The primary difference between DHA and EPA lies in their structure and biological function. DHA is a fatty acid with 22 carbon atoms and six double bonds; EPA has 20 carbon atoms and five double bonds. DHA and EPA are found in varying amounts in plant and animal sources. Daily intake of these fatty acids can contribute to a balanced diet. For those seeking a plant-based alternative, algae oil capsules are a possible source of both DHA and EPA. By choosing algae oil, one can avoid the use of fish oil and make an environmentally conscious, plant-based choice.

Algal oil is extracted from microalgae, the primary source of DHA and EPA in nature. The production of algal oil requires fewer resources than that of fish oil. Plent's vegan omega-3 supplements are made with specially selected microalgae. They are a possible source of omega-3 fatty acids for people who pursue a plant-based lifestyle.
