Simris® Algae Omega-3 is a plant-based alternative to fish and fish-oil. By harvesting algal oil from microalgae grown in closed systems in greenhouses, we get a vegan alternative that doesn't contribute to overfishing and is free from environmental toxins, but with the same benefits as fish-oil. Omega-3 is essential for heart, brain and vision. Simris is a great option for vegans, vegetarians, those allergic to fish or anyone who cares about the planet.
