Nested Naturals Vegan Omega-3 is proudly made from vegan algal oil. Our marine algae is grown sustainably on a farm, not harvested from the ocean, which allows us to tightly control the purity and quality. It's a win-win. You get a boost of pure Omega-3 fatty acids and the fish swim free. Omega-3 fatty acids are pretty awesome—they have been shown to promote eye and joint health. High concentrations of Omega-3 fatty acids are found in the brain and appear to have a supportive role in memory and cognition. We add green tea leaf extract to keep the formula fresh and fresh from rancidity. We are super stoked about Vegan Omega-3 for your health and for the oceans.
