Fish Oil Supplements by JustFoodForDogs. Details:Our Omega Plus algae oil supplement for dogs, rich in omega 3 fatty acids EPA and DHA, provides nutritional support to promote and maintain healthy skin and coat. With a higher bioavailability than fish oil, algae oil’s active ingredients are utilized by the body more effectively. The plant-based, vegan oil is high in EPA and DHA, two omega-3 fatty acids known to support skin hydration. Algae oil is a more sustainable source of omega-3 fatty acids. Sourcing omega-3s via fishing is a dying practice. Overfishing has led to a dwindling population of fish to eat and source omega-3s from. Instead of relying on fish from the ocean, more algae can be grown without negatively impacting the environment or shared ecosystems. DHA and EPA found in fish originate from algae. By using algae instead of fish oil, your pet is getting high-quality DHA and EPA directly from the source.
