Pure Krill is the best omega 3 supplement for dogs. It's packed with omega 3s as well as phospholipids, which deliver the omega 3s right to where your dog's body needs them most (making it a better option than fish oil). Pure Krill for dogs also contains a potent antioxidant called astaxanthin, which protects cells inside and out and promotes healthy aging, and a nutrient called choline, which supports brain, heart, and liver health. It's far superior to other krill supplements (like krill oil that quickly goes rancid and krill chews that are full of additives). It's also more efficient and more potent than other sources of omega 3 like fish oil and flax oil. And on top of all that, Pure Krill is sustainably-sourced and traceable. And unlike krill oil, Pure Krill uses the whole krill, so there's no waste. Pure Krill is just 100% wild-caught Antarctic krill and nothing else — and it's missing from your dog's bowl!
