less mercury than salmon oil

Krill is a small crustacean similar to shrimp that‘s the primary food source for the largest animals on earth – whales. Since krill is lower down the food chain than salmon, it’s less likely to absorb mercury and other heavy metals, toxins, and pollutants.

#2 – Higher absorption rate than fish oil.

Krill oil contains phospholipids, which are tiny packets of fatty acids that are the building blocks for your dog’s cellular membranes. This allows the fatty acids to easily pass through your dog’s intestinal wall cell membrane. This leads to a higher absorption rate.

#3 – Improves skin and coat

Fat supplements in general and krill oil supplements in particular reduce dander and shedding and promote healthy skin and coats. It may also reduce the itching, redness, and hotspots caused by chronic allergies.

#4 – DHA helps older dogs stay sharp

Krill oil contains Docosahexaenoic acid (DHA), which studies suggest helps older dogs stay more alert, remember more, and retain the ability to stay sharp. DHA given to mother dogs during gestation and lactation is shown to improve the neurological development of puppies.

#5 – Sustainable food source

Krill is among the species with the largest total biomass. They reproduce quickly and are at less risk for overfishing than other fish species. Krill is much more sustainable than most other seafood.

#6 – More concentrated than other fish oils

Since krill oil is more concentrated and more easily absorbed than other fish oils, your dog only needs about one fifth the amount. So while the price may at first seem high, the value is there due to the high bioavailability and concentration. For example, this krill oil supplement only needs to be given to your dog every other day.

#7 – Helps reduce joint pain

Gamma linolenic acid (GLA) is a powerful anti-inflammatory that may help reduce joint pain, especially in dogs with arthritis. It also fights dry skin and noses as well as cracked skin on the pads of the feet.

#8 – Aids in brain and liver function

Krill oil assists with the absorption of carnitine from the digestive tract. Carnitine is essential for mitochondrial function, which supplies the brain and liver with energy.

#9 – Contains antioxidants

The natural antioxidant protection in krill oil helps to guard against the oxidation of Omega-3 fatty acids and damage from free radicals.

#10 – Promotes cardiovascular health

While not proven to reduce the risk of heart attack and stroke, there is evidence that it can help lower cholesterol, triglycerides, and blood pressure, which helps keep your pooch’s heart healthy.

Krill oil can be a valuable addition to your dog’s routine when chosen carefully and served in the right amount. Look for a high-quality supplement made for pets, follow the feeding instructions, and speak with your veterinarian before making dietary changes. With proper guidance, you can decide whether krill oil is a suitable choice for your dog’s individual needs.
