Ultra EFA is a concentrated liquid omega-3 for dogs and cats, built on a premium marine lipid concentrate rich in EPA and DHA. These fatty acids support cellular health, cardiovascular function, and a healthy inflammatory response, which is why Ultra EFA is often chosen for pets dealing with joint stiffness, skin flare-ups, or general wellness needs. Fish oil oxidizes quickly once opened, so this formula adds rosemary extract and vitamin E as natural antioxidants to help protect the fatty acids and preserve potency. The liquid format makes dosing simple across different pet sizes. Ask your veterinarian how much omega-3 fits your pet's weight and health needs.
