Our Algae Oil is a phenomenal, concentrated source of the Omega-3 Fatty Acids EPA and DHA. Additionally, because it is grown in bioreactors, it contains fewer contaminants and is significantly more sustainable than fish or even krill oil. Plus, it doesn't have a fishy smell for those who don't like the smell of fish. K9 BioActives Difference * Ours Contains Both EPA and DHA. Many algae oils only contain the omega-3 fatty acid DHA. While DHA is a wonderful addition, ideally, we would like to add both EPA and DHA, not just DHA. Non GMO and Non Mutagenic * While there are a few Algae oils that contain both EPA and DHA; this was the result of mutagenic breeding of Schizochytrium spp, which allows them to still claim that the algae are non-GMO.
